On May 25, 2000, a Cessna T210M (registration N761VZ) was involved in an aviation accident near Boise, ID. Investigators recorded the probable cause as: Hydraulic hose deterioration resulting in total hydraulic fluid loss and rendering the gear system inoperable. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During landing, the right main landing gear of a Cessna T210M collapsed after the pilot was unable to fully extend it. Post-crash examination revealed a deteriorated hydraulic hose caused total fluid loss, rendering the gear system inoperable.
Incident Overview
As the pilot of a Cessna T210M approached the destination airport, the landing gear was lowered. The tower controller then advised that the gear did not appear to be locked down. A flyby was conducted, which confirmed that the right main landing gear had only partially extended. The pilot attempted corrective actions, but these were unsuccessful.
Landing and Gear Collapse
The pilot subsequently returned to the airport and performed a power-off landing with full flaps on runway 28L. During the landing roll, the right main landing gear collapsed. The collapse resulted in damage to the right horizontal stabilizer.
Post-Crash Examination
An examination conducted after the incident found that the hydraulic hose connecting the system to the nose gear door actuator had deteriorated. This deterioration allowed a complete loss of hydraulic fluid, which made the landing gear system inoperable.
Probable cause
Hydraulic hose deterioration resulting in total hydraulic fluid loss and rendering the gear system inoperable.
