On September 6, 1986, a Cessna P337 (registration N90BK) operated by Yingling Aircraft was involved in an aviation accident near Wichita, KS. Investigators recorded the probable cause as: A leaking hydraulic hose to the right main gear door actuator, deteriorated from age, depleted hydraulic fluid, preventing gear operation. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
After a touch-and-go landing, a hydraulic fluid leak prevented gear retraction/extension. The aircraft landed with nose and right main gear extended; left main gear was in trail position, causing damage.
Incident
Following a touch-and-go landing, the flight crew detected a problem with the landing gear. A check of the hydraulic system revealed a lack of fluid in the reservoir. The pilots were unable to either retract or extend the gear. Subsequently, they landed the aircraft with the nose and right main gear extended, while the left main gear remained in a trailing position.
Damage
During the landing, the left wing tip, left main gear door, and left stabilizer sustained damage.
Investigation
An examination of the hydraulic system determined that a hose connected to the right main gear door actuator was leaking. The leak had permitted the depletion of hydraulic fluid. The hose was found to be deteriorated due to age.
Probable cause
A leaking hydraulic hose to the right main gear door actuator, deteriorated from age, depleted hydraulic fluid, preventing gear operation.
