Contributing to the accident was the intermittent warning horn which likely did not sound to warn the pilot about the misconfigured landing gear. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Use of equip/info: use of equip/system](https://openairdocs.org/ntsb-findings/02063015): Personnel issues › Task performance · Pilot (probable cause); cases with it: [Cessna 210N, 1 case](https://openairdocs.org/ntsb-findings/02063015/cases.md?model=2073453), [All aircraft, 1,391 cases](https://openairdocs.org/ntsb-findings/02063015/cases.md) - [Landing gear system: gear position and warning](https://openairdocs.org/ntsb-findings/01023260): Aircraft › Aircraft systems · Malfunction; cases with it: [Cessna 210N, 1 case](https://openairdocs.org/ntsb-findings/01023260/cases.md?model=2073453), [All aircraft, 37 cases](https://openairdocs.org/ntsb-findings/01023260/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Landing: Landing gear not configured](https://openairdocs.org/ntsb-events/095) (defining event); cases with it: [Cessna 210N, 4 cases](https://openairdocs.org/ntsb-events/095/sequence.md?model=2073453), [All aircraft, 584 cases](https://openairdocs.org/ntsb-events/095/sequence.md) ## Analysis The pilot reported that as the airplane approached the airport to land, he found that the runway he had planned to land on was closed, so he maneuvered to land on an open runway. He forgot to extend the landing gear and wheels up landed the airplane on its belly. The airplane skidded on its belly to a stop, which resulted in substantial damage to the primary structure of the underside of fuselage. The pilot reported no mechanical malfunctions or failures that contributed to the accident, but also reported that neither he nor the passenger heard the landing gear warning horn during the approach. During the functional testing of the landing gear system, the landing gear warning horn was found to be intermittent. ## Aircraft - Registration: [N9776Y](https://openairdocs.org/aircraft/N9776Y), registered now, S/N 21064595, built 1981 (OpenAirDocs) - Reported make and model: CESSNA 210 (N) - Registry model: [Cessna 210N](https://openairdocs.org/model/cessna-210n) (registry code 2073453) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 21064595 - Year built: 1981 - Airframe hours: 4584 - Engines: Continental IO-520-L13B 285 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Shinn William K - Airworthiness certificate: Standard, Normal - Last inspection: Annual, February 16, 2024, 30 hours before - Departed: EHR, Henderson, KY - Destination: Same as departure - Airport: MVN, Mount Vernon, runway 15, 3,146 × 100 ft, asphalt - Equipment: Auto-pilot, Angle of attack indicator, ADS-B, Stall warning system, Onboard weather, Electronic flight bag or handheld device ## Flight crew As NTSB recorded them.
