Department of Transportation February 22, 2019 – Federal Register Recent Federal Regulation Documents

This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Denison Municipal Airport, Denison, IA. The FAA is proposing this action due to the decommissioning of the Denison non-directional radio beacon (NDB). Additionally, the geographic coordinates are being updated to coincide with the FAA's aeronautical database.

Under the Paperwork Reduction Act of 1995 (PRA) and its implementing regulations, FRA seeks approval of the Information Collection Requests (ICRs) abstracted below. Before submitting these ICRs to the Office of Management and Budget (OMB) for approval, FRA is soliciting public comment on specific aspects of the activities identified below.

The Board is granting an exemption for Kean Burenga (Burenga) and Chesapeake and Delaware, LLC (CAD), both noncarriers, to continue in control of Dover and Delaware River Railroad, LLC (DDRR), when DDRR becomes a Class III rail carrier in a related transaction involving DDRR's lease and operation of 27.2 miles of rail lines owned by Norfolk Southern Railway Company (NSR) and operation of 80.7 miles of rail lines pursuant to a trackage rights agreement among DDRR, New Jersey Transit Corporation, and NSR.\1\ All of the affected lines are located in the State of New Jersey. The lines over which DDRR will operate connect with lines operated by Dover and Rockaway River Railroad, LCC (Rockaway), another Class III carrier that CAD controls.\2\ Because all of the carriers involved are Class III carriers, this continuance-in- control exemption is not subject to labor protective conditions.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports of low clearance between the variable frequency generator (VFG) power feeder cables and adjacent hydraulic lines and/or fuel lines in the aft equipment bay, which could cause chafing damage. This proposed AD would require modifying the routing of the VFG power feeder cables and harnesses in the aft equipment bay. We are proposing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-300, -400, and -500 series airplanes. This AD was prompted by a report indicating the passenger service units (PSUs) became separated from their attachments during several survivable accident sequences. This AD requires installing lanyard assemblies on the PSU and, for certain airplanes, on the life vest panel. We are issuing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2017-16-05, which applied to certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2017-16-05 required a one- time detailed visual inspection for discrepancies in the Krueger flap bullnose attachment hardware, and related investigative and corrective actions if necessary. This AD adds airplanes and an additional inspection to determine if any Krueger flap no. 1, 2, 3, or 4 has been replaced, and related investigative and corrective actions. Since this is a rotable parts issue, the applicability of this AD has been expanded beyond the airplanes listed in the related service bulletin to include all airplanes on which a Krueger flap bullnose may be installed. This AD was prompted by a report of a Krueger flap bullnose departing an airplane during taxi, which caused damage to the wing structure and thrust reverser, and a report of a missing no. 2 Krueger flap bullnose hinge bolt from an airplane that was not included in the effectivity of AD 2017-16-05. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A310-304, -322, -324, and -325 airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that certain wing skin stringer joints are subject to widespread fatigue damage (WFD). This AD requires a rototest inspection of the fastener holes in the affected areas and repair if necessary, and modifying the fastener holes. We are issuing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-200, -200C, -300, -400, and -500 airplanes. This proposed AD was prompted by reports of cracking in the lower lobe skin panel assemblies of the fuselage. This proposed AD would require replacement of lower lobe skin panel assemblies, and detailed inspections for scribe lines and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.
