Unsafe Condition
Deterioration of the damping ring and associated retaining ring of the main landing gear (MLG) door actuator can increase friction inside the actuator, restricting the MLG door opening by gravity during the landing gear alternate (free-fall) extension system. This could prevent full extension and/or down-locking of the MLG, leading to MLG collapse during landing and potential damage to the airplane and injury to occupants.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the opening sequence of the MLG door for discrepancies, replace or modify certain MLG door actuators, and perform a flushing procedure when installing a new MLG door actuator. Also, revise the airplane flight manual (AFM) and conduct repetitive checks of specific Centralized Fault Display System (CFDS) messages.
