Preliminary analysis of the flight-data recorder (FDR) from the Armavia
Airbus A320 that crashed into the Black Sea in May has ruled out fuel
exhaustion and engine problems as contributing to the accident.
Russia’s Interstate Aviation Committee (MAK) has also disclosed that
"during the last minute, the flight passed to the director mode with
the autopilot switched off". This is believed to indicate that the
autopilot had been disengaged, but the flight director was active on
the attitude director indicator displays.
MAK says the flight-data recorder contained 26h 20min of information
on eight flights conducted between 30 April and the crash on 3 May,
including the entire 1h 26min of the final flight.
MAK previously revealed that the cockpit-voice recorder contains
about 33min of audio information. This includes the beginning of the
incident and continues through the development of the situation on
board the twinjet.
The A320 had been attempting a second night-time approach to Sochi
airport in Russia after a service from Yerevan, Armenia.
Investigators studying the final flight have concluded that the
fuel on board was "sufficient for the safe completion of the flight"
and that the CFM International CFM56 powerplants "worked until the
moment of the aircraft’s impact with the surface of the water". MAK
adds the aircraft was not destroyed in mid-air.
The Armavia A320 crashed after abandoning an initial approach to
Sochi airport’s runway 06. None of the 113 people on board survived.
