AF447 - tilsvarende hendelse med tap av airspeed i juli åpner for ny debatt

PARIS (Reuters) - An Air France (AIRF.PA) flight in July suffered similar technical problems to a jet that crashed into the Atlantic two years ago, French media reported on Tuesday, reigniting a debate over the disaster's causes.
Air investigators told France's Le Figaro newspaper the details of the latest incident involving one of the company's Airbus (EAD.PA) jets might make them think again about what made flight AF447 crash off the coast of Brazil in 2009.
Investigators have so far stopped short of explicitly blaming the pilots for the 2009 disaster, which killed 228 people -- but their reports have highlighted mistakes they said were made on the flight deck.

Pilots' unions and Air France insist the faulty flight equipment was mostly to blame. Both Airbus and Air France are facing criminal probes in France and lawsuits on both sides of the Atlantic.
In its online edition on Tuesday,
Le Figaro said it had obtained a report on an incident on an Air France flight from Paris to Caracas in July.
"This incident certainly takes on a particular importance in the light of the Rio-Paris accident," a source close to the investigation was quoted as saying.
"It will help us to understand whether there was a problem with the Airbus or in the training received by flight crew in manual aircraft handling at high altitude," the source said.
Two crew were injured in the July incident which occurred on an Airbus A340, but there were no victims, Le Figaro said.
The BEA confirmed it had opened an investigation,
but refused to say whether the flight experienced problems similar to the 2009 crash of the Airbus A330.
Le Figaro said the report showed that like AF447, the A340 hit severe turbulence while cruising at 35,000 feet, and accelerated rapidly, causing the autopilot to switch itself off.
The jet then climbed sharply and began to lose speed, as with AF447, but managed to remain in flight thanks to a reduction in the turbulence and the rapid response by the crew, the newspaper said.
Air France was not immediately available to comment.
An airline security source close to Airbus told Le Figaro the July incident was clearly complex, and would revive speculation over the aircraft-maker's role in the 2009 crash.
The BEA air accident authority has said the pilots lacked training to handle the freezing of speed sensors and failed to discuss stall alarms as the Airbus jet plummeted 38,000 feet.
Air France disputes this and says instruments went haywire.

BEA, the French civil aviation accident agency, has announced that it has just formed the Human Factors working group, whose creation was announced in July, as it continues its investigations in to the loss of the Air France A330 that crashed into the Atlantic in 2009.

The group comprises three BEA investigators specialising in human factors, a human factors aviation consultant, a psychiatrist specializing in risk analysis, an A330 test pilot and a type-rated A330 pilot.
The agency said that the group’s objective will be analyse “all aspects connected to the conduct of the flight” including “Crew actions and reactions during the last three phases of the flight described in the third Interim Report, in particular in relation to the stall warning, Cockpit ergonomics and Man-machine interfaces”.
