Air Asia - Informe final del accidente del A320 PK-AXC 29/12/14
« Respuesta #40 : 01 de diciembre de 2015, 23:07:55 »
Las autoridades de Indonesia han publicado el informe final del accidente de Air Asia en diciembre ppdo.

No lo he leido completo (y no es una lectura facil) pero da la impresion de ser una serie de errores que terminaron con una tripulacion desorientada y sin saber como reaccionar, aparentemente.

"There is not much to say about most airplane journeys. Anything remarkable must be disastrous, so you define a good flight by negatives: you didn't get hijacked, you didn't crash, you didn't throw up, you weren't late, you weren't nauseated by the food. So you're grateful." Paul Theroux

Resumen

The cracking of a solder joint of both channel A and B resulted in loss of electrical continuity and led to RTLU (rudder travel limiter unit) failure. The existing maintenance data analysis led to unresolved repetitive faults occurring with shorter intervals. The same fault occurred 4 times during the flight.

The flight crew action to the first 3 faults in accordance with the ECAM messages. Following the fourth fault, the FDR recorded different signatures that were similar to the FAC CB‟s being reset resulting in electrical interruption to the FAC‟s.

The electrical interruption to the FAC caused the autopilot to disengage and the flight control logic to change from Normal Law to Alternate Law, the rudder deflecting 2° to the left resulting the aircraft rolling up to 54° angle of bank.

Subsequent flight crew action leading to inability to control the aircraft in the Alternate Law resulted in the aircraft departing from the normal flight envelope and entering prolonged stall condition that was beyond the capability of the flight crew to recover.
