- [Landing-landing roll: Landing gear collapse](https://openairdocs.org/ntsb-events/094) (defining event); cases with it: [Beech A36, 12 cases](https://openairdocs.org/ntsb-events/094/sequence.md?model=1151604), [All aircraft, 1,787 cases](https://openairdocs.org/ntsb-events/094/sequence.md)

## Analysis

The pilot reported that he had landed uneventfully at the conclusion of a local flight. However, during the landing rollout the pilot stated that he mistakenly selected the landing gear handle instead of the flap handle. As a result, the nose landing gear collapsed, damaging the nose gear support fittings and nose gear assembly. The pilot noted that there were no failures or malfunctions associated with the airplane prior to the accident.
