## Summary

We propose to supersede 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 requires a one- time inspection of the tail rotor (T/R) blade for corrosion and pitting. Since we issued AD 2011-12-08, Bell has implemented new manufacturing and inspection procedures that correct the unsafe condition on more recently manufactured T/R blades. This proposed AD would retain the requirements of AD 2011-12-08 while excluding certain T/R blades from the applicability. The actions of this proposed AD are intended to address an unsafe condition on these products.
