Document Number: 2023-06415
Type: Proposed Rule
Date: 2023-03-29
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to establish restricted areas R-5306G and R-5306H at Marine Corps Air Station (MCAS) Cherry Point, NC. The proposed restricted areas would overlie the amended restricted areas R- 5306C and R-5306D and the existing R-5306E. This action also proposes minor amendments of 2 latitude/longitude coordinates in R-5306C and R- 5306D to align with a refined 3 nautical mile boundary line off the coast, and controlling agency change for R-5306A, R-5306C, R-5306D, and R-5306E to MCAS Cherry Point CERAP. Due to altitude constraints, the existing restricted airspace structure around MCAS Cherry Point cannot fully support the training requirements for current 4th or 5th generation aircraft such as the F-18 and F-35. The proposed restricted areas would provide realistic training to enable pilots and aircrews to deliver real or simulated laser-guided precision guided munitions (PGM) from realistic altitudes.

Type: Proposed Rule
Date: 2023-03-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all CFM International, S.A. (CFM) 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 (LEAP-1A) model turbofan engines. This proposed AD was prompted by a manufacturer investigation that revealed that certain high-pressure turbine (HPT) rotor stage 1 disks (HPT stage 1 disks), forward outer seals, and stages 6-10 compressor rotor spools were manufactured from material suspected to have reduced material properties due to iron inclusion. This proposed AD would require replacement of certain HPT stage 1 disks, forward outer seals, and stages 6-10 compressor rotor spools. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2023-05710
Type: Proposed Rule
Date: 2023-03-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to remove Airworthiness Directive (AD) 92-02- 14, which applies to certain Airbus SAS Model A320 series airplanes. AD 92-02-14 was prompted by failure of the overwing emergency escape slides to deploy due to incorrect cable installations. AD 92-02-14 requires inspection for correct installation of the flexible control cables on the overwing emergency escape slides. AD 92-02-14 is no longer necessary because no new occurrences of incorrect cable installations have been reported, and existing maintenance activities are adequate to prevent new occurrences. Therefore, the FAA has determined that AD 92-02-14 is no longer necessary. Accordingly, the FAA proposes to remove AD 92-02-14.
