Aircraft involved
Probable cause & findings
The pilot’s unstabilized approach, which resulted in the airplane landing long and fast, and the pilot’s subsequent decision to steer the airplane off the side of the runway to avoid a runway overrun.
Factual narrative
According to the pilot who occupied the right front seat, during the flight the engine started to run rough. During landing, the airplane was fast and high, and touched down about 1,200ft past the approach end of the 2,890ft runway. A pilot rated passenger occupied the left front seat which was the only position configured with brakes. The pilot-rated passenger applied the brakes during the landing roll and the pilot maneuvered the airplane to exit the left side of the runway to avoid a runway overrun and impact with a fence. The airplane exited the left side of the runway and the right main landing gear collapsed, and subsequently skidded to a stop in the grass safety area. The airplane sustained substantial damage to the aft section of the fuselage. During an interview with the National Transportation Safety Board Investigator-in-charge, a flight instructor, who was seated in the rear of the airplane during the flight, reported that the airplane touched down about 100 knots, with between 40-60 percent of the runway remaining. According to the manufacturer's airplane operator manual, the minimum runway landing roll distance at sea level is 785ft when the ground speed is 70 knots. The METAR at the airport reported that about the time of the accident, the wind was from 07° at 12 knots and gusting to 17 knots. The airport field elevation was 789ft and the pilot landed to runway 34. According to the pilot who occupied the right front seat, during the flight, the engine started to run roughly.
