✈️New Airworthiness Directives for Pratt & Whitney Engines

The FAA is adopting a new airworthiness directive (AD) for certain Pratt & Whitney (PW) Model PW1519G, PW1521G, PW1521GA, PW1521G- 3, PW1524G, PW1524G-3, PW1525G, PW1525G-3, PW1919G, PW1921G, PW1922G, PW1923G, and PW1923G-A engines with a certain high-pressure compressor (HPC) 7th-stage axial rotor installed. This AD was prompted by an analysis of an event involving an International Aero Engines, LLC (IAE LLC) Model PW1127GA-JM engine, which experienced an HPC 7th-stage integrally bladed rotor (IBR-7) separation that resulted in an aborted takeoff. This AD requires performing initial and repetitive angled ultrasonic inspections (AUSI) of certain HPC 7th-stage axial rotors for cracks and replacing the HPC 7th-stage axial rotors if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

✈️Airworthiness Directives for CFM Engines

The FAA is adopting a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) Model LEAP-1A, LEAP-1B, and LEAP- 1C engines. This AD was prompted by a manufacturer investigation that revealed a quality escape for low-pressure turbine (LPT) disks made from forgings with nonconforming grain size. This AD requires removal and replacement of the LPT stage 4 and stage 5 disks. The FAA is issuing this AD to address the unsafe condition on these products.

✈️New FAA Airworthiness Directive for Boeing 737 Models

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by two engine fan blade- out (FBO) events that resulted in the separation of engine inlet cowl and fan cowl parts from the airplane damaging the fuselage, which caused loss of pressurization and subsequent emergency descent. The FBO events also resulted in cracks in the primary exhaust nozzle, potentially resulting in the departure of the primary exhaust nozzle and damaging a stabilizer or striking the fuselage and window. This AD requires an inspection or maintenance records check to determine if the primary exhaust nozzle has an affected part number and, for affected primary exhaust nozzles, an installation of bridge brackets onto the primary exhaust nozzle, or as an option, an installation of a serviceable primary exhaust nozzle. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.

✈️New Airworthiness Directive for Schempp-Hirth Gliders

The FAA is adopting a new airworthiness directive (AD) for certain Schempp-Hirth Flugzeugbau GmbH Model Duo Discus and Duo Discus T gliders. This AD was prompted by reports of gliders' canopies opening during air tow. This AD requires modifying the canopy locking mechanism. The FAA is issuing this AD to address the unsafe condition on these products.

✈️New FAA Airworthiness Directive for Airbus A330 Aircraft

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200, A330-200 Freighter, and A330-300 series airplanes. This AD was prompted by a report of contamination of the advanced pneumatic detector pressure switch of engine pylon fire detectors. This AD requires require replacement of the affected parts and prohibits 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.

✈️Proposed Airworthiness Directive for Airbus Canada Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This proposed AD was prompted by events where the cargo bottle fail caution message was displayed. This proposed AD would require replacing affected low rate discharge (LRD) bottles, inspecting extinguishing discharge lines and tubes, and replacing extinguishing discharge lines and tubes, as applicable, and would also prohibit the installation of affected LRD bottles, as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

✈️FAA Issues Airworthiness Directive for Airbus A330 Maintenance

The FAA is superseding Airworthiness Directive (AD) 2023-11- 08, which applied to all Airbus SAS Model A330-841 and -941 airplanes. AD 2023-11-08 required maintenance actions, including a high-pressure valve (HPV) seal integrity test, repetitive replacement of the HPV clips, revision of the existing airplane flight manual (AFM), and implementation of updates to the FAA-approved operator's minimum equipment list (MEL). This AD was prompted by the determination that the replacement intervals required by AD 2023-11-08 must be reduced to address the unsafe condition. This AD continues to require the actions in AD 2023-11-08. 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.

✈️Airworthiness Directive for ATR Airplanes Requiring Probe Replacement

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.
