Incident Overview
While conducting a downwind departure, the pilot notified air traffic control of an emergency and requested permission to land immediately. Controllers responded by clearing the pilot to land on any runway of his choice. The pilot then initiated a turn to establish a close base leg to the same runway he had departed from. The turn did not stabilize and instead progressed into a descending spiral, which continued until the aircraft struck the ground.
Emergency and Maneuver
At the time of the emergency call, tower personnel observed smoke trailing from the aircraft. The exact source of the smoke was not immediately apparent. The pilot's maneuver, described as a close base entry, evolved into an uncontrolled spiral descent. No further details about the aircraft's altitude or speed during the descent were provided in the report.
Postaccident Findings
A detailed examination of the aircraft after the accident focused on the electrical system. Inspectors found that the electrical system had been improperly installed. Specifically, it lacked adequate circuit protection, such as fuses or circuit breakers, and did not employ wiring that met aviation standards. The use of non-aviation type wire was noted as a deviation from standard practices. The examination did not identify the installer or the timeline of the installation.
