Aircraft involved
Probable cause & findings
Maintenance personnel’s failure to properly secure the oil filter adapter when replacing the oil filter adapter gasket which resulted in the filter becoming loose, resulting in the loss of engine oil, and the subsequent total loss of engine power.
Factual narrative
The pilot reported that while in cruise flight he briefly had smoke in the cockpit. The smoke dissipated and after being cleared to land, the engine quit suddenly, and the propeller stopped rotating. He alerted the tower and immediately retracted the landing gear and flaps and established best glide airspeed. When landing was assured, he lowered the landing gear, but the right main landing gear did not extend. The right wing struck a runway light and was substantially damaged. Post-accident examination by the mechanic who worked on the airplane a few days prior to the accident revealed that the safety wire he cut while performing a gasket replacement on the oil filter adapter had not been removed and replaced. It is likely that because the cut safety wire was not replaced and secured when the filter adapter gasket was replaced, the filter became loose during engine operation which allowed for engine oil to leak out resulting in the subsequent loss of engine power due to oil starvation.
