Department of Transportation February 26, 2020 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports that main landing gear (MLG) trailing arm assemblies were found with compromised paint finish and corrosion on the axle bore inner diameters due to improper removal of contaminants during manufacturing. This AD requires a one-time inspection to determine if an affected MLG trailing arm assembly is installed, repetitive detailed inspections of the inner diameter of the affected MLG trailing arm assembly axle bore for surface finish discrepancies, corrective actions if necessary, and eventual replacement of primer and paint and application of corrosion preventive compound on the inner diameter of all affected MLG trailing arm assembly axle bores, which terminates the repetitive inspections. 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 The Boeing Company Model 737-8 and 737-9 airplanes. This proposed AD was prompted by a report that certain exterior fairing panels on the top of the engine nacelle and strut (the thumbnail fairing and mid strut fairing panels) may not have the quality of electrical bonding necessary to ensure adequate shielding of the underlying wiring from the electromagnetic effects of lightning strikes or high intensity radiated fields (HIRF), which could potentially lead to a dual engine power loss event from a critical lightning or HIRF exposure event. This proposed AD would require a detailed inspection of the thumbnail fairing panels and mid strut fairing panels for excessive rework of the metallic (aluminum foil) inner surface layer, replacement of any excessively reworked panels, and modification of the thumbnail fairing assembly to ensure adequate bonding. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for Leonardo S.p.A. Model AW189 helicopters. This AD requires inspecting the hydraulic fluid level on each tail rotor (T/R) damper and depending on the inspection results, removing the T/R damper from service and reporting information or repetitively inspecting the T/R damper. This AD is prompted by reports of major leakage of hydraulic fluid in T/R dampers. This condition could result in degradation of T/R damper performance; multiple leaking T/R dampers could result in T/R damage and subsequent loss control of the helicopter. The actions of this AD are intended to address an unsafe condition on these products.

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet series 100 & 440) airplanes. As published, paragraph (h)(2) of that AD specifies an incorrect service information reference for performing the inspection. This document corrects that error. In all other respects, the original document remains the same.

This action proposes to amend the Class E airspace extending upward from 700 feet above the surface at Muhlenberg County Airport, Greenville, KY, and Madisonville Regional Airport, Madisonville, KY. The FAA is proposing this action as the result of the decommissioning of the Central City VHF omnidirectional range (VOR) navigation aid, which provided navigation information for the instrument procedures at these airports, as part of the VOR Minimum Operational Network (MON) Program. Additionally, the name of Madisonville Regional Airport and the geographic coordinates of both airports would be updated to coincide with the FAA's aeronautical database.

Federal public transportation law delegated to the Federal Transit Administrator permits the Administrator of the Federal Transit Administration (FTA) to authorize a recipient of FTA funds to transfer land or a facility to a public body for any public purpose with no further obligation to the Federal Government (the Government) if, among other things, no Federal agency is interested in acquiring the asset for Federal use. Accordingly, FTA is issuing this Notice to advise Federal agencies that the Northeast Illinois Regional Commuter Railroad Corporation a/k/a Metra (Metra) intends to transfer the land and building located at 16912 and 16901 Paulina Avenue (respectively), Hazel Crest, Illinois (Subject Property) to the Village of Hazel Crest (Village). Metra used the location as a Passenger Assistance Link building and storage facility from 1987 to the present (33 years). Metra has determined it no longer needs the building for public transportation purposes. The Village plans to utilize the Subject Property as a job training center for the community. The Village hopes to partner with another unit of government and/or local college to equip the building with technology equipment and staff it with career development experts who would be dedicated to helping career seekers find employment in the region.
