Airworthiness Directives; The Boeing Company Airplanes
The FAA is superseding Airworthiness Directive (AD) 2015-12- 03, which applied to certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. AD 2015-12-03 required repetitive freeplay inspections and lubrication of the right and left elevators, rudder, and rudder tab, and related investigative and corrective actions if necessary. This AD was prompted by engineering testing which revealed that the force being applied to the elevator to detect excessive freeplay was insufficient. This AD continues to require certain actions in AD 2015-12-03 for certain airplanes, and requires revising the existing maintenance or inspection program, as applicable, for certain other airplanes, to incorporate a revised or new elevator freeplay maintenance procedure, as applicable. This AD also adds airplanes to the applicability. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) (Type Certificates Previously Held by Messerschmitt-Bolkow-Blohm [MBB], and Eurocopter Deutschland GmbH [ECD]) Helicopters
The FAA proposes to supersede airworthiness directive (AD) 77- 04-06, which applies to Messerschmitt-Bolkow-Blohm (MBB) (now Airbus Helicopters Deutschland GmbH (AHD)) Model BO-105A and BO-105 C helicopters; AD 2002-13-06, which applies to certain Eurocopter Deutschland GmbH (ECD) (now Airbus Helicopters Deutschland GmbH (AHD)) Model BO-105A, BO-105C, BO-105 C-2, BO-105 CB-2, BO-105 CB-4, BO-105 CS-2, BO-105 CBS-2, BO-105S, and BO-105LS A-1 helicopters; AD 2016-25- 14, which applies to certain Airbus Helicopters Deutschland GmbH (AHD) Model BO-105LS A-3 helicopters; and AD 2021-10-14, which applies to certain Airbus Helicopters Deutschland GmbH (AHD) Model BO-105A, BO- 105C, BO-105S, and BO-105LS A-3 helicopters. AD 77-04-06 requires reducing the life limit on certain main rotor gearbox (MGB) supports. AD 2002-13-06 requires determining the calendar age, number of flights, and flight hours time-in-service (TIS) on certain tension-torsion (TT) straps; revising the Airworthiness Limitations Schedule (ALS) of the existing maintenance manual; removing and replacing each TT strap that has exceeded its life limit, or if the TT strap's total hours TIS or number of flights and age are not known; and modifying certain parts. AD 2016-25-14 requires establishing a life limit for certain TT straps and removing certain parts that have exceeded the new life limit. AD 2021-10-14 requires replacement of certain TT straps with serviceable parts, and implementation of a new storage life limit for certain TT straps. Since the FAA issued those ADs, new and more restrictive airworthiness limitations have been issued. This proposed AD would require incorporating into existing maintenance records requirements (airworthiness limitations) as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). This proposed AD would also prohibit the installation of certain part-numbered TT straps. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B model turbofan engines. This AD was prompted by several reports of fuel leaks caused by high cycle fatigue (HCF) cracks found at the braze joints on fuel manifolds, and the subsequent manufacturer redesign of the high-pressure turbine (HPT) fuel hose variable stator vane (VSV) manifold, VSV fuel hose manifold, low-pressure turbine (LPT) fuel hose variable bleed valve (VBV) manifold, and VBV fuel hose manifold. This AD requires removal and replacement of the fuel hydraulic lines. The FAA is issuing this AD to address the unsafe condition on these products.
Agency Information Collection Activities: Requests for Comments; Clearance of Renewed Approval of Information Collection: Advisory Circular: Reporting of Laser Illumination of Aircraft
In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval renew information collection. Advisory Circular 70-2A provides guidance to civilian air crews on the reporting of laser illumination incidents and recommended mitigation actions to be taken in order to ensure continued safe and orderly flight operations.
