What happened
During the initial phase of flight, the aircraft experienced a critical loss of power immediately after beginning its takeoff roll. The incident occurred as the crew was attempting to depart, resulting in the aircraft departing from the runway and crashing.
Findings
Investigations into the accident revealed that the engine failed because a 4-way gas crane was left in the closed position. This mechanical state prevented proper fuel flow to the engine during the high-power demand of takeoff. The failure is attributed to the fact that the crew did not properly execute the pre-takeoff checklist, which would have identified the incorrectly positioned valve before the flight commenced.
