Probable cause

Engine failure due to failure of the gas producer and power turbine assemblies. A factor in the accident was the lack of suitable terrain for the forced landing.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Object - tree(s)

Analysis

When power was reduced to begin initial descent for approach and landing the engine lost power and the pilot performed a forced landing on a road. The road had a 4% upgrade and curved to the right. During the rollout the outboard end of the right wing struck a tree damaging the wing carry through spar. Metallurgical testing revealed the cause of the power loss to be failure of the gas producer turbine.
