NTSB narrative
According to the pilot, the landing gear would not extend while attempting to land. The pilot elected to divert to another airport while he attempted to trouble-shoot the landing gear issue. The pilot was able to get the nose landing gear to extend but was unable to extend the main landing gear. The pilot performed a normal landing with the main landing gear up and the nose wheel extended. The airplane came to rest, canted to the left with the left wing resting in the snow, resulting in substantial damage. Examination of the airplane revealed that the hydraulic hose for the landing gear system had failed, resulting in the loss of hydraulic fluid. A review of the maintenance records revealed no evidence that the hose had ever been replaced. Cessna Aircraft Company issued Service Bulletin SEB92-8, with regard to the replacement of hydraulic landing gear hoses. In addition, the Cessna Model 210 and T210 service manual states that the hydraulic hoses should be replaced every 5 years. An examination of the remaining systems revealed no anomalies.
Probable cause
the failure of the mechanic to comply with the required replacement schedule resulting in the failure of the hydraulic line and the resulting gear up 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.
