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.
Learn More✈️New FAA Airworthiness Directives Impact Boeing 777 Maintenance Costs
The FAA is superseding Airworthiness Directive (AD) 2012-07- 06, which applied to certain The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes. AD 2012-07-06 required revising the maintenance program to update inspection requirements to detect fatigue cracking of principal structural elements (PSEs). This AD was prompted by new revisions to the airworthiness limitations of the maintenance planning document and damage tolerance rating check form document. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️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.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model SA341G and SA342J helicopters. This AD was prompted by a report of a pilot collective pitch stick handle grip that broke when pulled. This AD requires replacing certain pilot collective pitch stick handle grips and prohibits installing those pilot collective pitch stick handle grips. 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.
Learn More✈️Proposed Airworthiness Directive for Bombardier Airplanes by FAA
The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. This proposed AD was prompted by reports that the flap system on-board recorder (FSOBR) interfaces with the flap control unit signals and may result in the flap control unit monitors tripping, causing Flap Fail messages and possibly an uncommanded flap movement. This proposed AD would require the disconnection of the FSOBR and prohibit future installation of this system. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️FAA Proposes Airworthiness Directive for Dassault FALCON 7X
The FAA proposes to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This proposed AD was prompted by hydraulic leakage from the spoiler power control unit (SPPCU) in service. Relevant investigations determined that, following certain failures, the spoiler electrical control unit (SPECU) can deliver an untimely and permanent activation command to the SPPCU standby electrical pump, which can possibly result in overheating and significant hydraulic leakage of the unit. This proposed AD would require replacement of affected SPECUs, and would prohibit the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️Proposed Airworthiness Directive for Airbus Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model SA341G and SA342J helicopters. This proposed AD was prompted by reports of disbonding of the stainless steel leading edge protection of certain part-numbered main rotor blades (MRB). This proposed AD would require repetitively tap inspecting the MRB and, depending on the results, repairing or replacing the MRB. This proposed AD would also prohibit installing those MRB 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 proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model SA330J helicopters. This AD was prompted by the determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance records by incorporating new or more restrictive airworthiness limitations, 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.
Learn More✈️Airworthiness Directive for BRP-Rotax Engines
The FAA is adopting a new airworthiness directive (AD) for certain BRP-Rotax GmbH & Co KG (Rotax) Model 912 iSc2 Sport, 912 iSc3 Sport, 915 iSc2 C24, and 915 iSc3 C24 engines. This AD was prompted by a report of deviations during the manufacturing process that caused incorrect application of a certain thread-locker to certain sprag clutch housing and oil spray nozzles. This AD requires repetitive operational checks of the battery backup function with removal of the engine from service if insufficient battery power is found, one-time inspections of the oil spray nozzle and generator stator assembly, and, depending on the results of the inspections, replacement with parts eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
