Airworthiness Directives; Pratt & Whitney Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all Pratt & Whitney (PW) Model PW2037, PW2037M, and PW2040 engines with a certain high-pressure turbine (HPT) 2nd stage blade assembly installed. This proposed AD was prompted by an in-flight shutdown (IFSD) caused by the fracture of HPT 2nd stage turbine hub assembly lugs, which resulted in blade liberation and a titanium fire in the high-pressure compressor (HPC). This proposed AD would require a visual inspection of the HPT 2nd stage blade assemblies for missing contact marks, a dimensional shadowgraph inspection of the HPT 2nd stage blade assemblies for blade root profile dimensional inspection, and an eddy current inspection (ECI) of the HPT 2nd stage turbine hub assembly for conforming slot flatness. This proposed AD would also require removal and replacement of any HPT 2nd stage turbine hub assembly or HPT 2nd stage blade assembly that does not pass any inspection. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-8 and 747-8F series airplanes. This proposed AD was prompted by a report that all six Integrated Display Units (IDUs) became blank when new flight plan data was entered in the Flight Management System (FMS), and by a determination that indication of decaying airspeed in certain scenarios is required. This proposed AD would require installing updated software. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA is revising a notice of proposed rulemaking (NPRM) that would have applied to certain Airbus SAS Model A319-115 airplanes; Model A320-214, -216, -232, -251N, and -271N airplanes; and Model A321- 211, -231, -251N, -251NX, -252NX, -253N, -253NX, -271N, -271NX, and - 272N airplanes. This action revises the NPRM by adding Model A321-213 airplanes, which were inadvertently left out of the applicability. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, the FAA is requesting comments on this SNPRM.
Agency Information Collection Activities: Requests for Comments; Clearance of Renewed Approval of Information Collection: Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) Monitoring, Reporting, and Verification (MRV) Program
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 for a renewed information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on January 25, 2023. FAA received two comments to this notice. The collection involves a request that airplane operators subject to the applicability of Annex 16, Volume IV of the Convention on Civil Aviation (hereinafter the ``Chicago Convention'') submit electronically an Emissions Monitoring Plan (EMP), an annual Emissions Report (ER), and an optional annual ER CORSIA Eligible Fuels Annex (CEFA) to the FAA. The information to be collected is necessary because FAA will use the information to fulfill the United States' responsibilities under the Chicago Convention.
Airspace Designations; Incorporation by Reference
This action amends 14 CFR part 71 relating to airspace designations to reflect the approval by the Director of the Federal Register of the incorporation by reference of FAA Order JO 7400.11H, Airspace Designations and Reporting Points. This action also explains the procedures the FAA will use to amend the listings of Class A, B, C, D, and E airspace areas; air traffic service routes; and reporting points incorporated by reference.
