Federal Aviation Administration July 20, 2023 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 767 airplanes. This AD was prompted by reports of inoperative manual and alternate horizontal stabilizer trim switches. This AD requires repetitive inspections for immersion of each limit switch and position transmitter module (LSPTM) and of the LSPTM electrical wiring, repetitive inspections for blockage of the drain holes and cleaning of each drain hole, repetitive inspections for loose or cracked leveling compound, and applicable on-condition actions. For certain airplanes, this AD also requires installing two new drain holes, performing repetitive inspections for blockage of the drain holes and cleaning each drain hole, and applicable on-condition actions. 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 Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by a report the engine fire extinguishing control and indication system did not illuminate correctly. This proposed AD would require installing a software update to the integrated cockpit control panel (ICCP) remote data concentrator (RDC), as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model GVII-G600 airplanes. This AD was prompted by an addition of a life limit in the Airworthiness Limitations Section (ALS) for GVII-G600 flap yokes. The life limit for the GVII-G600 flap yokes was informed by a GVII-G500 flap yoke failure that occurred during flight testing and, ultimately, resulted in additional test and analysis to establish more accurate life limits reflective of each model's design features and stress levels. The FAA is issuing this AD to require revising the existing ALS to prevent the GVII-G600 inboard flap yoke from remaining in service beyond its life limit. The FAA is issuing this AD to address the unsafe condition on these products.

This action amends Class E airspace extending upward from 700 feet above the surface for Greenville Municipal Airport, Greenville, ME, as a new instrument approach procedure has been designed for this airport. This action also updates the airport's existing extension.

This action establishes United States Area Navigation (RNAV) T-route T-388, in the vicinity of Port Heiden, AK, in support of a large and comprehensive T-route modernization project for the state of Alaska.

This action removes Jet Route J-590, amends Very High Frequency (VHF) Omnidirectional Range (VOR) Federal airways V-11 and V- 70, and establishes United States Area Navigation (RNAV) route T-365. The FAA is taking this action due to the planned decommissioning of the VOR portion of the Greene County, MS (GCV), VOR/Tactical Air Navigation (VORTAC) navigational aid (NAVAID). The Greene County VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.
