Aircraft collision with trees and power lines during takeoff

No fatalities • Mobile, United States of America • Takeoff (climb)

An aircraft carrying ten parachutists struck trees and power lines during its takeoff roll from a short runway area.

What happened

During a takeoff attempt from a 2,000-foot open field, an aircraft carrying ten passengers (parachutists) collided with power lines and trees. The incident occurred while the plane was operating from a limited-length runway area. According to the pilot, the engine experienced an unexpected reduction in power during the takeoff roll, though some power was reportedly recovered before the impact. However, the aircraft was unable to clear the obstacles.

Findings

Conflicting accounts were provided regarding the engine's performance. While the pilot reported an unsolicited rollback in power, the chairman of the jump club stated that no irregularities in engine operation were noted during the flight. Witnesses at the scene observed winds of 12 knots originating from the northeast, which would have provided a quartering tailwind during the departure. Notably, the maximum demonstrated crosswind for this aircraft type is 12 knots. A post-accident inspection of the aircraft revealed no evidence of mechanical failure or system malfunctions.

Probable cause

The cause remains uncertain due to conflicting reports regarding engine power loss, though wind conditions were at the aircraft's maximum demonstrated crosswind limit.
