The NTSB's narrative final · quoted from the NTSB record
The pilot was returning to the airport after releasing some skydivers. He was following a training airplane in the traffic pattern and was gaining on it, so he decided to extend his downwind leg. On final approach to runway 08, his airplane was still gaining on the other airplane. The pilot reduced power and raised the nose to reduce airspeed to 85 mph. The airplane was "low and slow" as he passed over a lake, so he added power but not soon enough. The airplane touched down on the sandy shore of the lake short of the runway. The nose gear was torn off and the airplane nosed over.
