Impressionnante solidité de l'A320.

Exactement comme dans le cas de l'accident précité du vol BA038. Et on se souvient qu'il y avait des pilotes d'une certaine compagnie bien connue, paraît-il, qui, qui dans leur fauteuil, allaient contre la télémétrie, les témoignages officiels des pilotes, l'enqûête officielle de l'AAIB, et l'enquête interne de la Cie. BA ! En foi de quoi ? Dans quel but ?
Bien sûr, peu de chances pour qu'on voie cela sur ce Forum ! Et c'est bien !
Sans manque de respect aucun, je ne partage pas votre point de vue. Et pour cause.Poncho a écrit:
Bonsoir,
Je pense qu'il n'est pas nécessaire ici de rappeler des joutes qui ont eu lieu ailleurs et qui ont laissé des traces... et qui ont conduit à la mise en place de cette structure...
Dans quel but le rappeler ? Pour poursuivre la discussion ?
DATE:18/01/09. SOURCE:Air Transport IntelligenceHudson crash: A320's engines lost power simultaneously
By David Kaminski-Morrow

Initial flight-recorder information from the US Airways Airbus A320 which crashed into New York's Hudson River shows that both engines lost power simultaneously, and that the aircraft reached a maximum altitude of 3,200ft.
The National Transportation Safety Board has disclosed preliminary data from the two recorders on board the aircraft, retrieved after the airframe was lifted from the river.
Cockpit-voice recorder information identifies the first officer as the flying pilot at the beginning of flight 1549 to Charlotte on 15 January.
The CVR has 30min of "excellent quality" data, says a spokeswoman for the NTSB, adding that the pre-flight checks, taxiing and take-off from New York LaGuardia Airport were normal.
Flight 1549 was cleared for take-off from runway 04 at 15:24:54, and instructed to make a left turn to heading 360°. One minute later, LaGuardia tower instructed the crew to contact New York terminal radar departure control.
At 15:25:51 the pilot contacted the departure controller, advising that the jet was at 700ft and climbing to 5,000ft, and the controller cleared the aircraft to 15,000ft. The aircraft was also subsequently given an instruction to turn left, heading 270°.
But around 90 seconds after take-off, says the NTSB spokeswoman, the CVR records the captain remarking about birds and, one second later, there is a "sound of thumps" and the engine noise starts "rapidly decreasing". At this point the captain acknowledged that both engines had lost thrust and took control of the aircraft.
The flight-data recorder - which also has good-quality information, says the spokeswoman - reveals that the A320 reached a maximum altitude of 3,200ft and that there was a simultaneous loss of power in both engines.
CVR information shows that the crew began reading appropriate checklists in a bid to restart the engines but were unsuccessful.
The captain declared a 'Mayday' to air traffic control and advised that they were returning to LaGuardia.
There was a discussion with air traffic control about a possible diversion to Teterboro Airport but the crew began to conclude that neither airport could be reached and the captain made a public-address announcement to brace for impact about 90 seconds before the A320 ditched in the Hudson River. The ground-proximity warning system activated and the recording ended with the water impact, about 3.5min after the loss of engine power.

J'ai lu un article FAA et CFMI qui dit que le réacteur est testé pour les chocs d'oiseaux et qu'il ne doivent perdre que 45% de puissance.
Le probleme de l'A320 US Airways et que les deux reacteurs ont perdu la totalité de leurs puissance.
Suite a cette accident vont ils revoir les normes au choc d'oiseaux...?
Crash plane had engine trouble days earlier: report
NEW YORK, Jan 19, 2009 (AFP)The same US Airways plane that crashed into the Hudson River last week had engine trouble two days earlier, CNN television reported Monday.2009 AFP
L'Airbus de l'Hudson avait eu un ennui de moteur deux jours avant l'accident
NEW YORK, 19 jan 2009 (AFP)L'Airbus A320 de la compagnie US Airways, qui a amerri d'urgence jeudi sur l'Hudson à New York, avait eu un problème de moteur deux jours avant l'accident, a indiqué lundi la chaîne de télévision CNN sur son site internet.
Investigators confirm bird strike, past compressor problem on ditched A320.
Wednesday January 21, 2009
Attendons un AD ?The US Airways A320 that ditched safely in New York City's Hudson River following a bird strike last week previously had suffered a compressor stall on one of its engines, investigators said.
Normal. On peut se féliciter de la présence plus active depuis plusieurs mois, déjà, du NTSB dans ces enquêtes officielles ! Nous en connaissions les raisons, mentionnée à plusieurs reprises par ailleurs ! La FAA est sous pression, aussi !A US National Transportation Safety Board spokesperson told reporters Monday that maintenance records of the nearly-10-year-old aircraft revealed the stall occurred on Jan. 13. The pilot on that flight will be interviewed by investigators.
Oui, "perte de puissance simultanée dans les deux moteurs" du biréacteur ! Exactement comme dans le cas du vol BA038, lors du crash du B777-200ER de BA à LHR, en janvier 2008 ! Et, dans les deux cas, ostensiblment pour des "causes" d'origine externe aux moteurs. Pas de panne-moteurs ; "perte de puissance-moteurs" ! Détail très important, et très précis.NTSB also said that the flight data recorder confirmed that the aircraft lost power in both engines simultaneously following the bird strike.
Cette information se répète et se confirme, donc."The captain makes a radio call to ATC calling mayday and reports that they hit birds, lost both engines and were returning to LaGuardia," the Safety Board's Kitty Higgins told reporters (ATWOnline, Jan. 19). She added that the FDR showed that the aircraft reached 3,200 ft. before losing power.
Promptitude de cette indemnisation !Meanwhile, US has sent $5,000 to each of the 150 passengers onboard Flight 1549, which was scheduled to fly to Charlotte, to compensate them for lost luggage.
The A320, sans (sic! "sans" : without) the left engine, was lifted from the Hudson and taken to a New Jersey marina over the weekend. NTSB will disassemble the aircraft for further examination? while a search for ther other engine continues.
