Probable cause

The improper installation of an unauthorized sealant used on the oil ressure screen housing gasket contaminated the oil and restricted the flow of oil through the main bearings causing oil starvation and connecting rod, bearing, and bolt failure.

Analysis

The aircraft was at 2,000 feet over Fire Island beach when the engine failed. During a landing on a sandy beach, the gear sank into the sand and the aircraft nosed over. A sealant used on the oil pressure screen housing gasket was found in the main bearing oil supply holes. The number one connecting rod, bearing, and bolt failed. Metal was found in the oil, suction screen, and oil pressure screen housing. Textron Lycoming does not have a procedure for the use of a sealant on any gaskets during the assembly of engines. 100 hour and annual inspections were performed 1.7 hours prior to engine failure. Spectrometric oil analysis was normal and the oil screen was cleaned during the inspections.
