After taking off from Fort Smith, a pilot experienced engine sputtering, made a precautionary landing, and performed a normal engine run-up. On a subsequent takeoff, the engine sputtered again, leading to a forced landing and nose-over. No cause for the power loss was found.

First Flight and Precautionary Landing

The pilot took off from Fort Smith and leveled the aircraft at 500 feet above ground level (AGL). While following a river to inspect some property approximately five miles away, the engine began to sputter and run irregularly. The pilot executed a successful precautionary landing in a field. After landing, a thorough engine run-up was performed, and all systems checked normal.

Second Flight and Forced Landing

Believing the engine may have passed water, the pilot decided to take off again and proceed to Hardin, Montana. About two minutes after takeoff, the engine began sputtering and running irregularly once more. The pilot attempted to restore power but could not achieve any improvement. A forced landing was made in a field beyond some power lines.

Post-Accident Examination

During the landing roll, the pilot applied heavy brakes to stop before reaching a ditch, causing the aircraft to nose over. An examination of the aircraft and engine was conducted, but no cause for the power loss was found.
