Chitna Airport
Aircraft Accident/Incident Report

Chitina, Alaska 99566
Saturday, May 3, 1997 19:00 AKD

NTSB Narrative Summary Released at Completion of Accident

The pilot was departing in a homebuilt airplane from a remote airstrip. After departure, the airplane climbed to about 250 feet above the ground, and then the engine suddenly lost power. The pilot performed a 180 degree turn back toward the runway, but landed in rough terrain, just short of the runway. The engine was overhauled 5 hours before the accident, and one piston was replaced with an oversize piston. Following the accident, an examination of the engine revealed the oversize piston was seized in the cylinder. The seized piston was found to be the same size as the cylinder bore.

NTSB Probable Cause Narrative

improper overhaul of the engine, which resulted in a seized piston and resultant loss of engine power. Rough terrain in the emergency landing area was a related factor.
