What happened
Shortly after departing the airport, while climbing to the assigned altitude, the aircraft experienced a propeller overspeed. In response to the malfunction, the pilot attempted to return to the departure airport. During this maneuver, smoke began to fill the cockpit and the engine subsequently stopped functioning.
The pilot performed a forced landing in a wooded area. Following the impact, the aircraft was consumed by fire.
The investigation
Investigators identified an intense fire within the engine accessory section, specifically located near the turbocharger. Records indicated that the oil and oil filter had been replaced three days prior to the accident. The only flight operated by the aircraft since the oil service was a two-hour flight conducted on the morning of the accident. The investigation noted that the oil filter is positioned on the accessory case in close proximity to the turbocharger.
