What happened
During a nighttime approach to Quảng Ngãi Airport, an aircraft impacted the side of a mountain approximately 20 km northwest of the airfield. The incident occurred amidst challenging weather conditions that limited visibility. During the descent, the crew did not maintain sufficient altitude, leading the plane to strike a mountain slope. The impact resulted in the total destruction of the aircraft and caused 27 fatalities among all occupants on board.
Findings
Investigations into the crash determined that the flight was being conducted under Visual Flight Rules (VFR) while the aircraft was actually operating within Instrument Meteorological Conditions (IMC). This discrepancy between the required flight rules and the actual environmental visibility was a critical factor in the loss of altitude control during the approach.
