Airworthiness Directives; The Boeing Company Airplanes
The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to all The Boeing Company Model 747-400, 747-400F, 747-8F, and 747-8 series airplanes. The NPRM was prompted by reports of dual flight management computer (FMC) cold starts during a critical flight phase such as takeoff and approach. The NPRM would have required an inspection to determine if certain software is installed, installation of FMC operational program software (OPS) and a software configuration check, and applicable concurrent requirements. Since issuance of the NPRM, the FAA determined that the installation of new software, as proposed in the NPRM, does not resolve the unsafe condition identified in the NPRM. Accordingly, the NPRM is withdrawn.
Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA is adopting a new airworthiness directive (AD) for Leonardo S.p.a. (Leonardo) Model A109E, A109S, A119, AW109SP, and AW119MKII helicopters. This AD requires removing certain main rotor (M/ R) floating ring assemblies from service. This AD also prohibits replacing any washer on any M/R floating ring assembly. This AD was prompted by a report of a washer debonding from the M/R floating ring assembly. The actions of this AD are intended to address an unsafe condition on these products.
