ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2017-17-01, which applied to certain Airbus Helicopters Model AS332L2 and EC225LP helicopters. AD 2017-17-01 required repetitive inspections of the main rotor blade (MRB) attachment pins. This AD continues to require the repetitive inspections of the MRB attachment pins, and also requires repetitive measurement of the attachment pin chamfer at certain intervals after corrosion removal, as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which is incorporated by reference. This AD was prompted by the FAA's determination that it is necessary to measure the attachment pin chamfer after corrosion removal, that replacement of an attachment pin after four corrosion removals is no longer necessary, and that all Airbus Helicopters Model AS332L2 and EC225LP helicopters are affected by the unsafe condition. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective August 17, 2021. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of August 17, 2021.
