The NTSB's narrative final · quoted from the NTSB record

During the airplane's first flight after an annual inspection, the commercial pilot practiced touch-and-go landings and then flew the airplane for about 1.5 hours before returning to the airport. While on final approach to land, he reduced the engine power. The pilot stated that after the airplane touched down on the runway, it was traveling too fast to stop before the end of the runway but not fast enough to abort the landing. Subsequently, the airplane continued off the end of the runway, down an embankment, and came to rest inverted about 150 ft from the departure end of the runway. Postaccident examination of the brakes revealed no anomalies, and the pilot reported that there were no mechanical malfunctions or failures of the airplane that would have precluded normal operation. The pilot stated that he lands farther down the runway during full-stop landings because his hangar is at the far end of the runway. Thus, it is likely that the pilot landed the airplane too far down the runway and that it was traveling too fast to prevent a runway overrun.
