Piper PA-23-250 Aztec, G-BGTG


Failure of the right gear hydraulic actuator when the landing gear was selected down led to the loss of the hydraulic fluid in the system. The emergency lowering system was used, which deployed the left and nose landing gears, but the right gear remained retracted. A successful emergency landing was subsequently carried out. Examination of the actuator revealed the presence of pre-existing stress corrosion and critical cracking, in the actuator body. It was concluded that the failure was associated with the maritime environment in which the aircraft had operated, possibly exacerbated by very thin anodic coating.
