Department of Transportation June 15, 2016 – Federal Register Recent Federal Regulation Documents

FMCSA announces its decision to renew the exemptions from the vision requirement in the Federal Motor Carrier Safety Regulations for 120 individuals. FMCSA has statutory authority to exempt individuals from the vision requirement if the exemptions granted will not compromise safety. The Agency has concluded that granting these exemption renewals will provide a level of safety that is equivalent to or greater than the level of safety maintained without the exemptions for these commercial motor vehicle (CMV) drivers.

This action clarifies the FAA's policy regarding storage of non-aeronautical items in airport facilities designated for aeronautical use. Under Federal law, airport operators that have accepted federal grants and/or those that have obligations contained in property deeds for property transferred under various Federal laws such as the Surplus Property Act generally may use airport property only for aviation-related purposes unless otherwise approved by the FAA. In some cases, airports have allowed non-aeronautical storage or uses in some hangars intended for aeronautical use, which the FAA has found to interfere with or entirely displace aeronautical use of the hangar. At the same time, the FAA recognizes that storage of some items in a hangar that is otherwise used for aircraft storage will have no effect on the aeronautical utility of the hangar. This action also amends the definition of aeronautical use to include construction of amateur-built aircraft and provides additional guidance on permissible non- aeronautical use of a hangar.''

On March 15, 2016, FRA published a Notice of Proposed Rulemaking (NPRM) that would require establishing minimum requirements for the size of train crew staffs depending on the type of operation. FRA is announcing a public hearing to provide interested persons an opportunity to provide oral comments on the proposal. FRA is also announcing a reopening of the comment period for this proceeding to allow time for interested parties to submit written comments in response to views or information provided at the public hearing.

This document provides the public with notice that the Port Authority Trans-Hudson Corporation (PATH) submitted to FRA its Positive Train Control Safety Plan (PTCSP), Revision 3.0, dated March 23, 2016. PATH asks FRA to approve its PTCSP and issue a Positive Train Control (PTC) System Certification for PATH's Communication Based Train Control (CBTC) system, under Title 49 Code of Federal Regulations (CFR) 236.1009, Procedural requirements, and 236.1015, PTC Safety Plan content requirements and PTC System Certification. This notice was assigned to Docket Number FRA-2010-0034.

This document announces an extension of the comment period for the above-referenced NPRM, which proposed the adoption of a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes), and Model A310 series airplanes. That NPRM invited comments concerning the proposed requirement to modify the fuel quantity indicating system (FQIS) to prevent development of an ignition source inside the center fuel tank due to electrical fault conditions. This extension of the comment period is necessary to provide all interested persons an opportunity to present their views on the proposed requirements of that NPRM.

This document announces an extension of the comment period for the above-referenced NPRM, which proposed the adoption of a new airworthiness directive (AD) for certain The Boeing Company Model 737- 600, -700, -700C, -800, -900, and -900ER series airplanes. That NPRM invited comments concerning the proposed requirement to modify the fuel quantity indicating system (FQIS) to prevent development of an ignition source inside the center fuel tank due to electrical fault conditions. This extension of the comment period is necessary to provide all interested persons an opportunity to present their views on the proposed requirements of that NPRM.

We are adopting a new airworthiness directive (AD) for GROB Aircraft AG Model G115EG airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks in the bonded joint of the rear horizontal stabilizer frame. We are issuing this AD to require actions to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2014-15-04 for certain Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. AD 2014- 15-04 required deactivating the potable water system, or alternatively filling and activating the potable water system. This new AD requires inspecting the in-line heater for correct brazing and corrective action if needed, and installing a shrinkable tube on the water line and a spray shield on the in-line heater. This AD was prompted by a report of rudder pedal restriction which was the result of water leakage at the inlet tubing of an in-line heater in the lower part of the forward fuselage. This AD was also prompted by the development of a modification that would address the unsafe condition. We are issuing this AD to prevent rudder pedal restriction due to the pitch control mechanism becoming frozen as the result of water spray, which could prevent disconnection of the pitch control mechanism and normal pitch control, and consequently result in reduced controllability of the airplane.
