The investigation cited the pilot's lack of night flying experience, the co-pilots misreading of the emergency procedures related to the landing gear issue, and the aircraft's poor mechanical condition as contributing factors to the accident.

Additionally, the F27's maintenance log, which was handed to the pilot before takeoff, showed a series of mechanical defects including lacking an inertial guidance system, poor UHF radio performance, a VOR receiving unit with inadequate reception, a malfunctioning radar altimeter and a worn front landing gear indicator light switch.
