✈️Proposed Airworthiness Directive for Airbus Helicopters Safety Compliance
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 C-2, MBB- BK 117 D-2, and MBB-BK 117 D-3 helicopters. This proposed AD was prompted by reports of damaged hoist hooks and hoist hook nuts. This proposed AD would require performing an inspection of the affected hoist hook and affected hook nut and, depending on the results of the inspection, replacing the affected hoist hook and affected hook nut. This proposed AD would also prohibit installing an affected assembly (hoist hook attached to the hook damper) unless it is installed using updated procedures. 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 Leonardo S.p.A. Model A109A, A109A II, A109C, A109K2, and A119 helicopters and certain AW119 MKII helicopters. This AD was prompted by a report of incorrect installation of the bolts that attach the pitch (longitudinal) actuator assembly and the roll (lateral) actuator assembly to their respective bellcrank assemblies of the cyclic control system. This AD requires inspecting the bolts for proper installation and, depending on the results, performing corrective actions. 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 Siam Hiller Holdings, Inc. (Siam Hiller), Model UH-12E (Army OH-23G and H-23F) and UH-12E-L helicopters. This AD was prompted by reports of cracks found in a main rotor (M/R) transmission drive shaft (drive shaft). This AD requires inspecting certain M/R drive shafts for a crack, prohibits installing certain M/R drive shafts unless the inspection is done, and prohibits using certain paint strippers. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited (Bell) Model 427 helicopters. This proposed AD was prompted by a report of a cracked transmission oil check valve (check valve). This proposed AD would require inspecting and measuring certain check valves and, depending on the results, repetitively inspecting and removing the check valve from service if it has leaks or is cracked. This proposed AD would also prohibit installing the affected check valves on any helicopter. 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 Deutschland GmbH (AHD) Model MBB-BK 117 D-3 helicopters. This AD was prompted by a report of over-torqued swashplate bolts on helicopters in service and in production. This AD requires removal of certain swashplate bolts from service and replacement with new (never previously installed on a helicopter) bolts, a one-time inspection for damage on the threads of the bearing ring and control ring of the swashplate and, depending on the results of the inspection, corrective actions. This AD also prohibits the installation of certain swashplates on any helicopter unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More🚁New Airworthiness Directives for Airbus Helicopters AS332C
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332C helicopters. This AD was prompted by a determination that new and 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. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More🚁Proposed Airworthiness Directive on Airbus Helicopters Inspections
The FAA proposes to supersede Airworthiness Directive (AD) 2021-26-07, which applies to all Airbus Helicopters Model EC120B helicopters. AD 2021-26-07 requires performing repetitive inspections of the tail rotor (TR) hub body and, depending on the inspection results, replacing certain parts, and accomplishing further inspections. AD 2021-26-07 also requires for certain helicopters removing from service any bolt, washer, and nut installed on the TR hub body at certain life limits and replacing them with airworthy parts and accomplishing further inspections. Additionally, AD 2021-26-07 prohibits the installation of a certain part-numbered TR hub body unless certain requirements are met. Since the FAA issued AD 2021-26- 07, it was determined that modifying the link of the TR hub body and splined flange by adding red paint marks is necessary to enable the detection of any loss of tightening torque. This proposed AD would require the same repetitive inspections and corrective actions as AD 2021-26-07 and would require modification of the link of the TR hub body, which would be a terminating action for the repetitive inspections. The proposed AD would also require repetitive inspections of the red paint line added during the modification of the link of the TR hub body for alignment. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2024-10-13, which applies to all Airbus Helicopters Model AS332C, AS332C1, AS332L, AS 332L1, AS 332L2, and EC 225LP helicopters. AD 2024- 10-13 requires visually inspecting the bowls of the left-hand (LH) and right-hand (RH) fuel filters for any cracks and seepage. Depending on the inspection results, AD 2024-10-13 requires removing an affected fuel filter from service and replacing that part. AD 2024-10-13 also allows a certain fuel filter to be installed on any helicopter if certain actions are accomplished. Since the FAA issued AD 2024-10-13, additional inspection criteria was developed. This proposed AD would require the same actions as AD 2024-10-13 but would remove some helicopters from the applicability, add an inspection of the inner surface of the fuel filter bowls, and revise the tightening torque. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 D-3 helicopters. This proposed AD was prompted by reports of momentary direct current (DC) power interruption in flight of both essential busses. This proposed AD would require revising the existing rotorcraft flight manual (RFM) for your helicopter, as 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.
