Aircraft Accident/Incident Report
Carthage, North Carolina 28112
Monday, June 20, 2011 10:00 EDT
NTSB Narrative Summary Released at Completion of Accident
According to the pilot, during the turn from the base leg to final approach, the engine experienced a partial loss of power. He performed a forced landing into some small trees because he knew he could not glide the airplane to the runway. The airplane sustained substantial damage to the wing spars. A postaccident examination revealed that a spark plug was backed out of the No. 1 cylinder and was suspended from the electrode wire. The pilot reported that he had changed the engine spark plugs the day before the accident and that he may have cross-threaded one of them.
NTSB Probable Cause Narrative
A partial loss of engine power due to the pilot’s improper installation of the engine’s No. 1 cylinder spark plugs.
