Federal Aviation Administration April 13, 2023 – Federal Register Recent Federal Regulation Documents

This notice announces the FAA's intent to designate Blue Aviation, LLC, Supplemental Type Certificate (STC) No. SA02238AT as abandoned and make the related engineering data available upon request. The FAA has received a request to provide engineering data concerning this STC. The FAA has been unsuccessful in contacting Blue Aviation, LLC, concerning the STC. This action is intended to enhance-aviation safety.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This AD was prompted by reports of some passenger oxygen mask dispensing units (MDUs) with lanyards that are too long to meet the proper length specifications of the airplane. This AD requires replacing the affected MDUs with units that meet the proper length specifications, replacing the placards, and re-identifying the assemblies. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Galaxy airplanes and Model Gulfstream 200 airplanes. This AD was prompted by reports that wing flap fairing debonding and corrosion were discovered at certain areas of the lower skin on both wings. This AD requires an inspection for corrosion in certain areas of the wing skin fairings, additional inspections if necessary, resealing the fairings with new fillet seal, and applicable corrective actions, as specified in a Civil Aviation Authority of Israel (CAAI) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-401 and - 402 airplanes. This AD was prompted by an investigation of incorrectly manufactured sleeves that were potentially installed in the main landing gear (MLG) forward door linkage assembly. This AD requires review of technical records and inspections to determine if a discrepant sleeve is installed, replacement of any discrepant sleeve and re-identification of the MLG forward door linkage assembly. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B and GEnx-2B model turbofan engines. This proposed AD was prompted by a manufacturer investigation that revealed that certain stages 6-10 compressor rotor spools and forward seals were manufactured from powder metal material suspected to contain iron inclusion. This proposed AD would require the replacement of the affected stages 6-10 compressor rotor spools and forward seals. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2019-18- 07, which applied to certain Airbus SAS Model A319-111, -112, -113, - 114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, - 211, -212, -213, -231, and -232 airplanes. AD 2019-18-07 required repetitive rototest inspections of the open tack holes and rivet holes at the cargo floor support fittings of the fuselage, including doing all applicable related investigative actions and repair if necessary. AD 2019-18-07 also adds actions (modification) for certain airplanes. Since the FAA issued AD 2019-18-07, it was determined that certain airplanes need to do additional work. This AD continues to require the actions in AD 2019-18-07 and requires additional work for certain airplanes, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-202, -203, -223, and -243 airplanes; Model A330- 200 Freighter series airplanes; Model A330-300 series airplanes; Model A340-200 series airplanes; and Model A340-300 series airplanes. This AD was prompted by a report that damage was found to the firewall and fuselage skin in the auxiliary power unit (APU) compartment area on Model A330 airplanes. This AD requires replacing affected tee ducts with serviceable parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
