What happened
During an approach to a 1,500-foot long rough gravel site, an Alaska State Trooper pilot was performing a landing in a tundra-tire equipped airplane. During the landing roll, the pilot applied the brakes and pushed the elevator control stick forward. This action was intended to dampen the effects of the rough terrain.
However, excessive forward pressure on the control stick caused the aircraft to roll onto its nose. The impact resulted in the propeller and spinner striking the ground before the aircraft eventually came to rest upside-down. The pilot was not injured during the event.
The investigation
The investigation examined the physical damage to the aircraft, which sustained substantial damage to the right wing and the vertical stabilizer. The pilot reported that there were no mechanical problems with the airplane prior to the accident.
