The defining event best describes what happened. - [Landing-flare/touchdown: Landing gear not configured](https://openairdocs.org/ntsb-events/095) (defining event); cases with it: [Burt Donald R LANCAIR 235, 1 case](https://openairdocs.org/ntsb-events/095/sequence.md?model=05624C9), [All aircraft, 584 cases](https://openairdocs.org/ntsb-events/095/sequence.md) ## Analysis The pilot reported that he selected the landing gear down before landing, however, the landing gear did not extend. The pilot determined that it was too late to safely execute a go-around, and the airplane subsequently landed on its belly, resulting in substantial damage to the lower fuselage. The pilot reported that there were no pre-accident mechanical failures or malfunctions with the airplane that would have precluded normal operation. Postaccident examination revealed that a toggle switch that is used to energize the hydraulic system for the extension of the landing gear was inadvertently left in the OFF position by the pilot. ## Aircraft - Registration: [N25DB](https://openairdocs.org/aircraft/N25DB), registered now, S/N 83, built 1993 (OpenAirDocs) - Reported make and model: LANCAIR 235 - Registry model: [Burt Donald R LANCAIR 235](https://openairdocs.org/model/burt-donald-r-lancair-235) (registry code 05624C9) (OpenAirDocs) - Registry engine: [Lycoming 0-235 series](https://openairdocs.org/engine/lycoming-0-235-series) (registry code 41505, 4 cycle) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 83 - Year built: 1993 - Airframe hours: 666.3 - Engines: Lycoming O-235 reciprocating - Damage: Substantial damage - Flight: Flight test, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, June 4, 2025 - Departed: IDP, Independence, KS - Destination: IDP, Independence, KS - Airport: H76, Pawhuska Muni, runway 17/35, 3,200 × 60 ft, asphalt - Equipment: Electronic multifunction display ## Flight crew As NTSB recorded them.
