2024-06-06: The FAA is superseding Airworthiness Directive (AD) 2021-25-03 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 7000-72 and Trent 7000-72C engines. AD 2021-25-03 required operators to revise the airworthiness limitation section (ALS) of their existing approved continuous airworthiness maintenance program by incorporating the revised tasks of the applicable time limits manual (TLM) for each affected engine model. Since the FAA issued AD 2021-25-03, the manufacturer again revised the TLM to introduce new or more restrictive tasks and limitations and associated thresholds and intervals for life- limited parts, which prompted this AD. This AD requires revising the ALS of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2008-11-13: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200, -200LR, -300, and -300ER series airplanes. This AD requires revising the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness by incorporating new limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This AD also requires the initial performance of certain repetitive inspections specified in the AWLs to phase in those inspections, and repair if necessary. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
2024-07-04: The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-524H-36 and RB211-524H-T-36 engines. This AD was prompted by reports of engine surges and a subsequent investigation which found that the surges may have been caused by material loss on the high-pressure compressor (HPC) stage 1 and stage 2 rotor path liners. This AD requires borescope inspections (BSIs) of the HPC stage 1 and stage 2 rotor path liners for material loss, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2008-11-14: We are adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-10-10F, DC-10-30F (KC-10A and KDC-10), DC- 10-40F, MD-10-10F, and MD-10-30F airplanes; and Model MD-11 and MD-11F airplanes. This AD requires installation of control cable freeze protection by making certain changes. This AD results from reports of standing water on the horizontal pressure panel above the main and center landing gear wheel wells. We are issuing this AD to prevent the accumulation of ice on the flight control cables in the wheel wells. When the landing gear doors open or vibration in this area occurs, such ice accumulation could break off and can cause injury to people or damage to property on the ground, can affect landing gear controls and rear spar flight control systems, can cause damage to other control systems, and might cause loss of control of the airplane.
2024-05-03: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes.

This AD requires repetitive inspections for cracking at the affected area, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
2024-05-02: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A320-214, A320-216, A320-251N, A320-271N, and A321-253NX airplanes. This AD was prompted by a quality review of the forward cargo door frame-to-fuselage skin panel assembly identified several fastener holes that deviated from the manufacturing requirements. This AD requires a geometrical check of the diameter of certain fastener holes for deviations, and if any deviation is found, repetitive special detailed inspections of the affected area for discrepancies and, depending on findings, accomplishment of applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2008-11-02: We are adopting a new airworthiness directive (AD) for all Lockheed Model L-1011 series airplanes. This AD requires revising the FAA-approved maintenance program by incorporating new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This AD also requires the accomplishment of certain fuel system modifications, the initial inspections of certain repetitive fuel system limitations to phase in those inspections, and repair if necessary. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
86-10-11 R1: 86-10-11 R1 AEROSTAR (RAVEN): Amendment 39-5350. Applies to Models S-40A, S- 50A, S-55A, S-60A, S-66A, S-77A, RX-6, RX-7 and W100LB (all serial numbers) Hot Air Balloons certificated in any category. Compliance: Required prior to further flight, unless already accomplished. To preclude propane fuel leakage which could result in an uncontained fire in the balloon basket, accomplish the following: (a) Visually check all of the fuel supply hose assemblies in the balloon to determine if any are identified by the part number code "FC321-06" followed by the date of manufacture code "3Q84" or "4Q84." (b) Prior to further use, remove all hose assemblies with markings as specified in paragraph (a) of this AD, or which contain "FC321-06" part number code but no date of manufacturer code and replace with assemblies of the same part number and a date of manufacture code other than "3Q84" or "4Q84." Make the appropriate entry in the aircraft maintenance records before returning the balloon to service.
