Unsafe Condition
Corrosion pitting and cracking of the chromed area of the piston rods for the main landing gear (MLG) retraction actuators, which could result in rupture of a piston rod, non-damped extension of the MLG, high loads on the fully extended MLG, and consequent reduced structural integrity of the MLG.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the chromed area of the left and right piston rods for the MLG retraction actuators for cracking. If cracking is found, replace the affected MLG retraction actuator with a new actuator. Perform repetitive ultrasonic inspections for corrosion pitting and cracking of the inner surface of the piston rods. If corrosion pitting or cracking is found, replace the affected MLG retraction actuator with a new actuator. Send inspection results to the manufacturer.

Compliance Time
Before further flight or within the next 10 landings, depending on the results of the ultrasonic inspection.
