What happened
The accident occurred during the initial takeoff climb phase of a test flight. The aircraft was operating under conditions where it needed to clear obstacles located 584 feet from the end of the runway. This mission represented the first flight following a complete engine overhaul.
According to the pilot's account, the engine began to lose power when the aircraft reached an altitude of approximately 50 feet above ground level. At this specific point, the aircraft was positioned near the intersection of runways 7 and 25. This location left approximately 1,400 feet of remaining runway plus a 550-foot overrun area available for stopping.
The pilot stated that after completing the emergency checklist procedures, it became apparent that engine power had reduced even further. Despite these mechanical issues, the takeoff was continued in an attempt to clear the obstacle. Ultimately, the aircraft contacted the power lines.
The investigation
Post-accident examination of the engine and propeller revealed no visible abnormalities. This physical inspection suggested that catastrophic mechanical failure might not be immediately evident from external visual checks.
Witness accounts provided conflicting information regarding the nature of the power loss. Two witnesses stated they heard no interruption in engine power during the event. One witness noted that the aircraft bounced on the runway during the takeoff roll and that the climb was initiated later than expected. These observations suggest that pilot technique or timing may have played a role alongside the reported mechanical issues.
Findings
The combination of reduced engine performance during a critical phase of flight and potential delayed rotation contributed to the inability to clear the power lines. The initial bounce on the runway may have consumed valuable altitude or speed necessary for obstacle clearance.
