An aircraft aborted takeoff, later departed but experienced engine issues, attempted to return, and crashed short of the runway after hitting a lamp pole and power line.

Incident Overview

The pilot initiated a takeoff on Runway 13R but aborted the procedure, taxied off the runway, and proceeded to the engine run-up area. Approximately two minutes later, the pilot announced readiness to depart and received takeoff clearance. During the initial climb after lift-off, the pilot stated the need to return for landing. Air traffic control cleared the pilot to land on any runway, and the pilot chose Runway 31L.

Witness Observations

Witnesses observed the aircraft in a sharp descending turn from an estimated altitude of 800 feet above ground level as it maneuvered back toward the runway. The descent rate increased, and the aircraft crashed approximately 1,000 feet short of the runway. During the impact sequence, the aircraft struck a lamp pole and a power line before coming to rest and catching fire.

Post-Impact Findings

Examination of the wreckage revealed that the fuel boost pump switches were found in the 'HIGH' boost position. The right propeller control was found in the feather position. The flight manual recommended the boost pumps be set to the 'LOW' position for takeoffs and landings. A test conducted on a similar aircraft using the high boost position resulted in a rough running engine and subsequent engine stoppage. Additionally, a witness to the accident reported hearing the engine sputtering and misfiring before the aircraft crashed.
