Federal Aviation Administration January 12, 2022 – Federal Register Recent Federal Regulation Documents

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 reinstate with change an information collection used to support the analysis of safety data as part of the Safety Management System requirement for part 121 certificate holders. The information collected will be used to identify hazards and show ongoing compliance with part 5, Safety Management Systems.

The FAA proposes to supersede Airworthiness Directive (AD) 2020-23-07, which applies to certain Leonardo S.p.a. Model AB139 and AW139 helicopters. AD 2020-23-07 requires removing certain life raft reservoirs (reservoirs) from service, inspecting the reservoirs and actuator cables, and depending on the inspection results, replacing the reservoir or adjusting the actuator cable. Since the FAA issued AD 2020-23-07, additional serial-numbered reservoirs were identified as also being affected by the unsafe condition. This proposed AD would retain certain requirements of AD 2020-23-07, expand the required actions to include additional serial-numbered reservoirs, and update applicable service information. The FAA is proposing this AD to address the unsafe condition on these products.

These special conditions are issued for a supplemental type certificate on certain transport category airplanes. These airplanes, as modified by Learjet, Inc. (Learjet), 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 the installation of a system that allows connection to airplane electronics and networks, and access from aircraft external sources (e.g., operator networks, wireless devices, internet connectivity, service provider satellite communications, electronic flight bags, etc.) to the previously isolated airplane 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.

The FAA is adopting a new airworthiness directive (AD) for certain Pratt & Whitney (P&W) PW1500G and PW1900G model turbofan engines. This AD was prompted by an analysis of an event involving an International Aero Engines AG (IAE) V2533-A5 model turbofan engine, which experienced an uncontained failure of a high-pressure turbine (HPT) 1st-stage disk that resulted in high-energy debris penetrating the engine cowling. This AD requires removing certain HPT 1st-stage and HPT 2nd-stage disks from service and replacing with parts eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
