✈️Proposed Airworthiness Directive for Airbus Helicopters EC 155B
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC 155B and EC155B1 helicopters. This proposed AD was prompted by a determination that the required forces to jettison the windows exceed the maximum jettisoning effort requirements and the development of a modification of the jettisonable windows. This proposed AD would require replacement of the jettisonable windows and seals on the sliding doors and fixed panels on the left-hand and right- hand sides. This proposed AD would also require the installation of new labels. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️New Airworthiness Directive for Safran Helicopter Engines
The FAA is adopting a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2B2 engines. This AD was prompted by a manufacturer review of collected data from in- service engines that indicated the preference injector may clog over time caused by fuel coking, which decreases the permeability of the preference injector. This AD requires initial and repetitive non- extinguishing tests for engine flameout and replacement of the preference injector if necessary, a one-time modification (software upgrade) of the electronic engine control unit (EECU) and, for certain engines, repetitive replacements of the preference injector. 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 all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2 and MBB-BK 117 D-3 helicopters. This proposed AD was prompted by reports of airspeed and altitude indication errors. This proposed AD would require revising the existing rotorcraft flight manual supplement (RFMS) for the helicopter and replacing the air conditioning system (ACS) condenser outlet grids with ACS condenser outlet covers, and would prohibit installing ACS condenser outlet grids. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More🚁FAA Issues Airworthiness Directive for Robinson Helicopter Inspections
The FAA is superseding Airworthiness Directive (AD) 2024-19-11 for all Robinson Helicopter Company Model R44 and R44 II helicopters. AD 2024-19-11 required visually inspecting a certain flex plate assembly (flex plate) and certain clutch shaft forward yokes (yokes), including each flex plate bolt, and depending on the results, taking corrective actions. AD 2024-19-11 also required removing certain yokes from service within a specified threshold, or as an alternative, performing in-depth inspections. Since the FAA issued AD 2024-19-11, it has been determined that clarifications regarding the alternative inspections are necessary. This AD requires the actions of AD 2024-19- 11 and clarifies that the alternative inspections are repetitive and adds a particular paint remover option to use when performing those alternative inspections. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More🛩️New Airworthiness Directive for Airbus Helicopters EC225LP
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model EC225LP helicopters. This AD was prompted by the identification of missing electrical bonding on a certain part-numbered additional and optional search light (search light). This AD requires installing an electrical bonding braid modification. 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 Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. This AD was prompted by a report of a sliding door that was locked in the open position detaching from the helicopter during flight. This AD requires modifying certain upper rail rollers, installing a label on each sliding door, and prohibits installing affected upper rail rollers or a door having an affected upper rail roller. 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 Safety Compliance
The FAA proposes to supersede Airworthiness Directive (AD) 2020-06-13, which applies to certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2020-06-13 requires determining the accumulated hours time-in-service (TIS) of certain part-numbered main gearbox (MGB) suspension bar rear attachment fittings (fittings) and bolts and establishes reduced life limits. Since the FAA issued AD 2020-06-13, it was determined that modifying the MGB suspension bar fittings link and installing improved MGB suspension bar fitting bolts are necessary. This proposed AD would require modifying the MGB suspension bar link, installing newly- designed bolts, and prohibit installing certain parts. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More🚁New FAA Airworthiness Directive for Leonardo S.p.A. Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.A. Model A119 and AW119 MKII helicopters. This 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 AD requires installing a battery discharge detector and revising the existing Rotorcraft Flight Manual (RFM) for the helicopter. 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🚁FAA Proposes Airworthiness Directive for Airbus Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC 130 B4 and EC 130 T2 helicopters. This proposed AD was prompted by a report of heavy damage on the fenestron due to the loss of the tail rotor (TR) blade, which broke at the TR hub tension-torsion bar (tension-torsion bar). This proposed AD would require inspecting the tension-torsion bar and, depending on the inspection results, taking corrective actions. This proposed AD would also prohibit performing maintenance using certain maintenance manuals. These proposed 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 Airworthiness Directive for Bell Textron Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited (BTCL) Model 505 helicopters. This AD was prompted by reports of possible chafing in certain locations between the basic and supplemental helicopter wiring and the structure. This AD requires repetitively inspecting the wire harnesses at certain locations for damage, and if any wire damage is found, repairing the damaged wire/bundles, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
