🚁FAA Airworthiness Directive for Airbus Helicopters Safety Compliance

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.

🚁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.

🚁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.

🚁Proposed Airworthiness Directive for Airbus Helicopters AD 2025-0916

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.

🚁FAA Proposes New Airworthiness Directive for Airbus Helicopters

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.

🚁FAA Proposes Airworthiness Directive for Airbus Helicopters

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters. This proposed AD was prompted by reports of false engine fire warnings. This proposed AD would require replacing affected engine fire detectors and prohibit installing an affected engine fire detector or an engine that contains an affected engine fire detector, 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.

🚁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.

This AD was prompted by reports of malfunctioning emergency fuel shut-off switches on the warning unit. This AD requires inspecting certain switches on the warning units, and depending on the results, replacing or repairing the warning unit. This AD also allows installing certain warning units provided 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 Proposes New Airworthiness Directive for Leonardo Helicopters

The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.a. Model A119 and AW119 MKII helicopters. This proposed AD was prompted by a report of an electrical failure of the starter-generator, due to a rupture of the drive shaft, which resulted in a partial loss of battery power. This proposed AD would require installing a battery discharge detector and revising the existing Rotorcraft Flight Manual (RFM) for the 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.
