The defining event best describes what happened. - [Takeoff: Landing gear collapse](https://openairdocs.org/ntsb-events/094) (defining event); cases with it: [Beech 58, 8 cases](https://openairdocs.org/ntsb-events/094/sequence.md?model=1152740), [All aircraft, 1,787 cases](https://openairdocs.org/ntsb-events/094/sequence.md) ## Analysis During the takeoff roll, the pilot accelerated the airplane to rotation speed. Upon starting to rotate the airplane, the nose landing gear began a retraction sequence, collapsing under the airplane, and the pilot reduced the throttles to idle and applied the brakes. The main landing gear also retracted, and the airplane slid to a stop on the runway, resulting in substantial damage to the lower fuselage. Both the pilot and the pilot rated passenger verified that the landing gear handle was in the down position prior to and after the accident sequence. Postaccident examination of the aircraft revealed damage to several wires leading to the landing gear selector switch on the instrument panel. The wires were found to be actively arcing when moved or touched. ## Aircraft - Registration: [N6037M](https://openairdocs.org/aircraft/N6037M), registered now, S/N TH-1022, built 1979 (OpenAirDocs) - Reported make and model: BEECH 58 (UNDESIGNATED SERIES) - Registry model: [Beech 58](https://openairdocs.org/model/beech-58) (registry code 1152740) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: TH-1022 - Year built: 1979 - Airframe hours: 4416.8 - Engines: Continental IO-520-CB 285 horsepower reciprocating; Continental IO-520-CB 285 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Raleigh Flying Club LLC - Registered owner: Raleigh Flying Club LLC - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, April 15, 2024, 35.6 hours before - Destination: AVL, Asheville, NC - Flight plan: IFR - Airport: RDU, Raleigh-Durham International Airport, runway 5R, 7,500 × 150 ft, asphalt - Equipment: ADS-B, Electronic flight bag or handheld device, Stall warning system ## Flight crew As NTSB recorded them.
