AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Remove and discard the loop clamps that hold the fuel manifold to the compressor rear frame (CRF) damper brackets. Inspect the fuel manifold for wear at each clamp location. Replace the clamps with new, zero-time parts. Revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) and air carrier's Continuous Airworthiness Maintenance Programs (CAMP) to require repetitive fuel manifold inspection and loop clamp replacement.
