Federal Aviation Administration October 4, 2023 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model CF6-80C2B1F, CF6-80C2B2F, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6F, CF6-80C2B7F, and CF6-80C2K1F engines. This AD was prompted by an uncontained engine fire and consequent manufacturer investigation, which revealed that certain bearings were installed improperly. This AD requires inspection of the magnetic chip detector (MCD) probe tip for metallic particles and, if necessary, removal of the engine from service. The FAA is issuing this AD to address the unsafe condition on these products.

This action extends the comment period for the NPRM titled ``Modernization of Special Airworthiness Certification,'' that was published on July 24, 2023. In that document, the FAA proposed to amend rules for the manufacture, certification, operation, maintenance, and alteration of light-sport aircraft. The proposed amendments would enable enhancements in safety and performance and would increase privileges under a number of sport pilot and light-sport aircraft rules. These enhancements include increasing suitability for flight training, limited aerial work, and personal travel. This proposed rule would expand what aircraft sport pilots may operate. The NPRM also proposed to amend the special purpose operations for restricted category aircraft; amend the duration, eligible purposes, and operating limitations for experimental aircraft; and add operating limitations applicable to experimental aircraft engaged in space support vehicle flights to codify statutory language. The FAA is extending the comment period for this NPRM to allow commenters additional time to analyze the proposed rule and prepare a response.

This action proposes to amend Very High Frequency Omnidirectional Range (VOR) Federal airway V-9 in Arkansas. V-9 currently exists as three separate route segments, and this proposed amendment would connect two of the route segments to create a longer contiguous airway.
