Unsafe Condition
Stress corrosion failure of the main landing gear (MLG) attach fittings could cause severe structural damage to the airplane during takeoff or landing.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Perform a visual inspection of the MLG attach fittings for cracks at intervals not exceeding 24 calendar months (initial within 12 months after effective date). If cracks are found in areas 1 or 3, replace the fitting with specified part numbers before further flight. If cracks are in area 2 within limits, apply LPS-3 oil and inspect every 7 days; if cracks exceed limits, replace the fitting before further flight. Replacement of both fittings terminates inspection requirements.
