Unsafe Condition
Anti-rotation pin failures in the low pressure turbine (LPT) third stage vane could cause LPT case penetration.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Radiographically inspect LPT cases with Tinidur anti-rotation pins per PW Alert SB 5753, Rev 2. Remove engines with 16+ fractured/missing/bent pins within 10 cycles or before flight if 44+. Modify engines with 15+ pins per SB 5751, Rev 1. Report inspection results to FAA within 30 days.
