- [Landing-landing roll: Nose over/nose down](https://openairdocs.org/ntsb-events/096) (defining event); cases with it: [Cessna 140, 49 cases](https://openairdocs.org/ntsb-events/096/sequence.md?model=2071602), [All aircraft, 2,287 cases](https://openairdocs.org/ntsb-events/096/sequence.md)

## Analysis

During the landing rollout, the pilot applied the brakes and the airplane nosed over. The fuselage, vertical stabilizer, and left wing struts were substantially damaged. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. He said that the accident could have been prevented if he had allowed the airplane to roll out without applying the brakes.

## Factual narrative

During the landing rollout, the pilot applied brakes and the airplane nosed over coming to rest in an inverted position on the runway. The fuselage, vertical stabilizer, and left wing struts were substantially damaged. Per a photograph provided to the investigator-in charge (IIC), the airplane was not equipped with the manufacture’s optional landing gear extensions, which extend the main wheels forward. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
