Airworthiness Directives; Leonardo S.p.a. Helicopters Federal Aviation Administration FAA, DOT.
ACTION: Notice of proposed rulemaking NPRM.
AGENCY:

The FAA proposes to adopt a new airworthiness directive AD for certain Leonardo S.p.a. Model AW189
helicopters. This proposed AD was prompted by corrosion on the inlet check valve banjo fitting of emergency flotation system EFS float assemblies.
This proposed AD would require visually inspecting each banjo fitting installed on an affected EFS float assembly, and depending on the results, removing the banjo fitting from service.
This proposed AD would also require applying corrosion inhibiting compound to each banjo fitting installed on an affected EFS float assembly and prohibit installing an affected EFS float assembly unless the banjo fitting inspection, banjo fitting replacement, and corrosion inhibiting compound application requirements have been accomplished as specified in a European Aviation Safety Agency now European Union Aviation Safety Agency EASA AD, which is proposed for incorporation by reference IBR. The FAA is proposing this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by July 12, 2021.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:
