Forced landing following engine power loss

Casualties unknown • Redlands, CA, US

A pilot was forced to perform an emergency landing after experiencing a total loss of engine power during the cruise phase of flight.

What happened

The fuel tanks had been refueled prior to takeoff for the flight. Approximately 13 minutes into the cruise phase, the pilot experienced a total loss of engine power. The pilot reported that there was no vibration felt before the power loss occurred.

In an effort to restore engine power, the pilot performed several actions, including applying carburetor heat, adjusting the mixture setting, and repositioning the ignition key. None of these attempts were successful. Consequently, the pilot performed a forced landing approximately 1.5 miles north-northeast of the intended destination. During the landing rollout across rough terrain, the 1946 aircraft collided with a berm.

The investigation

A teardown inspection of the engine and its accessories was conducted following the accident. Investigators found no evidence of any preimpact malfunction. Specifically, both the carburetor finger screen and the gascolator fuel screen were observed to be clear. Additionally, the magnetos were found to be functional and the carburetor heat control was working properly.

Probable cause

The reason for the non-mechanical total loss of engine power could not be determined.
