The NTSB's narrative final · quoted from the NTSB record
Witnesses observed the airplane flying low over houses. One witness stated that he heard the engine power decrease and that the airplane’s pitch attitude increased until the airplane stalled, descended in a spin, and impacted the ground. A postaccident examination of the wreckage and engine did not reveal any anomalies that would have precluded normal operation. The pilot had a history of pulmonary embolism; however, there are no indications that a medical condition contributed to the accident. The reason for the apparent loss of airspeed and the resultant stall could not be determined.
