🚁FAA Issues Airworthiness Directive for Leonardo Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.A. Model A109E, A109S, and AW109SP helicopters. This AD was prompted by reports of incorrect installation of the motor (MTR) cables and the bonding braids connected to the engine fire extinguisher bottles. This AD requires inspecting the cables and bonding braids installation and, depending on the results, accomplishing corrective action, 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 superseding Airworthiness Directive (AD) 2021-09-14 which applied to certain Airbus Helicopters (Airbus) Model SA330J helicopters. AD 2021-09-14 required repetitively inspecting for a gap between the main gearbox (MGB) oil cooling fan assembly (fan) rotor blade and the upper section of the guide vane bearing housing, installing improved MGB fan rotor shaft bearings, and repetitively inspecting the improved MGB fan rotor shaft bearings. Since the FAA issued AD 2021-09-14, Airbus has developed modifications to the components of the MGB fan bearing assembly and issued new material regarding these modifications. This AD retains the actions required by AD 2021-09-14 and also requires installing the improved MGB fan rotor bearing assembly, which constitutes terminating action for the repetitive inspections. 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.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model SA341G and SA342J helicopters. This AD was prompted by reports of corrosion on the contact surfaces of the tail rotor inclined and horizontal drive shaft flanges. This AD requires repetitively inspecting the inclined and horizontal drive shaft flanges and, depending on the results, replacing the inclined or horizontal drive shaft. This AD also prohibits installing certain inclined and horizontal drive shafts unless certain requirements are met. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️FAA Proposes Airworthiness Directive for Airbus Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC635T2+, and EC135T3 helicopters. This proposed AD was prompted by reports of ruptured and deformed flexible couplings. This proposed AD would require inspecting the axial displacement of the tail rotor driveshaft and, depending on the results, taking corrective actions including inspecting the flexible couplings. This proposed AD would also prohibit installing a tail rotor drive shaft unless certain procedures are followed. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation 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 AS332L2 helicopters. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) or instructions for continued airworthiness (ICAs) and the existing approved maintenance or inspection program, as applicable, 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🚁Proposed Airworthiness Directive for Airbus Helicopters EC120 and EC130
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC120B, EC130B4, and EC130T2 helicopters. This proposed AD was prompted by a report of a missing retaining ring between the supply hose and the central supply coupling of an emergency floatation system (EFS) inflation assembly. This proposed AD would require inspecting for the presence of the retaining ring in an EFS with certain inflation assemblies installed and, depending on the results, taking corrective action. This proposed AD would also prohibit installing an EFS with those inflation assemblies installed. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More🚁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.
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 certain Airbus Helicopters Model AS332L1 and EC225LP helicopters. This AD was prompted by a determination of a possible interference of the hoist operator's helmet cord with the toggle switch of the hoist cable cut control. This AD requires replacing, or modifying and re- identifying, certain hoist shear toggle switch supports, and prohibits installing certain hoist shear toggle switch supports, 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 superseding Airworthiness Directive (AD) 2008-10-01 and AD 2010-05-51, which applied to certain Eurocopter France (now Airbus Helicopters) Model EC120B helicopters. AD 2008-10-01 required replacing certain part-numbered and serial-numbered spherical thrust bearings. AD 2010-05-51 required repetitively inspecting the main rotor (M/R) head rotor hub (rotor hub) and, depending on the results, taking corrective action. Since the FAA issued those ADs, the manufacturer revised the airworthiness limitations section (ALS) to incorporate various airworthiness limitations, tasks, and associated thresholds and intervals that were previously contained in service bulletins, as well as incorporate a new task. This AD requires revising the ALS of the existing maintenance manual (MM) or instructions for continued airworthiness (ICAs) and the existing approved maintenance or inspection program, as applicable, 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.
