What happened
Following takeoff, the pilot noticed engine oil accumulating on the windshield, which significantly restricted forward visibility. The pilot decided to return to the airport for landing. Upon touchdown, the aircraft bounced, prompting the decision to execute a go-around. During the climbout phase, the aircraft struck trees on rising terrain and crashed.
The investigation
Post-accident examination revealed that the oil filler/inspection cap had been improperly secured during preflight checks. This mechanical oversight allowed engine oil to leak onto critical flight surfaces during operation.
Findings
The primary factors contributing to this accident included the improper securing of the oil filler cap, which led to an in-flight oil leak. The resulting obstruction of the pilot's forward vision compromised situational awareness and control during the critical go-around maneuver.
