Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of a tundra tire-equipped airplane related that after landing on a dry paved runway, he added engine power to expedite his taxi to the next taxiway intersection. As the airplane approached the intersection, the pilot applied heavy braking action while turning to the left, and the airplane nosed over. The pilot reported in his written statement to the NTSB that the airplane was equipped with double puck wheel brakes and 29-inch tundra tires, and he noted that excessive use of the brakes would cause the airplane to nose over. The airplane sustained substantial damage to the wings and vertical stabilizer. The pilot reported there were no preaccident mechanical problems with the airplane.
