Aircraft Accident/Incident Report

Valdez, Alaska 99686
Monday, March 30, 1998 14:20 AST

NTSB Narrative Summary Released at Completion of Accident

The pilot, who also held a mechanic certificates, had overhauled the airplane engine. The accident flight was the first flight since the overhaul. About 5 minutes after departure, the engine lost power. The pilot restarted the engine, but it only ran another 45 seconds before stopping again. The pilot selected an emergency landing area on a highway, but had to slip the airplane to avoid several vehicles on the highway. The airplane collided with a power line about 25 feet above the ground, and then descended to the ground. Disassembly of the engine revealed all the engine cylinders were scored. The pilot had installed chrome cylinders, and during the assembly, he applied a coating of light grease to each engine cylinder bore. According to an FAA inspector, the engine cylinders required an application of a thicker grease than what was used by the pilot.

NTSB Probable Cause Narrative

The owner/pilot mechanic's improper overhaul of the engine, and lack of proper lubricating cylinder grease. A factor in the accident was the lack of a suitable area for a forced landing.
