Flight Details
The flight was conducted as an intermediate stage-check for a student pilot, preparing for a multi-engine checkride. The preflight inspection and engine run-up were completed without any anomalies.
Sequence of Events
Approximately five seconds after the takeoff roll began, the left engine lost power. The airplane immediately veered to the left. The certified flight instructor (CFI), who was also on board, assumed control of the aircraft and closed both throttles. Despite this action, the airplane continued turning left and departed the runway surface.
Post-Accident Examination
After the airplane came to a stop, the left engine was found to be idling. The right main landing gear had collapsed, and the right engine had impacted the ground, causing it to stop. Following the accident, the left engine was test-run, and no mechanical malfunctions were identified.
The exact cause of the left engine power loss was not determined from the available information.
