What happened
During the initial climb phase of the flight, the aircraft experienced significant issues maintaining altitude. Shortly after leaving the ground, the plane entered a stall and subsequently crashed, resulting in a post-impact fire. While all 10 skydivers on board managed to escape the wreckage, one individual sustained injuries during the event. The pilot was killed in the accident.
Findings
The investigation concluded that the primary reason for the accident was a stall occurring during the climb, which was attributed to inadequate preflight preparation by the pilot. Several contributing factors were identified regarding the aircraft's condition and operation:
- The pilot lacked sufficient familiarity with the aircraft type.
- There was a failure to abort the takeoff sequence despite developing issues.
- The crew failed to maintain the necessary flying speed.
- The aircraft was improperly loaded, resulting in a center of gravity positioned approximately 2.5 inches aft of the allowable limit.
- The total weight exceeded the maximum gross weight by 953 pounds.
- Maintenance and inspection protocols were found to be inadequate.
- Mechanical issues were noted, specifically a failure within the ignition system involving the spark plugs.
- An incorrect grade of fuel was used in the engine.
- The takeoff was attempted from a runway strip measuring only 2,000 feet.
