What happened
During the initial climb following departure, an aircraft carrying a pilot and 16 jumpers experienced a total loss of engine power at an altitude of roughly 300 feet. Following the power loss, the aircraft type/model entered a steep left bank and transitioned into a nose-down spiral, ultimately impacting the ground. The accident resulted in 17 fatalities.
Investigations into the wreckage revealed that the aircraft, registration N551CC, was operating significantly over its maximum weight limit, exceeding the allowable mass by approximately 370 lbs. Additionally, the center of gravity was positioned one foot forward of the permitted limit. The cabin configuration had been altered by removing nine passenger seats to accommodate a larger number of jumpers, and the passengers were not wearing seat belts during the flight.
Findings
The primary cause of the engine failure was identified as fuel contamination. Analysis of the fuel tanks showed the presence of water, iron particles, and organic matter resembling brown algae. The engine fuel control contained a mixture consisting of approximately 65% jet fuel and 34% water. This contamination originated from 55-gallon drums used for refueling, which were stored in a manner that allowed rainwater to enter through the filler caps. The aircraft had a documented history of similar contamination issues.
Further investigation noted several operational and maintenance deficiencies. It was reported that the stall warning circuit breaker had been previously disengaged to avoid startling passengers, though its exact state at the time of impact could not be confirmed due to damage. The investigation also highlighted inadequate regulatory surveillance and improper management regarding the maintenance and servicing of the aircraft equipment.
