Learn More🚁Proposed Airworthiness Directive for Airbus Helicopters AS332L1
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS332L1 helicopters. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require 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 proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️New FAA Airworthiness Directive on Pratt & Whitney Canada Engines
The FAA is adopting a new airworthiness directive (AD) for certain Pratt & Whitney Canada Corp. (P&WC) Model PW535E and PW535E1 engines. This AD was prompted by a manufacturer design review that indicated certain flange bolts securing the gas generator case and turbine support case are susceptible to cracking at their current low- cycle fatigue (LCF) life. This AD requires repetitive borescope inspections (BSI) of the gas generator case to turbine support case retaining bolts for evidence of bolt cracks, bolt fracture, missing bolts, or loose bolts and replacement, if necessary, 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.

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.

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes. This AD was prompted by a report of a 5-inch crack on the upper wing skin at a certain wing station of the right wing. This AD requires repetitive inspections for cracking of the upper wing skin common to certain fasteners and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.

The Environmental Protection Agency (EPA) is taking final action to approve a revision to the Feather River Air Quality Management District (FRAQMD or "District") portion of the California State Implementation Plan (SIP). This revision concerns recodification of certain rules to replace historical Sutter County Air Pollution Control District and Yuba County Air Pollution Control District rules with the corresponding FRAQMD rules. These rules regulate pollutants under the Clean Air Act (CAA or "Act").
Learn More✈️FAA Proposes Airworthiness Directive for Airbus A350-941 and -1041
The FAA proposes to supersede Airworthiness Directive (AD) 2020-03-14, which applies to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-03-14 requires an inspection of affected crew oxygen cylinder assemblies for any discrepancy and replacement of discrepant crew oxygen cylinder assemblies with serviceable parts, and allows installation of affected parts under certain conditions. Since the FAA issued AD 2020-03-14, the supplier introduced an improved oxygen cylinder assembly, that will ensure the correct function of the system. This proposed AD would continue to require the actions in AD 2020-03-14 and would require replacement of all affected parts with redesigned parts and would also prohibit 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 Airworthiness Directive
The FAA is adopting a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This AD was prompted by a report of a manufacturing defect identified in the lavatory fire extinguisher. This defect could potentially result in leakage at the eutectic tip, leading to a loss of pressure in the cylinder, making fire extinguishing capabilities ineffective. This AD requires an inspection (i.e., weight check) and replacement, as applicable, of certain lavatory compartment fire extinguishers, and also prohibits the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️New Airworthiness Directive Impacts Airbus Canada Airlines
The FAA is adopting a new airworthiness directive (AD) for all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. This AD was prompted by a design review that discovered software protection logic for potential large leaks from the engine bleed duct inside the engine core compartments was partially impaired. This AD requires revising the existing airplane flight manual (AFM) to incorporate the procedures for the flightcrew to manually isolate the opposite functional engine in the event of an engine bleed duct large leak condition, as specified in a Transport Canada AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
