What happened
While the aircraft was operating at cruise altitude, the engine experienced a sudden and complete loss of oil pressure. This mechanical failure occurred without prior warning, leading directly to the seizure of the engine shortly thereafter. With power no longer available, the pilot was forced to execute an emergency landing in a remote area characterized by dense tree cover. The aircraft impacted the trees and came to rest in an inverted position.
The investigation
Following the accident, investigators attempted to examine the engine to determine the root cause of the oil pressure failure. However, due to the severe damage sustained during the impact and the inverted position of the aircraft, a thorough examination of the engine components was not possible. Consequently, the specific mechanical reason for the loss of oil pressure could not be identified.
Findings
The primary finding is that the cause of the loss of oil pressure was not determined. The sequence of events began with the failure of the lubrication system, which led to engine seizure and the subsequent forced landing. The remote location and terrain contributed to the total loss of the aircraft.
