What happened
The Piper Cherokee PA-28-140 suffered a sudden loss of engine power during flight. The incident occurred approximately 15 minutes after the aircraft departed from the airport. Following the power failure, the pilot was forced to execute an emergency landing off the airport premises.
During the flight, the pilot reported that an oil line had broken, resulting in the complete loss of all engine oil. This mechanical failure directly led to the inability to maintain engine operation and necessitated the off-airport landing.
The investigation
Post-incident inspection was conducted by a mechanic who examined the aircraft for signs of the reported failure. The mechanic inspected both the engine compartment and the bottom of the fuselage for evidence of an oil leak or a broken oil line.
Despite the pilot's report, the inspection revealed no indication of an oil leak or a broken oil line in either the engine compartment or along the bottom of the fuselage. Consequently, the investigation could not identify the specific mechanical reason for the loss of engine oil.
