During departure from Runway 27, the pilot experienced an engine power loss after retracting landing gear. Attempting to return, the aircraft impacted a field left wing first, coming to rest 20 feet beyond initial impact. Stall warning sounded throughout.

Incident Overview

The pilot reported that after departing from Runway 27, at approximately 400 feet above ground level and immediately following the retraction of the landing gear, the engine experienced a loss of power. In response, the pilot executed a 180-degree left turn to establish a downwind leg, intending to return to the runway. When it became apparent that engine power would not be regained, the pilot made another left turn in an effort to reach the runway for landing.

Impact and Post-Impact

The aircraft contacted a field left wing first and came to rest approximately 20 feet beyond the initial engine impact. The pilot stated that the stall warning was sounding during much of the attempted return to the runway. The surrounding area consisted of flat, plowed farm fields.

Inspection Findings

An inspection of the aircraft and engine systems revealed no defects, with the exception of the fuel injection unit, which was destroyed.
