## Probable cause

The pilot's excessive brake application during the landing roll, which resulted in a nose over.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

- [Action: incorrect action performance](https://openairdocs.org/ntsb-findings/02041015): Personnel issues › Action/decision · Pilot (probable cause); cases with it: [Maule MX-7-235, 3 cases](https://openairdocs.org/ntsb-findings/02041015/cases.md?model=5470207), [All aircraft, 1,386 cases](https://openairdocs.org/ntsb-findings/02041015/cases.md)

- [Landing-landing roll: Nose over/nose down](https://openairdocs.org/ntsb-events/096) (defining event); cases with it: [Maule MX-7-235, 3 cases](https://openairdocs.org/ntsb-events/096/sequence.md?model=5470207), [All aircraft, 2,287 cases](https://openairdocs.org/ntsb-events/096/sequence.md)

## Analysis

The pilot reported that he had made three touch and go landings on the dry lake. On the fourth landing he applied too much brake pressure, which resulted in a propeller strike and the airplane nosing over on its back. The airplane sustained substantial damage to the rudder, vertical stabilizer, and left wing tip.
