✈️Proposed Airworthiness Directive for Bombardier Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-1A11 (600) and CL-600-2A12 (601) airplanes, and certain Model CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.

✈️FAA Proposes Airworthiness Directive for Boeing Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-700, 737-800, 737-900, 737- 900ER, 737-8, and 737-9 series airplanes. This proposed AD was prompted by a report of a passenger being unable to exit the lavatory during flight due to a broken latch that prevented toggling of the lock. This proposed AD would require replacing lavatory bifold door latches with latches having an improved design. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.

✈️FAA Proposes Airworthiness Directive Impacting Honda Aircraft

The FAA proposes to supersede Airworthiness Directive (AD) 2021-22-12, which applies to certain Honda Aircraft Company LLC (Honda) Model HA-420 airplanes. AD 2021-22-12 requires removing and cleaning the inner diameter of the flap control pushrods and repetitively applying corrosion inhibiting compound (CIC) to this area. Since the FAA issued AD 2021-22-12, new flap control pushrods have been approved that are more corrosion resistant and do not require repetitive CIC applications. This proposed AD would retain all actions of AD 2021-22- 12 and would require replacing the flap control pushrods with improved design pushrods for all airplanes affected by AD 2021-22-12, as well as for other airplanes not affected by AD 2021-22-12. The FAA is proposing this AD to address the unsafe condition on these products.

🚁Airbus Helicopters AD

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD results from a report of the loss of the tail rotor pitch control due to a fracture of the tail rotor slide of the tail rotor head (TRH) assembly. This AD requires inspecting the slide of the control plate of the TRH assembly for any score, scratch, crack, or corrosion, removing corrosion and replacing the TRH assembly, slide of the control plate, or pitch control assembly if discrepancies are found, and reporting the results of the inspection. This AD prohibits installing an affected TRH assembly unless the actions of this AD are accomplished. All of these actions are 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.

✈️Proposed Airworthiness Directives for Boeing 737 Aircraft Compliance

The FAA proposes to supersede Airworthiness Directive (AD) 2023-09-04, which applies to certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, and certain Model 737-8 and -9 airplanes. AD 2023-09-04 requires inspecting all escape slide assemblies to identify affected parts and replacing affected escape slide assemblies with different assemblies. Since the FAA issued AD 2023-09-04, it was determined that additional airplanes might be affected by the unsafe condition. This proposed AD would retain the requirements of AD 2023-09-04 and require those actions for additional airplanes, including Model 737-8200 airplanes. The FAA is proposing this AD to address the unsafe condition on these products.

🚁New FAA Airworthiness Directive for Bell Textron Helicopters

The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited (Bell) Model 505 helicopters. The FAA previously sent this AD as an emergency AD to all known U.S. owners and operators of these helicopters. This AD was prompted by deformation and/or improper pin engagement in the knuckles of the door hinge on the aft movable ballast box assembly. This AD requires removing all ballast weights from the aft movable ballast box assembly and prohibits the use of ballast weights within the aft movable ballast box assembly, as specified in a Transport Canada emergency AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

✈️New FAA Regulation on Thommen AC32 Digital Air Data Computers

The FAA is adopting a new airworthiness directive (AD) for certain THOMMEN AIRCRAFT EQUIPMENT AG (THOMMEN) AC32 Digital Air Data Computers. This AD results from occurrences of AC32 Digital Air Data Computers (ADCs) that stop functioning below certain temperatures. This AD requires replacing an affected AC32 Digital ADC with a serviceable part. The FAA is issuing this AD to address the unsafe condition on these products.

✈️Proposed Airworthiness Directive for Boeing 767 Inspection Requirements

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. This proposed AD was prompted by discovery of a crack at one of the forward lower fastener holes, outside of the underwing longeron (UWL) following replacement of a cracked UWL fitting. This proposed AD would require performing an open hole high frequency eddy current (HFEC) inspection for cracks of the fastener holes common to the UWL fitting, upper drag splice angle, and lower drag splice angle, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

🚁New FAA Airworthiness Directive for Airbus Helicopters Model H160-B

The FAA is superseding Airworthiness Directive (AD) 2024-26- 01, which applied to all Airbus Helicopters Model H160-B helicopters. AD 2024-26-01 required measuring the axial play of the rotating scissors spherical bearings, and depending on the results, accomplishing corrective action and reporting inspection results. Since the FAA issued AD 2024-26-01, Airbus Helicopters issued revised material to extend the applicability to all rotating scissors spherical bearing serial numbers, change the initial compliance time, establish repetitive inspections, and extend the reporting requirements. This AD was prompted by a determination that the initial compliance time and reporting requirement needed to be modified and repetitive inspections for certain axial play measurements added. This AD retains the actions required in AD 2024-26-01, revises the initial compliance time, extends the definition of an affected part to all serial numbered rotating scissors spherical bearings, extends the reporting requirements, and requires repetitive inspections. This AD also prohibits installing an affected rotating scissors spherical bearing unless certain requirements are met. These actions are 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.

✈️FAA Airworthiness Directive for Airbus A350

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by an updated stress analysis on the forward (FWD) cargo door and its attachment piano hinges that revealed a risk of cracking and crack propagation on piano hinges 2 and 3, originating from opening- closing fatigue cycles of the FWD cargo door. This AD requires an inspection of the affected parts, and 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.
