What happened
During a nighttime approach to Iligan-Maria Cristina Airport, an aircraft encountered restricted visibility due to darkness. While maneuvering toward the runway, the plane collided with the side of Mt Gurain, situated approximately 16 km south of the threshold for runway 02.
The accident resulted in 15 fatalities, with no survivors reported among the occupants. The impact occurred during the approach phase of flight.
Findings
Investigations into the crash determined that the primary factor was controlled flight into terrain. While weather conditions were generally considered good, the lack of visibility at night contributed to the crew's inability to avoid the mountain slope.
