ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2011-12-08 for Bell Helicopter Textron Inc. (Bell), Model 205A, 205A-1, 205B, 212, 412, 412CF, and 412EP helicopters. AD 2011-12-08 required a one-time inspection of the tail rotor (T/R) blade for corrosion and pitting. This new AD retains the requirements of AD 2011-12-08 while excluding certain T/R blades from the applicability. This AD was prompted by new manufacturing and inspection procedures implemented by Bell that correct the unsafe condition on more recently manufactured T/R blades. The actions of this AD are intended to address an unsafe condition on these products. DATES: This AD is effective July 16, 2020. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of July 5, 2011 (76 FR 35334, June 17, 2011).
