On November 10, 1995, a Cessna 210E (registration N2314F) was involved in an aviation accident near Newport News, VA. Investigators recorded the probable cause as: the failure of the engine-driven hydraulic pump drive shaft, the pilot's failure to properly engage the emergency landing gear handle. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A pilot performed a gear-up landing after the main landing gear failed to extend and emergency procedures were unsuccessful. Postaccident examination revealed a failed hydraulic pump shaft and an improperly extended emergency handle.
Incident
A pilot reported that after takeoff, she retracted the landing gear without issue and remained in the airport traffic pattern. When she moved the landing gear lever to the down position, the nose gear extended, but the main landing gear did not. She exited the traffic pattern and attempted to extend the main gear using emergency procedures and the manual emergency hand pump, but these efforts were unsuccessful. She subsequently performed a gear-up landing on a grass strip adjacent to runway 20.
Postaccident Examination
Examination of the aircraft after the landing included a functional test of the landing gear using an external hydraulic pressure source, which showed the gear operated satisfactorily. Further inspection revealed that the engine-driven hydraulic pump shaft had failed. Additionally, the emergency landing gear handle was not completely extended, which prevented it from operating through its full stroke.
