What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot reported that the aircraft had a dead battery and he had "hand propped" the aircraft. He stated that he primed the engine but failed to return the throttle to the idle position. When he "hand propped" the aircraft, it started, jumped the chock, and accelerated into a nearby pond. The pilot reported that he attempted to board and take control of the aircraft when it was moving, but slipped and fell. He could only manage to hang onto the left main landing gear for just a short time before having to left go. The aircraft was submerged in the pond.
