Incident Overview
A flight intended to check the performance of a newly installed or overhauled engine ended in an emergency landing after the engine lost power during initial climb. According to reports, the engine was run for approximately one hour before takeoff without any issues.
Flight Details
Both the pilot and a mechanic-passenger reported that during the initial climb after takeoff, the fuel pressure dropped and the engine subsequently lost power. The pilot did not change the position of the fuel selector after the power loss. The aircraft then made an emergency landing in a field, resulting in damage.
Post-Accident Examination
A post-accident examination and operational check of the engine revealed no fuel contamination or mechanical malfunction. During the check, the fuel selector was moved to the OFF position while the engine was running, and engine power was lost approximately 15 seconds later.
