He immediately recognized his error and moved the handle back to the "down" position. Subsequently, he saw the left wing settle slightly, so he added power and performed a go-around. Once airborne, he asked the tower controllers to observe the landing gear, and they confirmed that the left main landing gear was "canted inward" and did not appear to be down and locked. The pilot stated that, during the second landing, he placed the gear handle in the “down” position and saw the gear indicator lights were showing "down and locked." However, during the landing roll, the left wing settled onto the runway. The airplane sustained substantial damage to the left aileron. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Factual narrative The pilot of the retractable landing gear-equipped airplane reported that, during the landing roll, he inadvertently moved the landing gear position lever to the "up" position. He immediately moved the lever back to the "down" position, but observed the left wing settle slightly, so he added power and performed a go around. Once airborne, he asked the tower controllers to observe the landing gear and they confirmed that the left main landing gear was "canted inward" and did not appear to be in a down and locked position. During the second landing he placed the gear handle in the down position and observed the gear indicators as "down and locked." During the landing roll, the left wing settled onto the runway. The airplane sustained substantial damage to the left aileron. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N5YB](https://openairdocs.org/aircraft/N5YB), registered now, S/N TC-952 (OpenAirDocs) - Reported make and model: Beech 55 (95B55) - Registry model: [Beech 95-B55](https://openairdocs.org/model/beech-95-b55) (registry code 1152705) (OpenAirDocs) - Category: Airplane - Serial number: TC-952 - Year built: 1966 - Airframe hours: 5000 - Engines: Continental IO-520-E 300 horsepower reciprocating; Continental IO-520-E 300 horsepower reciprocating - Damage: Substantial damage - Flight: Business, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, October 15, 2018 - Departed: TMB, Miami, FL - Destination: GNV, Gainesville, FL - Flight plan: IFR - Airport: GNV, Gainesville Rgnl, runway 07, 4,158 × 100 ft, asphalt - Equipment: Stall warning system, Onboard weather, Auto-pilot ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
