## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2024-10-13, which applies to all Airbus Helicopters Model AS332C, AS332C1, AS332L, AS 332L1, AS 332L2, and EC 225LP helicopters. AD 2024- 10-13 requires visually inspecting the bowls of the left-hand (LH) and right-hand (RH) fuel filters for any cracks and seepage. Depending on the inspection results, AD 2024-10-13 requires removing an affected fuel filter from service and replacing that part. AD 2024-10-13 also allows a certain fuel filter to be installed on any helicopter if certain actions are accomplished. Since the FAA issued AD 2024-10-13, additional inspection criteria was developed. This proposed AD would require the same actions as AD 2024-10-13 but would remove some helicopters from the applicability, add an inspection of the inner surface of the fuel filter bowls, and revise the tightening torque. The FAA is proposing this AD to address the unsafe condition on these products.
