Superseding AD Proposed for R44 Flex Plates and Clutch Yokes

The FAA has proposed to supersede Airworthiness Directive (AD) 2024-19-11, which applies to all Robinson R44 and R44 II helicopters. NAAA previously reported on AD 2024-19-11 in March 2024. 

The proposed superseding AD will retain all requirements of the original AD and update the alternative action to repetitively inspect a yoke that has reached the specified threshold instead of replacing it. It also adds the option to use Bonderite stripper S-ST 5251 instead of Cee-Bee stripper A-292, since the later could be difficult for some operators to obtain. 

Comments are due March 17, 2025. You can find the proposed superseding AD here.
