- Lack of visibility due to the night,
- The aircraft was not properly aligned on the approach path,
- The crew failed to follow the published approach procedures,
- The crew failed to pass over the outer marker, causing the aircraft to follow an erratic approach trajectory,
- The crew switched their seats as the captain was seating in the right front seat and the copilot in the left front seat, which is prohibited in such operations,
- The radio altimeter alarm failed to sound due to wrong settings,
- The aircraft banked left to an angle of 48° and nosed down to an angle of 24° just before final impact.
