The defining event best describes what happened. - [Standing-engine(s) operating: AC/prop/rotor contact w person](https://openairdocs.org/ntsb-events/081) (defining event); cases with it: [Beech F33A, 1 case](https://openairdocs.org/ntsb-events/081/sequence.md?model=1151425), [All aircraft, 61 cases](https://openairdocs.org/ntsb-events/081/sequence.md) ## Analysis The pilot stated that after he started the airplane engine, he realized that the wheel chocks were still in place on the nose landing gear tire. He set the parking brake and exited the airplane with the engine still running. As the pilot removed the chocks, they inadvertently hit the propeller and pulled his arm into the propeller arc. The pilot sustained a serious injury to his right arm. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The airplane sustained minor damage to the propeller. ## Aircraft - Registration: [N2294L](https://openairdocs.org/aircraft/N2294L), registered now, S/N CE-676, built 1976 (OpenAirDocs) - Reported make and model: BEECH F33A - Registry model: [Beech F33A](https://openairdocs.org/model/beech-f33a) (registry code 1151425) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: CE-676 - Year built: 1976 - Airframe hours: 6435 - Engines: TCM IO-520BA 285 hp reciprocating - Damage: Minor damage - Flight: Personal, Part 91 - Registered owner: Jc Flying Services Inc - Airworthiness certificate: Standard, Normal - Departed: TQH, Tahlequah, OK - Airport: TQH, Tahlequah Muni - Equipment: Unknown ## Flight crew As NTSB recorded them.
