Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports of ram air turbine (RAT) pump barrel assembly failures, which caused the RAT to fail to provide hydraulic power. The failures were determined to be caused by variations in the bronze metal used during manufacturing, which can result in varying fatigue properties. This proposed AD would require an inspection or records review to determine the part number of the RAT pump and control module (PCM) and of the RAT assembly, and replacement of any RAT PCM or any RAT assembly having certain part numbers. 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.
Recognition of Pilot in Command Experience in the Military and Air Carrier Operations
This final rule provides additional crediting options for certain pilot in command (PIC) time to count towards the 1,000 hours of air carrier experience required to serve as a PIC in air carrier operations. In addition, this final rule allows credit for select military time in a powered-lift flown in horizontal flight towards the 250 hours of airplane time as PIC, or second in command (SIC) performing the duties of PIC, required for an airline transport pilot (ATP) certificate. This action is necessary to expand opportunities for pilots that meet the amended criteria to use relevant flight experience toward the requirements for an ATP certificate and to meet PIC qualification requirements for air carrier operations.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for all General Electric Company (GE) GE90-110B1 and GE90-115B model turbofan engines and certain GE90-76B, GE90-85B, GE90-90B, and GE90-94B model turbofan engines. This AD was prompted by the detection of melt-related freckles in the forgings and billets, which may reduce the life of certain rotating compressor discharge pressure (CDP) high-pressure turbine (HPT) seals (rotating CDP seals), interstage HPT rotor seals, and HPT rotor stage 2 disks. This AD requires revising the airworthiness limitations section (ALS) of the applicable GE90-100 Engine Manual (EM) and the operator's existing approved maintenance program or inspection program, as applicable, to incorporate reduced life limits for these parts. This AD also requires the removal and replacement of certain interstage HPT rotor seals, identified by serial number (S/N), installed on GE90-76B, GE90-85B, GE90-90B, and GE90-94B model turbofan engines. The FAA is issuing this AD to address the unsafe condition on these products.
Notice of Receipt and Request for Review of Noise Compatibility Program
The Federal Aviation Administration (FAA) announces that it is reviewing a proposed noise compatibility program that was submitted for John F. Kennedy International Airport by The Port Authority of New York and New Jersey. This program was submitted subsequent to a determination by FAA that associated noise exposure maps submitted for John F. Kennedy International Airport were in compliance with applicable requirements, effective May 19, 2017. The proposed noise compatibility program will be approved or disapproved on or before March 15, 2023. This notice also announces the availability of this noise compatibility program for public review and comment.
Special Conditions: L2 Consulting Services, Inc., Bombardier Model CL-600-2B16 (604 Variant) Airplane; Electronic System Security Protection From Unauthorized External Access
These special conditions are issued for the Bombardier Model CL-600-2B16 (604 variant) airplane. This airplane, as modified by L2 Consulting Services, Inc., will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for airplanes. This design feature is associated with the installation of an electronic network system architecture that will allow increased connectivity to and access from external network sources, (e.g., operator networks, wireless devices, internet connectivity, service provider satellite communications, electronic flight bags, etc.) to the airplane's previously isolated electronic assets (networks, systems, and databases). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Special Conditions: L2 Consulting Services, Inc., Bombardier Model CL-600-2B16 (604 Variant) Airplane; Electronic System Security Protection From Unauthorized Internal Access
These special conditions are issued for the Bombardier Model CL-600-2B16 (604 variant) airplane. This airplane, as modified by L2 Consulting Services, Inc., will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is associated with the installation of a digital system that contains a wireless and hardwired network with hosted application functionality that allows access, from sources internal to the airplane, to the airplane's internal electronic components. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
