Required Actions
Perform a one-time visual inspection to measure clearances between the engine forward feed pipe and shroud sleeve within 500 flight hours after the effective date. If clearance ≤6 mm, conduct an operational test for fuel leaks prior to further flight. If leakage is found, replace the shroud sleeve with a new improved part. Repeat the operational test every 500 flight hours until paragraph (c) is completed.
