           Background: The FAA received reports of fatigue cracks in the end cap of main landing gear hydraulic actuators manufactured by Frisby Aerospace and installed on the affected aircraft. The actions specified by this Directive are intended to prevent the main landing gear from failing to lock down due to the hydraulic actuator cracking and separating, which could result in loss of control of the aircraft during landing, taxi, or ground operations.
