This AD also reduces the HPV clip replacement intervals, requires an additional revision of the existing AFM for certain airplanes, and limits the installation of HPV clips, 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.

ATR-GIE Avions de Transport Régional Airplanes
The FAA is adopting a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and Model ATR72 airplanes. This AD was prompted by the insufficient accuracy of a certain Angle of Attack (AoA) probe at low airspeeds which could lead to a delayed activation of the stick pusher in a flaps-extended configuration. This AD requires replacing each affected part with a serviceable part, and also prohibits the installation of affected parts, 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.

Leonardo S.p.a. Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model A109E, A109K2, A109S, AB412, AB412 EP, AB139, and AW139 helicopters. This AD was prompted by a report that certain rescue hoist cable assemblies may be equipped with a defective ball end. This AD requires inspecting certain rescue hoist cable assemblies and, depending on the results, replacing the rescue hoist cable assembly. This AD also allows installing certain rescue hoist cable assemblies and certain rescue hoists provided its 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.

Airbus Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332L, AS332L1, AS 365 N3, SA-365C1, SA- 365C2, SA-365N, and SA-365N1 helicopters. This AD was prompted by a report that certain rescue hoist cable assemblies may be equipped with a defective ball end. This AD requires inspecting certain rescue hoist cable assemblies and, depending on the results, replacing the rescue hoist cable assembly.

Airbus Helicopters
The FAA is superseding Airworthiness Directive (AD) 2021-04- 18, which applied to Airbus Helicopters Model EC225LP helicopters. AD 2021-04-18 required repetitively inspecting the bearing in the swashplate assembly of certain main rotor (M/R) mast assemblies and, depending on the findings, replacing the M/R mast assembly. AD 2021-04- 18 also prohibited installing those M/R mast assemblies unless certain requirements were met. Since the FAA issued AD 2021-04-18, it was determined that additional M/R mast assemblies are affected by the same unsafe condition and that it is necessary to distinguish the affected part numbers between M/R mast assemblies and mast swashplate assemblies. This AD continues to require the actions specified in AD 2021-04-18 and adds additional part-numbered M/R mast assemblies and distinguishes the affected part numbers between M/R mast assemblies and mast swashplate assemblies, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also clarifies the possible consequences that could result from the unsafe condition and clarifies a requirement. The FAA is issuing this AD to address the unsafe condition on these products.

CFM International, S.A. Engines
The FAA is adopting a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) Model LEAP-1A and LEAP-1C engines. This AD was prompted by an investigation of an in-flight shut down event that revealed the aft arm of the high-pressure turbine (HPT) rotor interstage seal had failed. This AD requires removal from service and replacement of the HPT rotor interstage seal for LEAP-1A engines. Since the HPT rotor interstage seal part number is interchangeable between LEAP-1A and LEAP-1C engines, this AD also prohibits installation of these affected parts onto any LEAP-1A or LEAP-1C engine. The FAA is issuing this AD to address the unsafe condition on these products.

Austro Engine GmbH Engines
The FAA is superseding Airworthiness Directive (AD) 2023-20-03 for certain Austro Engine GmbH Model E4 and E4P engines. AD 2023-20-03 required repetitive engine oil analysis for aluminum content outside the acceptable limits and, if necessary, replacement of the pistons, piston rings, con-rods assembly, and crankcase or, as an alternative, replacement of the engine core. Since the FAA issued AD 2023-20-03, the manufacturer identified errors in the lists of affected engines and provided updated information, which prompted this AD. This AD retains the requirements of AD 2023-20-03, adds compliance times for additional affected engine serial numbers, and removes certain engine serial numbers from the applicability of the existing AD. The FAA is issuing this AD to address the unsafe condition on these products.
