NTSB Narrative Summary Released at Completion of Accident

During climb-out from the departure airport, the pilot noticed the engine "felt off balance" and began to "misfire." The pilot initiated a return to the airport, and shortly thereafter the engine "backfired" and lost all power. The pilot initiated a forced landing, during which the airplane impacted trees and was substantially damaged. Examination of the engine revealed that a helicoil was cross threaded in the number 3 cylinder head, and metallic particles were adhered to the cylinder head and top of the piston. Thirteen days earlier, the pilot reported difficulty clearing one of the spark plugs, and he removed the number 3 cylinder bottom spark plug as a result. A mechanic then cleaned the spark plug hole, assured there were no steel particles in the cylinder, replaced the helicoil, installed a new spark plug, and ran the engine. The mechanic who installed the helicoil was non-certificated, and at the time the work was performed, a certificated mechanic was not present. According to Textron Lycoming Service Instruction No. 1043A, if a spark plug Helicoil insert replacement is performed with the cylinder assembled on the engine, "some provision must be made for preventing the aluminum shavings from entering the combustion chamber."

NTSB Probable Cause Narrative

The improper installation of the helicoil by the non-certificated mechanic, and the inadequate inspection of the installation by the certificated mechanic.
