## Summary

We propose to supersede airworthiness directive (AD) 2017-07- 02 for Sikorsky Aircraft Corporation (Sikorsky) Model 269D and Model 269D Configuration A helicopters. AD 2017-07-02 currently requires reducing the life limit of and inspecting certain drive shafts. This proposed AD would retain the requirements of AD 2017-07-02 and propose repeating the inspections. The actions of this proposed AD are intended to detect and prevent an unsafe condition on these products.
