Unsafe Condition

Fatigue cracks originating at the weld joining the drain boss to the combustion chamber outer case (CCOC), which could result in CCOC cracks and an uncontained engine failure.

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

Required Actions

Inspect drain bosses and Ps4 bosses of the CCOC for cracks using FMPI or FPI, and replace with serviceable parts if necessary. Inspect for proper Ps4 and drain boss material on specified CCOCs and replace if necessary. Replace CCOCs with welded-on bosses with improved, one-piece CCOCs. Installation of the one-piece CCOC terminates inspection requirements.
