air france A330 crash

i think it's just explosive decompression - like this one
BOAC Flight 781 - Wikipedia, the free encyclopedia
and this one
Aloha Airlines Flight 243 - Wikipedia, the free encyclopedia

exploded in mid air - probably due to metal fatigue or structural damage or stress limit was reached during that storm. it explains why there was no mayday. just my 2 cents.

latest news: Northwest Jet Suffers Similar Malfunctions to Air France Flight

Northwest Jet Suffers Similar Malfunctions to Air France Flight - WSJ.com

It says a Northwest Airlines A330 jet traveling from Hong Kong to Tokyo last Tuesday suffered a series of equipment and computer malfunctions strikingly similar to those encountered by AF447.

A memo by one of the Northwest pilots indicated a system breakdown that prevented the crew from knowing how fast the plane was flying. The Northwest Airbus A330's crew was left without reliable speed measurements for three minutes. In addition, the computer safeguards designed to keep the aircraft from flying dangerously too fast or too slow were also impaired. Like the Air France A330 jetliner, the Northwest plane entered a storm and quickly started showing erroneous and unreliable airspeed readings.

According to the memo written by one of the crew, the twin-engine Northwest jet was cruising at 39,000 feet when it "approached a large area of rain below us." The plane's weather radar indicated only light precipitation or perhaps ice crystals straight ahead. The memo recounts how pilots were surprised to see substantial rain "streaming up the windshield" at that altitude and "the sound of the plane getting pelted like an aluminum garage door."

In the course of five seconds, according to the memo, airspeed indicators for both the captain and copilot showed a huge rollback in the plane's forward velocity. The standby indicator also rolled back. With autopilot and automatic-throttle controls disengaged, the cockpit was filled with beeps and bright warning signals indicating various system malfunctions.

According to the Northwest crewmember's account, the captain "hand flew the plane on the shortest vector out of the rain."

Airspeed indicators continued to waver, but the crew maintained the recommended steady engine settings. Once the airspeed indicators resumed functioning, "we were within 5 knots of our desired speed," according to the memo. "I think it could have been much worse," the memo writer concluded.

On Friday, A spokeswoman for Delta Air Lines said its Northwest unit is cooperating with the NTSB. Delta currently is installing new airspeed sensors, known as pitot tubes, on its A330 fleet and expects to complete the work soon. The spokeswoman declined to say if the aircraft involved in Tuesday's incident has the replacement devices. "Our flight crews have the correct procedures to operate the aircraft manually in the event of an unreliable airspeed indication," the spokeswoman said.

The Northwest pilot wrote that his flight-control computers never returned to normal during the rest of the flight to Tokyo's Narita airport.

Coping with computer problems is part of routine pilot training. But "pilots only occasionally have the chance to practice" flying a plane with major computer systems down, says John Goglia, a former NTSB member. Part of the reason is because airlines want to reduce training costs by limiting the amount of time pilots practice in simulators.

who was the Filipino on board?

another Airbus plane involved in a crash with 154 persons on board. the Yemenia IY626 crashed last june 30 in Comoros island. the A310 Airbus plane is also believed to have crashed due to the combination of extreme weather and near-total systems failure. the plane in question had actually been banned from Europe entirely because of faults detected during inspections on the Yemenia A310 in 2007. however Yemeni transport officials say the plane was thoroughly checked in May under Airbus supervision.

nevetheless, because of the commonalities in circumstance among the AF447 crash, Northwest's incident and the recent Yemeni crash, questions have been raised on the safety of Airbus planes. note: reports say that prior to AF447, not a single person had died onboard the more than 1,000 A330's and A340's in service today.

mam unofficialplayer, u seem to be an aviatrix..

and now they say the jet broke up in contact with water, not in the air. accident investigation agency said an examination of the recovered wreckage led them to believe the plane probably hit the water "in the direction of flight and with a strong vertical acceleration". they further explained that if the plane had broken up in the air, pieces of the fuselage would have been found twisted in a variety of directions. instead they showed signs of compression in one direction, resulting from the plane hitting the water on its belly.

as for the pitot tube problem, they said they had been "a factor but not the cause" of the crash.

search for the data recorders would be extended to 10 July.

student? what course are you taking up and what school?

[unofficialplayer]

there are reports that with the investigators' finding that the plane hit the water intact, on its belly, it is likely that the passengers were alive upon impact. but if they were conscious how come none of the bodies recovered was wearing a lifejacket and how come the crew seats were folded when found (this means crew did not return to them in response to an emergency)?



OT: special course ra ako gikuha. wa pa jud mahuman.

[tophat]

apil ko ha....ang pitot tubes sa airbus a330 duna man na heater to protect from icing at high altitudes...ngano kaha mao na suspect noh? sakto on the possible loss of proper air speed indicator on the cockpit...ambot lang sab. latest evidence point to mid air disintegration.
