Incident Overview
During a training flight, shortly after takeoff from runway 17, at approximately 1,000 feet above ground level, the left side of the engine cowling opened and began flapping. The certified flight instructor (CFI) assumed control of the aircraft and initiated a return to the airport on a downwind leg for runway 17.
Actions During Approach
As the CFI assessed the aircraft's position, she determined it was too low to reach the airport. She then turned off the fuel, mixture, and carburetor heat. The aircraft subsequently struck a utility pole with its left wing before touching down.
Post-Incident Statements
The CFI stated that, to the best of her recollection, neither she nor the student pilot touched the throttle during the sequence, though she noted that the throttle may have vibrated out of position slightly.
Maintenance and Preflight Details
Before the flight, a mechanic had loosened the left side of the engine cowling to check a landing light wire plug connection. After completing the check, the mechanic closed the cowling but did not fasten it. The student pilot performed a preflight inspection of the aircraft but did not discover the loose fasteners.
