Unsafe Condition

Hydraulic fluid may enter the cabin due to insufficient clearance between the inboard leading edge slat power drive unit hydraulic pressure tube and the adjacent pneumatic duct, or due to chafing of the hydraulic tube or pneumatic duct.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Inspect the inboard leading edge slat power drive unit hydraulic pressure tube for clearance and chafing within 3,000 flight hours after the AD's effective date. If clearance is ≤0.25 inch or chafing is found, replace both hydraulic pressure and return tubes prior to further flight. Repair the pneumatic duct if chafing is found. Replace the hydraulic return tube within 4,000 flight hours for airplanes with previously replaced hydraulic pressure tubes. Use approved service bulletins and seek alternative compliance via FAA if needed.
