Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Formerly Held by Rolls-Royce plc) Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG RB211-524G2-19, RB211- 524G2-T-19, RB211-524G3-19, RB211-524G3-T-19, RB211-524H2-19, RB211- 524H2-T-19, RB211-524H-36 and RB211-524H-T-36 model turbofan engines. This AD requires replacement of the low-pressure turbine (LPT) stage 1 disk before it reaches its new Declared Safe Cycle Limit (DSCL) or within 25 flight cycles after the effective date of this AD, whichever occurs later. This AD was prompted by a determination by the manufacturer that the affected LPT stage 1 disks cannot operate until their former published life limit. The FAA is issuing this AD to address the unsafe condition on these products.
Establishment of Class E Airspace, Sleetmute, AK
This action establishes Class E airspace extending upward from 700 feet above the surface at Sleetmute Airport, Sleetmute, AK, to accommodate new area navigation (RNAV) procedures. This action ensures the safety and management of instrument flight rules (IFR) operations within the National Airspace System.
Airworthiness Directives; Airbus Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This proposed AD was prompted by reports of corrosion on attachment screws and fittings fastening the main gearbox (MGB) suspension bars to the fuselage. This proposed AD would require inspecting the affected parts and associated frame bores for discrepancies, and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all General Electric Company (GE) GEnx-1B64, -1B64/P1, -1B64/P2, - 1B67, -1B67/P1, -1B67/P2, -1B70, -1B70/75/P1, -1B70/75/P2, -1B70/P1, - 1B70/P2, -1B70C/P1, -1B70C/P2, -1B74/75/P1, -1B74/75/P2, -1B76/P2, and -1B76A/P2 model turbofan engines. This proposed AD was prompted by a report of a crack in the outer fuel manifold causing fuel leakage. This proposed AD would require initial and repetitive visual inspections of the cushioned loop clamp (``p-clamp'') and, depending on the results of the inspection, a spot fluorescent penetrant inspection (FPI) of the outer fuel manifold. Depending on the results of the FPI, this proposed AD would require replacement of the outer fuel manifold. This proposed AD would also require initial and repetitive replacements of the p- clamp. The FAA is proposing this AD to address the unsafe condition on these products.
