ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2014-11-02 for Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters. AD 2014-11-02 required repetitively inspecting frame number (No.) 9 for a crack. This AD was prompted by Airbus Helicopters developing a modification that provides an optional terminating action for the repetitive inspections required by AD 2014-11-02. This AD retains the requirements of AD 2014-11-02, provides an optional terminating action for the repetitive inspections, and reduces the applicability by excluding certain post-modified helicopters. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective August 17, 2021.
