TEMPO.CO, Jakarta - Former Garuda Indonesia pilot Capt. Shadrach M. Nababan, said -based on its logbook data - that the Airbus A320-200 serving AirAsia flight QZ8501 had experienced problems as much as nine times on its auto rudder trim limiter flight control in 2014.
Three days before crashing on December 25, 2014, flight QZ8501 experienced a 'return to apron' twice, according to Shadrach.
Flight QZ8501's last transmission were revealed by the Transportation Minister Ignasius Jonan in a meeting with the Transport Commission Legislature on Tuesday, January 20, 2015, saying that the aircraft tried failed gain altitude and stalled before vanishing from Soekarno-Hatta's ATC (Air Traffic Control) radar. The plane attempted to climb from 32,000 feet to 37,000 feet between 06:17 to 06:17:54 am (Western Indonesian Time).
At 6:17:54, the plane stalled from 37,000 feet to 36,000 feet in six seconds, and to 29,000 feet in 31-seconds. At 6:18:44 am, the plane vanishes from ATC radar.
Shadrach explained that commercial planes are not allowed to do any extreme climbs in the air because it does not have the same power as fighter jets.
