✈️FAA Issues Airworthiness Directive for Embraer Airplanes

The FAA is adopting a new airworthiness directive (AD) for all Embraer S.A. Model EMB-135ER, -135KE, -135KL, and -135LR airplanes; and Model EMB-145, -145EP, -145ER, -145LR, -145MP, -145MR, and -145XR airplanes. This AD was prompted by a structural assessment that indicated certain central fuselage longitudinal splices are subjected to fatigue damage on multiple sites due to loose fasteners, which may reduce the structural residual strength below the required levels. This AD requires performing repetitive inspections of certain upper central fuselage longitudinal splices and reporting the inspection results, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. This AD also requires performing corrective actions if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

🛩️New FAA Airworthiness Directive for Britten-Norman Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Britten-Norman Aerospace Ltd. Model BN-2, BN-2A, BN-2A-2, BN- 2A-3, BN-2A-6, BN-2A-8, BN-2A-9, BN-2A-20, BN-2A-21, BN-2A-26, BN-2A- 27, BN-2B-20, BN-2B-21, BN-2B-26, BN-2B-27, BN-2T, BN2T-4R, and BN2T-4S airplanes; and certain Model BN2A MK. III, BN2A MK. III-2, and BN2A MK. III-3 airplanes. This AD was prompted by the determination that, in order to ensure the continued structural integrity of certain landing gear and associated components, it is necessary to require removal of these components from service prior to exceeding established fatigue lives. This AD requires determining the number of landings on affected main landing gears (MLGs), nose landing gears (NLGs), and associated components; removing from service any part that has reached or exceeded the established fatigue life and installing a replacement part; and prohibiting the installation of any affected part unless the number of landings for that part is below the established fatigue life. The FAA is issuing this AD to address the unsafe condition on these products.

✈️FAA Withdraws Proposed Rule on Boeing Airworthiness Directives

The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to supersede Airworthiness Directive (AD) 2023-08-04, which applies to certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. The NPRM was prompted by reports of a loss of water pressure during flight and water leaks that affected multiple pieces of electronic equipment, and by the discovery that some clamshell couplings did not have the required safety strap. The NPRM would have required inspecting all door 1 and door 3 lavatory and galley potable water systems for missing or incorrectly installed clamshell couplings, inspecting all clamshell couplings for the presence and correct installation of safety straps at door 1 and door 3 lavatories and galleys with a potable water system, and performing applicable on- condition actions. The NPRM would have also prohibited the installation of affected parts at inspection locations and removed Model 787-10 airplanes from the applicability. Since issuance of the NPRM, the FAA has determined that the identified service information may not adequately address the unsafe condition on one of the galleys, and Model 787-10 airplanes should be included in the applicability. Accordingly, the NPRM is withdrawn.

✈️FAA Issues Airworthiness Directive for Bombardier Airplanes

The FAA is superseding Airworthiness Directive (AD) 2021-10- 02, which applied to all Bombardier, Inc., Model BD-700-1A10 and BD- 700-1A11 airplanes. AD 2021-10-02 required repetitive general visual inspections of the left- and right-hand elevator torque tube bearings for any sand, dust, or corrosion; repetitive functional tests of the elevator control system; and replacement of the elevator torque tube bearings if necessary. This AD continues to require certain actions in AD 2021-10-02 and requires revising the existing maintenance or inspection program, as applicable, to incorporate a new airworthiness limitation. This AD was prompted by a determination that a new airworthiness limitation is necessary. The FAA is issuing this AD to address the unsafe condition on these products.

✈️New Airworthiness Directive for CFM Engines by FAA

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.

✈️Airworthiness Directive on Boeing 767

The FAA is superseding Airworthiness Directive (AD) 2019-14- 13, which applies to all The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. AD 2019-14-13 required identifying the part number, and the serial number if applicable, of the Captain's and First Officer's seats, and performing applicable on-condition actions for affected seats. AD 2019-14-13 also required a one-time detailed inspection and repetitive checks of the horizontal movement system (HMS) of the Captain's and First Officer's seats, and applicable on- condition actions. AD 2019-14-13 also provided an optional terminating action for the repetitive actions for certain seats. This AD was prompted by reports of uncommanded fore and aft movement of the Captain's and First Officer's seats. This AD retains the actions in AD 2019-14-13 and adds an inspection of previously omitted part numbers. The FAA is issuing this AD to address the unsafe condition on these products.
