Families of Air France crash victims want answers
17 December 2009

PARIS (AP) - French aviation investigators said Thursday that new airline safety standards may be required after the crash of Air France Flight 447 cast doubt on the reliability of speed-measuring equipment in difficult, stormy conditions.

The Airbus A330 plunged into the Atlantic Ocean off Brazil's coast en route from Rio to Paris on June 1. All 228 people aboard were killed.

Many families of victims have expressed frustration with the lack of information over the past seven months. In its second report on the crash, French accident investigation agency BEA said experts still have little idea about why the plane went down.

Automatic messages sent by the plane's computers just before it crashed show the plane was receiving false speed readings from sensors known as Pitot tubes. Experts have said running into a violent storm at either too slow or too fast a speed at high altitudes could be dangerous.

The BEA said that the safety standards used to certify plane equipment -- particularly Pitot tubes -- don't properly reflect high-altitude conditions. The report called for studies of cloud masses and icy conditions that may lead safety officials to modify the criteria.

Both the European Aviation Safety Agency and the U.S. Federal Aviation Administration ordered airlines flying Airbus jets like the one that crashed to replace their French-made Thales Pitot tubes. There have been a series of incidents related to the Thales sensors.

Investigators repeatedly have insisted that that the crash was likely caused by a series of failures and not just the Pitot tubes.

"It's true that there isn't enough known about the formation of ice crystals at high altitude and the impact that has on the Pitot tubes for example," said Chris Yates, an independent aviation safety analyst based in Britain. "Having said that, what I think occurred here is very rare circumstances."

The report says the circumstances of the crash and its causes "are still not determined" but does describe some potential clues. It says there were "powerful cumulonimbus clusters" on the route flown by Flight 447 and that many planes flying in the area altered their routes to avoid the cloud masses.

Oxygen masks did not drop, and the plane did not depressurize, the report says. All of the life vests found were still in their wrappers, suggesting perhaps that passengers had little or no warning.

It also says the aircraft was probably in one piece upon impact.

The plane's black boxes are believed to be nearly 23,000 feet (7,000 meters) under water and without them investigators say they may never determine what happened.

The BEA's report called for changes to flight recorders that should make them easier to locate.

Additional beacons should be fitted to commercial aircraft and the "pingers" attached to the black boxes should emit signals for 90 instead of 30 days, it said.

The BEA also recommended studying the possibility of requiring software on planes that regularly transmits basic flight parameters.

The second and most recent search for the black boxes ended in August.

BEA head Jean-Paul Troadec has said a new, three-month hunt for the black boxes will begin in February.

The new search will include help from the U.S. Navy and the National Transportation Safety Board, along with accident experts from Britain, Germany, Russia and Brazil. Private companies also will help in the search, which will use submarines along with boats equipped with sonar gear.

Crash investigators optimistic that crashed Air France flight's black boxes will be found
22 December 2009

LE BOURGET, France (AP) - French aviation investigators said Tuesday they are optimistic about finding the black boxes of Air France Flight 447, which crashed in the Atlantic last June en route from Rio to Paris, when a third phase of the search begins in February.

An international team of experts has narrowed down the search area for the black boxes from the flight that killed all 228 people aboard to 2,500 square kilometers (965 square miles) -- a fifth the size of previous efforts to recover, said Jean-Paul Troadec, chief of the French Accident Investigation Agency.

The lifespan of the so-called "pingers" attached to the black boxes is only about a month, but officials say submarines and boats equipped with sonar gear can find the wreckage from the Aibrus 330 even without such signals.

The smaller search area should make it easier to locate the debris and the flight recorders.

"The scientists I have spoken to think that we have a good chance of finding the remains," he said at a news conference outside Paris.

Lead investigator Alain Bouillard said he expects to be able to read the data stored in the black boxes, despite the amount of time they have likely rested on the sea floor.

The plane's black boxes are believed to be nearly 23,000 feet (7,000 meters) under water. Without them, Troadec said investigators won't be able to make a definitive report of what happened.

The second and most recent search for the black boxes ended in August.

Automatic messages sent by the plane's computers just before it crashed show it was receiving false air speed readings from sensors known as Pitot tubes. Experts have said running into a violent storm at either too slow or too fast a speed at high altitudes could be dangerous.

Both the European Aviation Safety Agency and the U.S. Federal Aviation Administration ordered airlines flying Airbus jets like the one that crashed to replace their French-made Thales Pitot tubes.

The French Accident Investigation Agency said last week that the sensors are not certified to fly at temperatures below minus 40 degrees Celsius (minus 40 degrees Fahrenheit) and above 40,000 feet (12,000 meters), and recommended new international safety standards.

Investigators have insisted that the crash was likely caused by a series of failures and not just the Pitot tubes.

The new February search is estimated to cost 10 million euros, and will be jointly financed by Airbus and Air France, Troadec said. The U.S. Navy and the National Transportation Safety Board will help, along with accident experts from Britain, Germany, Russia and Brazil and private companies.

Bouillard said that death for the 228 victims probably came about five minutes after Flight 447 ran into trouble.

He said a reading of the automatic messages emitted by the plane suggests that the plane hit the water around 5 minutes after the problem was alerted. The plane fell 35,000 feet (11,000 meters) in that time -- 7,000 feet (2,000 meters) a minute -- meaning it is unlikely anyone survived the impact, he said.

The BEA has said it is examining an emergency distress call from another Air France flight that ran into trouble on the same route in November to help explain why the June flight went down.

French newspaper Le Figaro reported earlier this month that pilots on Air France Flight 445 made a distress call when the plane was just 10 nautical miles from the area where the ill-fated jet went down months earlier.

Troadec said that the data from the flight recorders of Flight 445 has been lost. One of them was automatically recorded over when the plane flew to a new destination and the second was not properly formatted.

The BEA will study what happened by interviewing the crew and passengers, he said.

Air France crash search to resume end February
5 February 2010

PARIS, Feb 5 (Reuters) - International search teams will be sent to the Atlantic later this month to try to find wreckage from an Air France airliner that crashed into the sea last year killing all 228 people aboard, French officials said on Friday.

Three specialised search vessels, equipped to survey the rugged sea bed at depths of up to 8,000 metres (26,250 ft), will be dispatched to search an area off the coast of Brazil of some 1,500 square km (580 sq miles).

"Our aim is for the searches to begin at the end of the month of February," said a spokeswoman for BEA, the authority in charge of investigating air accidents.

Air France flight AF447 between Rio de Janeiro and Paris crashed into the sea on June 1, 2009, killing all aboard.

A search last year found several pieces of wreckage and 50 bodies but the black box flight recorders, which could help explain the disaster, have not been recovered and the causes of the crash remain unexplained.

Two French judges are investigating the crash and victims' families have filed civil suits alongside the criminal case for "involuntary manslaughter and injury".

Investigators launch euro10 million search effort for Air France Flight 447 in Atlantic
17 February 2010

LE BOURGET, France (AP) - A new euro10 million ($13.73 million) international search for the remains of Air France Flight 447 will begin in mid-March, nearly nine months after the passenger jet crashed in the Atlantic depths, France's chief air accident investigator said Wednesday.

The search plan, involving U.S. and Norwegian ships, covers some 770 square miles (2,000 square kilometers) of sea, said Jean-Paul Troadec, chief of the BEA investigation agency. He said the approximately four-week search is the most expensive and biggest operation his agency has ever conducted and "one of the most complex undersea operations ever."

Troadec said the first search efforts after the June 1 crash, which killed 228 people, "were not fruitful." Since then, "the investigation has stalled," he said, without further information from the crash site, including from the black box flight recorders that would provide crucial information on what went wrong. The black boxes have not been found.

"I think we have good chances" to find the black boxes, he said, a "largely above 50 percent" chance. But it will be tough, he added. "First we have to find the haystack, then we look for the needle."

The BEA chief initially said the search would begin within days, then clarified to say it would begin in mid-March, depending on weather, and materials would be put in place within days.

Families of victims of Air France Flight 447 have welcomed the new search effort.

John Clemes, whose brother was among the fatalities in the June 1 crash of the plane en route from Rio de Janeiro to Paris, says the search plan has "raised our hopes." It was shared with the families Wednesday before the BEA presented it at a news conference.

"Our one regret is that it took so long" to resume searching that was halted last summer, Clemes told The Associated Press.

Troadec said the search site includes depths of up to 4,000 meters (13,120 feet).

The new search will be jointly financed by Airbus and Air France. The U.S. Navy and the National Transportation Safety Board will help, along with accident experts from Britain, Germany, Russia and Brazil and private companies.

The lifespan of the so-called "pingers" attached to the black boxes is only about a month, but officials say submarines and boats equipped with sonar gear can find the wreckage from the Airbus 330 even without such signals.

Investigators "said the black boxes can survive that kind of an impact and that time under water," Clemes said.

The second and most recent search for the black boxes ended in August.

Investigators have insisted that the crash was likely caused by a series of failures, but that they won't know definitively without the black boxes.

Investigator says third phase of Air France crash search delayed by weather, other factors
11 March 2010

PARIS (AP) - The search for the black boxes of an Air France flight that crashed in the Atlantic Ocean while flying from Rio de Janeiro to Paris has been delayed by weather conditions and trouble getting a search ship to Brazil, officials said Thursday.

In a statement, the French accident investigation agency BEA blamed "administrative and technical difficulties" along with the poor weather conditions for the delay in starting the third phase of the search, which was supposed to have begun last month.

The agency said it would provide further information on the search on Monday. Flight 447 crashed on June 1, killing all 228 people aboard, and the reason remains unknown.

Two vessels are to take part in the euro10 million ($13.73 million) third phase of the search for wreckage from the Airbus 330 in the mid-Atlantic.

One of the vessels, the Anne Candies, had its departure from the United States delayed by "administrative and technical difficulties," the agency said. "The beginning of the sea search operations has been put back accordingly," the agency noted, without saying for how long.

The delay is likely to be a matter of "several days," said Martine Del Bono, a spokeswoman for the agency.

Del Bono said the Anne Candies had left Louisiana several days late but was now on its way to Recife, Brazil, where it is to meet up with the second search vessel, Seabed Worker.

Last month, the lead investigator said there was a "good chance" the latest search would locate the black box flight recorders to provide crucial information on what went wrong.

The latest search plan -- involving U.S. and Norwegian ships, investigators and scientists -- covers 770 square miles (2,000 square kilometers) of sea.

The four-week search is the biggest, most expensive operation the BEA has conducted and one of the most complex undersea operations ever, Jean-Paul Troadec, chief of the BEA investigation agency, told reporters last month.

The new search is being jointly financed by Airbus and Air France, and it comes after original search efforts last year cost about euro9 million.

The U.S. Navy and the U.S. National Transportation Safety Board will help, along with accident experts from Britain, Germany, Russia and Brazil, and private companies.

Brazilian judge awards $1M in Air France suit

A Brazilian judge has ordered Air France to pay the equivalent of more than $1 million in damages to the family of one of the victims of last year's crash that killed more than 200 people, officials said Friday.

Judge Mauro Nicolau Junior ordered Air France to pay 2 million reals ($1.2 million) in damages to the family of Marcelle Valpacos Fonseca, a Brazilian state prosecutor who was among the 228 people who died in the Rio-to-Paris crash, said a statement released by the Rio de Janeiro State Judiciary.

Osmar Maduro, an Air France spokesman in Brazil, told The Associated Press that the airline would not comment on the judge's ruling.

Air France's insurer, AXA, said in a statement that it would appeal the ruling because it was not made by the compensation body established by Brazil's government.

An advocacy group in France reacted Friday by announcing that it would seek equal compensation for French victims of the crash.

Air France Flight 447 crashed in the Atlantic Ocean off Brazil's northeastern coast on June 1, 2009. All those aboard were killed.

The first two search operations after the crash turned up 50 bodies and about 1,000 pieces of wreckage _ but not the black-box flight recorders that could give clues as to what made it plunge into the sea during thunderstorms at night. The boxes are believed to be somewhere on the ocean floor at extreme depths.

The third, French-led search operation _ initially scheduled to begin last month _ was delayed by weather conditions and trouble getting a search ship to Brazil, the French accident- investigation agency said Thursday.

The latest operation is expected to cover 770 square miles (2,000 square kilometers) of ocean in four weeks. It is the biggest, most expensive search BEA has conducted and one of the most complex undersea operations ever, BEA chief Jean-Paul Troadec told reporters last month.

Latest Air France crash search proves inconclusive

PARIS, April 23 (Reuters) - An international search to locate the black box recorders from an Air France plane that crashed near Brazil last year killing 228 people has so far proved inconclusive, French officials said on Friday.

Air France flight AF447 between Rio de Janeiro and Paris crashed into the sea on June 1, 2009, killing everyone on board. The families of the victims had hoped the plane's black box recorders will be found in order to shed light on the disaster.

France's BEA body -- the authority in charge of investigating air accidents -- added it would continue with the search and issue an update on the situation on May 4.

A search last year found several pieces of wreckage and 50 bodies but the black box flight recorders have not been recovered and the causes of the crash remain unexplained.

AF447 Francia emitirá un nuevo informe sobre el accidente del vuelo Río-París de Air France el próximo 4 de mayo

EuropaPress

Af447La Oficina de Investigaciones y Análisis (BEA, según sus siglas en francés), organismo encargado de la investigación del accidente del vuelo París-Río de Air France emitirá un nuevo informe el próximo 4 de mayo, una vez concluya la tercera fase de la búsqueda de las cajas negras que por el momento sigue siendo "infructuosa".

La BEA indicó que la búsqueda submarina en la zona delimitada unos 3.000 kilómetros se completará prácticamente este fin de semana. Hasta el momento, en los 2.800 kilómetros revisados no se ha encontrado resto alguno de las cajas negras del avión.

Los tres barcos equipados con sonar que participan en la búsqueda han realizado un total de 40 inmersiones en condiciones meteorológicas favorables sin obtener ningún resultado.

Según informó hoy el diario ’Le Figaro’, el presupuesto para esta nueva campaña de búsqueda ya se ha agotado por lo que no está claro que continúe la búsqueda.

El secretario de Estado de Transportes de Francia, Dominique Bussereau, dijo hoy que ha pedido a la BEA que continúen con la búsqueda para tratar de localizar los restos del avión de Air France, que cayó al Atlántico el 1 de junio de 2009, y en el que murieron 228 personas, que permitan esclarecer las causas del accidente, que por el momento se desconocen.

El segundo informe de la BEA sobre el accidente recomendaba "cambiar los criterios para la certificación" de las sondas de velocidad --conocidas como ’pitot’-- de la marca francesa Thales en los A330 y A340 por otras del fabricante estadounidense Goodrich, ante las dudas sobre la fiabilidad de las mismas.

ÚLTIMA OPORTUNIDAD PARA ENCONTRAR LAS CAJAS.

Para Bussereau la tercera fase de la investigación, que aún no ha finalizado, supone la última oportunidad para localizar las cajas negras del avión.

La BEA dio por concluidas las tareas de búsqueda de las cajas negras el 20 de agosto de 2009, que no permitieron su localización, pero sí algunos restos del avión. En sus primeras fases, los expertos analizaron unos 1.000 fragmentos del avión.

Los trabajos efectuados con los equipos de asistencia acuática durante la segunda fase de la investigación permitieron completar la exploración en un radio de 75 kilómetros, tomando como referencia el último mensaje enviado por el aparato sobre su posición, lo que permitió encontrar trozos del fuselaje y de la cola y recuperar 51 cuerpos.
Durante estas tareas, la señal emitida por las balizas de las cajas negras no pudo detectarse. Cuando están sumergidas, emiten durante un mínimo de 30 días con una frecuencia de 36.5 megaherzios y un impulso por segundo, por lo que si están a gran profundidad los micrófonos sumergidos no captan fácilmente la señal. En la tercera fase la nueva búsqueda se realiza a 4.000 metros de profundidad.

Black boxes of Rio-Paris air crash plane found

The French navy has located the black box flight recorders from an Air France jet that crashed in the Atlantic in June last year, killing 228 people.

The recorders have been localised "with a margin of error" of three nautical miles (five kilometres), according to General Christian Baptiste, France's deputy defence ministry spokesman.

And while the news could reassure relatives of the victims still waiting for an explanation of the cause of the disaster, the spokesman said there was no guarantee the recorders would be brought to the surface.

"This does not mean we are going to retrieve the black boxes because they are not giving off a signal any more and the zone where they are is very rugged terrain," General Baptiste said.

The French navy started a new operation on Monday to find the black boxes.

The crash of flight AF 447 was the worst in Air France's 75-year history.

On June 1, the Airbus A330 came down in the Atlantic as it was flying from Rio de Janeiro to Paris, resulting in the deaths of all passengers and crew on board.

The cause of the accident is still unknown, but investigators say malfunctioning airspeed probes on the aircraft were a factor.

The flight data and cockpit conversations recorded on the black boxes are crucial to determining the circumstances of the crash.

A three-month search last year by a French navy submarine and sonar-equipped ships failed to locate the devices.

A private memorial was held for the victims in Rio de Janeiro in November.

In the same month, relatives of eight of the victims filed lawsuits against Air France seeking damages.

The lawsuit filed in the US state of Illinios alleges negligence and products liability on the part of Airbus and the makers of various instruments used on the flight.

"As a direct and proximate result of the defendants' negligence, the subject aircraft crashed into the Atlantic Ocean on June 1, 2009, killing plaintiff's descendants, causing severe terror and pain prior to impact, and resulting in both personal and pecuniary injuries," the lawsuit said.

Air France Crash Probe Gets Boost as Signal Detected

May 6 (Bloomberg) -- Signals emitted by “black boxes” from the Air France plane that plunged into the Atlantic last year have been identified in data gathered in the weeks after the crash, boosting the chances of retrieving information regarded as vital in explaining why the accident occurred.

Computer analysis detected sounds believed to be from the black-box “pingers” in recordings made by the Emeraude nuclear submarine, French Defense Ministry spokesman Christian Baptiste said today in Paris. While the findings will refine the search area, locating the equipment remains a challenge, he said.

“We have an area the size of Paris, we’re looking for something the size of a shoe box, and we have a terrain that resembles the Andes,” Baptiste said at a news conference.

Air France Flight 447 crashed on June 1 en route from Rio de Janeiro to Paris, killing all 228 people on the Airbus SAS A330. The location suggested by the new analysis is 40 nautical miles (74 kilometers) west of the area being searched by France’s BEA air-accident investigation bureau, Baptiste said.

The BEA will shift its search to the zone identified by the recordings starting tomorrow morning, it said in a statement. The area measures “a few dozen square kilometers” and is located about 200 nautical miles northwest of the Brazilian archipelago of Sao Pedro and Sao Paulo.

Speed Sensors

Since the crash, salvage teams have pulled about 1,000 pieces of debris and 50 bodies from the ocean, and the BEA last month began a third search for the flight recorders. No definitive reason has yet been presented for the accident, though early studies indicated that the plane flew into poor weather with speed sensors that weren’t properly functioning.

The Emeraude’s recordings were made in an initial search phase in the month after the crash, during which the black boxes were expected to emit signals before running out of power. The pinger traces were revealed after defense-electronics specialist Thales SA developed software to improve processing of the data.

“If confirmed, these developments are excellent news because they will be a determining factor for the search efforts and for the truth to be established,” Paris-based Air France said in a statement today.

The potential breakthrough came just as BEA investigators had begun scaling back the hunt after failing to find any trace of the cockpit data and voice recorders three weeks into their third search operation.

In the latest phase, two sonar-equipped vessels began scanning the mountainous Atlantic seabed last month after oceanographers reduced the previous search area by 90 percent with the help of satellite data on ocean currents.

French Transport Minister Dominique Bussereau had asked the BEA to persist with the search April 23, after the investigators said it was unclear whether there was a scientific case for further operations.

One of the BEA’s two search vessels, the Anne Candies, was also withdrawn from the operation after the U.S. Navy recalled sonar equipment and a robot submarine carried by the craft.

Very good news. I'm surprised. Hopefully they'll be able to bring them to the surface.

just an idea
IF it was a terrorist attack the plane was destroyed over the best place to do it.
It's almost impossible to find it.

The pings are still working after all this time?

Probably not. But the visual and other data collected by the SAR and the Navy after the crash together with the reverse-drift sea current data is being used. It's very unreliable however, as the surface debris was scattered and almost fully submerged, the weather was bad in the days after the crash, making it very hard to pinpoint.

I hope that they do find it and work out what happened, and until then, fly Boeing.

Nope, pings were "detected" from earlier signal recordings from data collected within the month after the crash.

And Boeing hasn't have any crashed to date? or do you switch between them every time there is a crash.

Also thanks to the encrypted automated messages, I think they (investigators) have a pretty good idea of what happened. The boxes (if found) will most probably on confirm their theory and reveal certain details but I think they got the basic thing right already.

btw, looks like they are renewing efforts to get the boxes.

France considers new search of AF447 black boxes

12/07/2010

France may order another deep water search for the black boxes of an Air France jet that crashed in the Atlantic last year, the junior transport minister said Monday.
Dominique Bussereau said he would await the latest findings of the BEA air accident investigation agency, due in September, to decide on a new search operation.


Flight 447 between Rio de Janeiero and Paris went down in the Atlantic roughly midway between Brazil and Senegal on June 1, 2009, with 228 people on board, the worst crash in Air France's history. "I will be receiving in early September some facts from the BEA that will allow me to decide on a possible new search," said Bussereau at an event with the crash victims' families.


A third search of the ocean floor to try to locate the black box flight recorders ended in failure in May.


"The analyses of the three search operations show that there are areas where we do not have to return, areas where we could perhaps return because something may have been overlooked and areas where we have not been at all," said Bussereau.
"We will be examining this over the summer and after that, decide whether or not there will be a fourth search," he said.


BEA director Jean-Paul Troadec said he was in favour of a fourth attempt to try to find the black boxes and the plane wreckage, saying this was "crucial" for the investigation.
The families of the victims also called for a fourth search. Crash investigators have acknowledged in previous reports that Airbus 330-200's airspeed monitors were faulty, but maintain this could not have been the sole cause of the disaster.

A series of automatic error messages were emitted by the on-board flight computer shortly before the plane disappeared from radar.

***

my regrets are not on the efforts to recover the boxes or changes to the pitot tubes but a lack of will from the regulation boards regarding using more advanced tech on board planes...A plane should never "go missing" in this age of technology and (off topic here but)there are lots of "near misses" in our crowded skies, "intruders" on runways, etc that will (unfortunately) need a major disaster for someone to take action.
