✈️FAA Introduces New Airworthiness Directive for Leonardo Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model A109C, A109E, A109S, and AW109SP helicopters. This AD was prompted by a report of a quality escape on a batch of main rotor blades (MRBs). This AD requires repetitively tap inspecting certain MRBs and replacing those MRBs. This AD also prohibits installing those MRBs, 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.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332L helicopters. This AD was prompted by a determination that new or 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, 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.

The FAA is superseding Airworthiness Directive (AD) 2020-20-17 and AD 2021-15-05 for all General Electric Company (GE) Model GE90- 110B1 and GE90-115B engines. AD 2020-20-17 prohibits dispatch of an airplane if certain status messages are displayed on the engine indicating and crew alerting system (EICAS) and if certain conditions are present; and as terminating action, requires revision of the existing FAA-approved minimum equipment list (MEL) by incorporating the dispatch restrictions into the MEL. AD 2021-15-05 requires initial and repetitive replacement of the full authority digital engine control (FADEC) integrated circuit (MN4) microprocessor. Since the FAA issued AD 2020-20-17 and AD 2021-15-05, the manufacturer has developed a software revision for the electronic engine control (EEC) FADEC that further mitigates the unsafe condition. This AD retains all the actions of AD 2020-20-17 and AD 2021-15-05, and also requires upgrading the EEC FADEC software to an EEC FADEC software version eligible for installation as a terminating action. 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 The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by a report of under-torqued and missing nuts on the horizontal stabilizer trim actuator (HSTA) lower gimbal assembly. This proposed AD would require a review of maintenance records to determine if an overhauled HSTA was inspected and corrective actions were accomplished using certain service information, and applicable on-condition actions. 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 The Boeing Company Model 737-700, 737-800, 737-900, 737- 900ER, 737-8, and 737-9 series airplanes. This proposed AD was prompted by a report of a passenger being unable to exit the lavatory during flight due to a broken latch that prevented toggling of the lock. This proposed AD would require replacing lavatory bifold door latches with latches having an improved design. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.

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.
Learn More✈️FAA Proposes Airworthiness Directive for Airbus A350 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by reports that certain lower torque links of the nose landing gear (NLG) were manufactured without bright shot peening; the omission of bright shot peening could result in reduced fatigue life of the parts. This proposed AD would require replacement of affected parts before exceeding their reduced life limit and limit the installation of affected parts, 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.
Learn More✈️FAA Proposes Airworthiness Directive for Boeing 757 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757 airplanes. This proposed AD was prompted by reports of precoolers that failed due to a wear-out condition, combined with latently failed overheat detection thermal switches. This proposed AD would require an inspection for heat damage on the engine strut structure, repetitive tests of the thermal switch temperature and ground wires, replacement of the precooler on Model 757-300 airplanes, and applicable on-condition actions. 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 Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by a report that incorrect information was found in certain calculation tables in a section of the airplane flight manual (AFM) that addresses certain slat-flap conditions. This proposed AD would require revising the Non-Normal Procedures section of the existing AFM to provide the flightcrew with corrected procedures to use in certain slat-flap conditions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2022-24-06 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model BR700- 710A1-10, BR700-710A2-20, and BR700-710C4-11 engines. AD 2022-24-06 required initial and repetitive visual inspections of certain low- pressure compressor (LPC) rotor (fan) disks and replacement of any LPC rotor (fan) disk with cracks detected. AD 2022-24-06 also allows for modification of the engine in accordance with RRD service information as a terminating action to these inspections. Since the FAA issued AD 2022-24-06, the manufacturer published updated service information and revised the engine maintenance manual (EMM) to provide instructions for an improved ultrasonic inspection method, which prompted this AD. This AD requires initial and repetitive visual inspections of certain LPC rotor (fan) disks and replacement of any LPC rotor (fan) disk with cracks detected and would allow modification of the engine as a terminating action to the inspections, 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.
