Nappanee Municipal Airport
Aircraft Accident/Incident Report

Nappanee, Indiana 46550
Friday, July 5, 2013 12:30 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that, upon leveling the airplane at the assigned cruise altitude, he heard three loud “bangs” and that the engine oil pressure and temperature indications exceeded the gauge limits. He was unable to maintain altitude and subsequently executed a forced landing to a field. A postaccident engine examination revealed that a portion of the No. 6 piston face had separated along the perimeter due to detonation within the cylinder during operation. The No. 5 connecting rod had separated near the crankshaft journal, and the lower portion of the engine crankcase exhibited a hole immediately above the oil sump. Metallic fragments were recovered from the oil sump, oil sump screen, and oil filter. Piston fragments likely interrupted the oil flow within the engine, which resulted in the failure of the No. 5 connecting rod.

NTSB Probable Cause Narrative

The failure of the No. 6 piston due to detonation and the subsequent interruption of the engine oil flow that resulted from the piston fragments.
