Accident Sequence
The pilot was cruising at 2,000 feet when the oil pressure light first flickered, then came on steady. A few seconds later, the airplane began to vibrate. The pilot initiated an off-airport landing in a field. During the landing, the airplane struck a power line before impacting in an open field.
Engine Examination
Examination of the engine revealed that the engine oil drain plug was missing from the oil sump, and there was no oil in the engine. The engine had accumulated 72 hours since a factory overhaul.
Maintenance History
Twenty hours after the engine was installed in the airplane, an oil change was performed. The mechanic who performed the oil change reported that a quick drain was installed but stated he did not notice if it was safety wired and did not know who installed the quick drain. The airplane owner/mechanic who performed the engine installation declined to discuss the quick drain installation with the Safety Board investigator. Textron-Lycoming reported that they overhauled the engine and delivered it with two standard drain plugs and no quick drains installed.
