What happened
During a descent toward Abuja-Nnamdi Azikiwe Airport, the flight crew encountered challenging meteorological conditions, including heavy rainfall, low cloud ceilings, and significant turbulence. Because the Instrument Landing System (ILS) was not properly calibrated for use, the crew opted to execute an approach using VOR/DME navigation.
During this maneuver, a misunderstanding of the VOR station location led the crew to initiate the final approach phase earlier than intended. As a result of the premature descent, the aircraft type struck the side of a mountain approximately 12.2 km before reaching runway 22. The accident resulted in three fatalities and two survivors.
