The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a Model AW169 helicopters. This proposed AD was prompted by reports of in-flight pilot collective stick oscillation. This proposed AD would require a one-time measurement of the friction of the pilot collective stick assembly to verify that it is within the allowable range and, depending on findings, making an adjustment to restore the acceptable level of friction, 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.
