Background: Cases of nose landing gear up-lock problems have been reported on in-service aircraft. Investigation revealed corrosion initiated cracking of the actuator rod, which resulted in an internal hydraulic leak. In the case of a three-point landing, such cracking can lead to rod fracture and result in nose gear retraction.
