Unsafe Condition
Wing anti-ice (WAI) ducts may collapse, crack, or rupture, causing leakage of hot air in the under-floor pressurized area of the fuselage when the anti-ice system is turned on, resulting in insufficient heat for the anti-ice system and aerodynamic degradation.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Revise the Airplane Flight Manual (AFM) to include specific limitations regarding operations with wing anti-ice system faults and inoperative anti-ice bleed leak detection loops. Inspect the WAI ducts to detect damage, including open or cracked external shrouds, and replace any damaged duct with a new duct or a duct with the same part number. Replace all four WAI ducts with new ducts that have new part numbers.
