NTSB narrative
The airplane landed gear up. The pilot reported that he put the gear handle in the down position as he was crossing over the field to enter the downwind leg of the traffic pattern for runway 20. At this time he noticed that the green landing gear annunciator light had illuminated. Due to the high level of traffic in the pattern, the pilot did not look into the mirrors to visually check if the landing gear had deployed successfully like he usually does. During the landing flare, the airplane's tail impacted the runway causing the airplane to bounce. The tail came down and impacted the runway again. Shortly thereafter, the entire airplane spun off the runway to the left onto the grass separating the taxiway and the runway. A Federal Aviation Administration (FAA) inspector examined the airplane after the accident occurred. He stated that the main landing gear doors were closed, and the main gear was in the fully retracted position. The nose wheel had partially extended. The FAA inspector interviewed several witnesses who heard the airplane's engine increase in power just prior to the landing. According to the Cessna 210 Owners Manual, the landing gear and doors operate in a specific sequence. Once the pilot places the gear position handle out of the neutral position, the engine driven hydraulic pump begins to create hydraulic pressure and transfers it to the hydraulic actuators, which operate the landing gear doors and landing gear. When the gear position handle is placed in the down position, the hydraulic pump supplies pressure to the door's actuators first, allowing the doors to open. Then, the hydraulic pressure will switch to the landing gear actuators, and the gear will extend. Once the landing gear has completed the extension, the hydraulic pressure will switch back to the door's actuators, and the doors will close. When the doors have completely closed, the gear position handle will return to the neutral position, completing the process.
Probable cause
the pilot's failure to extend the landing gear prior to landing.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
