Event Description
The flight was initially aborted due to a magneto problem. After the defect was corrected, the pilot decided to fly to McAllen, Texas, for further repairs. During the subsequent takeoff roll, the aircrew noticed sparks and flares emerging from the left side of the cargo or cabin area, behind a bulkhead. The crew immediately aborted the takeoff and attempted to extinguish the fire but were unsuccessful. The crew then evacuated the aircraft, which was subsequently destroyed by the fire.

An investigation was conducted to determine the origin of the fire. Despite the examination, the source of the fire could not be identified.
Probable Cause
The official findings listed the occurrence as a fire during the phase of operation: takeoff - initial climb. Specific findings include: (c) fuselage - fire; (c) reason for occurrence undetermined; Fuselage, bulkhead - burned; Aborted takeoff - performed - pilot in command.
