A factor was an excessive taxispeed. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Airport facilities/design: runway/landing area condition](https://openairdocs.org/ntsb-findings/03017035): Environmental issues › Operating environment · Not specified; cases with it: [Aeronca 15AC, 1 case](https://openairdocs.org/ntsb-findings/03017035/cases.md?model=0191202), [All aircraft, 61 cases](https://openairdocs.org/ntsb-findings/03017035/cases.md) - [Landing gear system: brake](https://openairdocs.org/ntsb-findings/01023242): Aircraft › Aircraft systems · Incorrect use/operation (probable cause); cases with it: [Aeronca 15AC, 3 cases](https://openairdocs.org/ntsb-findings/01023242/cases.md?model=0191202), [All aircraft, 297 cases](https://openairdocs.org/ntsb-findings/01023242/cases.md) - [Performance/control parameters: surface speed/braking](https://openairdocs.org/ntsb-findings/01062045): Aircraft › Aircraft oper/perf/capability · Not specified (probable cause); cases with it: [Aeronca 15AC, 1 case](https://openairdocs.org/ntsb-findings/01062045/cases.md?model=0191202), [All aircraft, 238 cases](https://openairdocs.org/ntsb-findings/01062045/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Landing-landing roll: Nose over/nose down](https://openairdocs.org/ntsb-events/096) (defining event); cases with it: [Aeronca 15AC, 2 cases](https://openairdocs.org/ntsb-events/096/sequence.md?model=0191202), [All aircraft, 2,287 cases](https://openairdocs.org/ntsb-events/096/sequence.md) ## 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. ## Factual narrative 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.
