Department of Transportation January 5, 2017 – Federal Register Recent Federal Regulation Documents

The Saint Lawrence Seaway Development Corporation (SLSDC) and the St. Lawrence Seaway Management Corporation (SLSMC) of Canada, under international agreement, jointly publish and presently administer the St. Lawrence Seaway Regulations and Rules (Practices and Procedures in Canada) in their respective jurisdictions. Under agreement with the SLSMC, the SLSDC is amending the joint regulations by updating the Seaway Regulations and Rules in various categories. The changes will update the following sections of the Regulations and Rules: Condition of Vessels; Seaway Navigation; Radio Communications; General; and, Vessels Transiting U.S. Waters. These amendments are necessary to take account of updated procedures and will enhance the safety of transits through the Seaway. Several of the amendments are merely editorial or for clarification of existing requirements.

The Department of Transportation is directing all interested persons to show cause why it should not issue an order finding Galaxy Air Services FBO, LLC d/b/a Texas Air Shuttle fit, willing, and able, and awarding it a Commuter Air Carrier Authorization.

The Department of Transportation is directing all interested persons to show cause why it should not issue an order finding Aztec Worldwide Airlines, Inc., fit, willing, and able, to provide scheduled passenger service as a commuter air carrier using small aircraft pursuant to Part 135 of the Federal Aviation Regulations, and awarding it a Commuter Air Carrier Authorization.

As part of its continuing effort to reduce paperwork burdens, and as required by the Paperwork Reduction Act of 1995 (PRA), the Surface Transportation Board (STB or Board) gives notice that it is requesting from the Office of Management and Budget (OMB) approval of a new collection to implement a directive of the Fixing America's Surface Transportation Act of 2015, FAST Act). Title XI of the FAST Act, entitled ``Passenger Rail Reform and Investment Act of 2015,'' gives the Board jurisdiction to resolve cost allocation and access disputes between National Railroad Passenger Corporation (Amtrak), the states, and potential non-Amtrak operators of intercity passenger rail service. The FAST Act directs the Board to establish procedures for the resolution of these disputes, ``which may include the provision of professional mediation services.'' The Board adopted final rules to implement these procedures in Dispute Resolution Procedures Under the Fixing America's Surface Transportation Act of 2015, EP 734 (STB served Nov. 29, 2016). Due to a technical omission in the notice of proposed rulemaking in EP 734 under the PRA, the Board is seeking OMB approval for this collection in this notice.

This action establishes one low altitude Area Navigation (RNAV) T-route in the western United States. The route establishes a transition from the San Diego area to points east. This route promotes operational efficiencies for users and provides connectivity to current and proposed RNAV en route and terminal procedures.

We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, AS332L2, and EC225LP helicopters. This proposed AD would require repetitive inspections of the intermediate gear box (IGB) fairing. This proposed AD is prompted by separation of the IGB fairing from the fairing gutter and subsequent interference with the drive shaft. The actions of this proposed AD are intended to prevent the unsafe condition on these products.

These special conditions are issued for the Cessna Aircraft Company model 525 airplane. This airplane as modified by Cranfield Aerospace Limited will have a novel or unusual design feature associated with the installation of a Tamarack Active Technology Load Alleviation System and Cranfield Winglets. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

We propose to adopt a new airworthiness directive (AD) for certain CFE Company (CFE) turbofan engines. This proposed AD was prompted by a quality escape for high-pressure compressor (HPC) impellers made from forgings with nonconforming material grain size. This proposed AD would require removal of the HPC impeller. We are proposing this AD to correct the unsafe condition on these products.

We propose to supersede airworthiness directive (AD) 93-17-13 for Schweizer Aircraft Corporation and Hughes Helicopters, Inc. (now Sikorsky Aircraft Corporation) (Sikorsky) Model TH55A, 269A, 269A-1, 269B, and 269C helicopters. AD 93-17-13 requires installing tachometer markings and inspecting the driveshaft. This proposed AD would require recurring inspections of the driveshaft and would expand the applicability to include Model 269C-1 helicopters. This proposed AD is prompted by reports of accidents because of driveshaft failures. The actions of this proposed AD are intended to prevent the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2014-22-01 for all PILATUS AIRCRAFT LTD. Models PC-12, PC-12/45, PC-12/47, and PC-12/ 47E airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a need to incorporate new revisions into the Limitations section, Chapter 4, of the FAA-approved maintenance program (e.g., maintenance manual). The limitations were revised to include repetitive inspections of the main landing gear (MLG) attachment bolts. We are issuing this AD to require actions to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, CN- 235-300, and C-295 airplanes. This proposed AD was prompted by reports of excessive play between bushings and their respective fitting housings at certain elevator fittings. This proposed AD would require a one-time detailed inspection and repetitive eddy current inspections of the elevator hinge fitting and bracket assembly, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by certain anomalies of the flight guidance computers. We are issuing this AD to address the unsafe condition on these products.
