Incident Overview
A pilot of a turbocharged airplane attempted to depart from a 1,900-foot-long grass and turf backcountry airstrip. The runway surface was rough, with occasional holes, soft spots, and areas of vegetation. The pilot calculated the density altitude at 5,495 feet. Although he had determined that the airplane should be able to complete the takeoff, during the latter part of the takeoff roll he became uncomfortable with the airplane's rate of acceleration and decided to abort the takeoff.
Runway Excursion and Damage
After making the decision to abort, the pilot was unable to stop the airplane before it departed the end of the runway. The airplane then rolled down a bank and nosed over onto its back. The accident sequence resulted in substantial damage to both wings and the fuselage.
Pilot Report
The pilot reported no indications of any engine or flight control anomalies during the event. In the Operator Safety Recommendation section of the NTSB form 6120.1, the pilot stated, "A decision to abort earlier may have prevented the roll off the end of the runway."
