What happened
The pilot reported that during the final approach phase of flight, the aircraft's engine began to surge and lose power unexpectedly. In response to this mechanical anomaly, the pilot attempted to extend the glide path to reach the runway. Despite these efforts, the aircraft touched down hard at a point short of where the touchdown was originally intended.
The investigation
Following the incident, the engine was removed from the aircraft for detailed inspection. Technicians partially disassembled the unit and conducted a test run to evaluate its performance under controlled conditions.
Findings
Despite the thorough examination and testing of the powerplant, investigators were unable to identify a specific mechanical reason for the power loss. The cause remains undetermined based on the available physical evidence.
