Unsafe Condition
Corrosion of the main landing gear (MLG) retraction actuator components was found in-service, either at the interface of the rod end and the piston or at the bracket and its related pins. This can cause the MLG retraction actuator to disconnect, leading to an MLG extension without damping, and a potential for MLG structural damage and possible collapse during landing.
Required Actions
Inspect the MLG retraction actuator components for corrosion; rectify any corrosion found; and, for certain MLG retraction actuators, install a new retraction actuator jam nut.
Compliance Time
Within 16 work-hours
