✈️Proposed Airworthiness Directive for CFM Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) Model LEAP-1A23, LEAP-1A24, LEAP-1A24E1, LEAP-1A26, LEAP-1A26CJ, LEAP-1A26E1, LEAP-1A29, LEAP- 1A29CJ, LEAP-1A30, LEAP-1A32, LEAP-1A33, LEAP-1A33B2, and LEAP-1A35A engines. This proposed AD was prompted by a report of multiple aborted takeoffs and air turn-backs (ATBs) caused by high-pressure compressor (HPC) stall, which was induced by high levels of non-synchronous vibration (NSV). Additional manufacturer investigation revealed that wear on the No. 3 bearing spring finger housing can lead to high levels of NSV. This proposed AD would require initial and repetitive calculations of the levels of NSV, inspection of the stage 2 high- pressure turbine (HPT) nozzle assembly honeycomb and HPT stator stationary seal honeycomb and, depending on the results of the calculations and inspections, replacement of certain parts. This AD also requires replacement of certain No. 3 bearing spring finger housings at a certain time. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is withdrawing an NPRM that proposed to adopt a new airworthiness directive (AD) that would have applied to all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2F and ARRIUS 2R engines. The NPRM was prompted by a manufacturer investigation that revealed certain high-pressure (HP) turbine blades may contain non- compliant porosity rates due to a change in the manufacturing process. The NPRM would have required replacement of affected HP turbine blades. Since the NPRM was issued, further investigation and tests demonstrated that the non-compliant rate of porosity has no impact on the use limit of the affected parts and the FAA has determined that the unsafe condition no longer exists. Accordingly, the NPRM is withdrawn.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. The collection involves submission of an AC Form 8050-5, Dealer's Aircraft Registration Certificate Application, by companies or individuals to obtain a Dealer's Aircraft Registration Certificate, which allows operation of an aircraft in lieu of obtaining a permanent aircraft registration certificate. The information collection is necessary for a dealer to operate an aircraft without a permanent aircraft registration certificate.

This action reopens the comment period for notice published on May 9, 2025, titled "Experimental Aircraft All Makes and Models Program." The notice informed operators of certain experimental aircraft of a new program that enables certain pilots to receive authorization to act as pilot in command (PIC) of certain experimental aircraft by completing aircraft-specific ground and flight training without taking a practical test. The FAA implements this program in accordance with Section 806 of the FAA Reauthorization Act of 2024. The FAA is reopening the comment period to allow commenters an additional opportunity to provide feedback.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to revise and renew an information collection. The collection involves a security holder completing an AC Form 8050-98, Aircraft Security Agreement and returning a completed AC Form 8050-41, Notice of Recordation--Aircraft Security Conveyance with Part II--Release to the Civil Aviation Registry, Aircraft Registration Branch (Registry). The information is used to record a security interest in an aircraft and eligible engines, propellers, or spare part locations and release that interest when the debt is satisfied.
Learn More✈️Proposed Airworthiness Directive for De Havilland Aircraft Compliance
The FAA proposes to supersede Airworthiness Directive (AD) 2019-16-09, which applies to certain De Havilland Aircraft of Canada Limited Model DHC-8-400 series airplanes. AD 2019-16-09 requires one- time inspections for cracks and damage of the elevator power control unit (PCU) brackets and surrounding area, horizontal stabilizer rear spar, and elevator front spar, and related investigative and corrective actions if necessary. Since the FAA issued AD 2019-16-09, new findings have been reported as a result of maintenance activities and/or inspections. This proposed AD would continue to require certain actions in AD 2019-16-09, and would also require repeating the inspections one time and performing applicable on-condition actions, remove an airplane from the applicability, and provide optional terminating action for the repetitive inspections. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More🚁Airworthiness Directive for Bell Textron Helicopters - FAA Compliance
The FAA is adopting a new airworthiness directive (AD) for all Bell Textron Canada Limited (BTCL) Model 407 and 427 helicopters. This AD was prompted by a report that certain expandable blade bolts installed on the main rotor blade may not have received the correct heat treatment, which could result in stress corrosion cracking of the expandable blade bolts. This AD requires removing the expandable blade bolts from service and replacing them with a part eligible for installation. This AD also prohibits the installation of an affected expandable blade bolt on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More🚁New Airworthiness Directive for Airbus AS332L1 Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332L1 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. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️New Airworthiness Directive for Viking Air DHC-3 Inspections
The FAA proposes to supersede Airworthiness Directive (AD) 2022-23-08, which applies to all Viking Air Limited (Viking) Model DHC- 3 airplanes. AD 2022-23-08 requires a visual inspection of the stabilizer actuator to confirm that the stabilizer actuator lock ring is present, correctly seated in the groove in the upper housing, and engaged in the clamp nut, applicable corrective actions, application of a torque seal, and sending the inspection results to the FAA. This proposed AD would require repetitively inspecting the stabilizer actuator to confirm that the stabilizer actuator lock ring is present, correctly seated in the groove in the upper housing, and engaged in the clamp nut; taking applicable corrective actions; applying a witness mark (torque seal); and installing a secondary retention feature as terminating action for the repetitive inspections. This proposed AD would also prohibit the installation of any stabilizer actuator unless it is a serviceable part. The FAA is proposing this AD to address the unsafe condition on these products.
