Department of Transportation February 2016 – Federal Register Recent Federal Regulation Documents

We are superseding Airworthiness Directive (AD) 2004-20-14, for all Airbus Model A300 B4-2C, B4-103, and B4-203 airplanes; and all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes. AD 2004-20-14 required repetitive inspections to detect cracking of the splice fitting at fuselage frame (FR) 47 between stringers 24 and 26 (left- and right-hand sides), and corrective actions if necessary. This new AD reduces the inspection compliance time and repetitive inspection intervals, and adds Airbus Model A300 C4-605R Variant F airplanes to the applicability. This AD was prompted by a determination that the inspection compliance time and repetitive inspection interval must be reduced to allow timely detection of cracks in the splice fitting at fuselage FR 47. We are issuing this AD to detect and correct cracking of the splice fitting at fuselage FR 47; such cracking could result in reduced structural integrity of the airplane.

The Federal Transit Administration is updating the Uniform System of Accounts (USOA). The proposed updates are prompted by the outdated nature of the 1995 USOA. FTA is seeking public comment on these proposed changes before releasing the updated USOA and implementing the associated changes to 49 U.S.C. 5335, National Transit Database.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

In accordance with the requirements of section 3506(c)(2)(A) of the Paperwork Reduction Act of 1995, this notice announces the intention of the BTS to request the Office of Management and Budget's (OMB's) approval for an information collection related to the nation's ferry operations. The information collected will be used to produce a descriptive database of existing ferry operations. A summary report of survey findings will also be published by BTS on the BTS Web page.

As authorized by 46 U.S.C. 12121, the Secretary of Transportation, as represented by the Maritime Administration (MARAD), is authorized to grant waivers of the U.S.-build requirement of the coastwise laws under certain circumstances. A request for such a waiver has been received by MARAD. The vessel, and a brief description of the proposed service, is listed below.

The Maritime Administration is updating its inventory of U.S.- flag launch barges. Additions, changes and comments to the list are requested. Launch barge information may be found at https:// www.marad.dot.gov/ships-and-shipping/domestic-shipping/launch -barge- program/.

We propose to adopt a new airworthiness directive (AD) for certain Turbomeca S.A. Astazou XIV B and H turboshaft engines. This proposed AD was prompted by a report of a crack on the 3rd stage turbine wheel. This proposed AD would require a one-time inspection of the front surface of the 3rd stage turbine for a groove. We are proposing this AD to prevent cracks in the 3rd stage turbine wheel, failure of the engine, in-flight shutdown, and loss of control of the helicopter.

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-100-1A10 (Challenger 300) airplanes. This AD was prompted by multiple reports of a short circuit between the heater element and the metal sheath of the pitot-static probe heater. This AD requires replacement of the left and right pitot-static probes with newly redesigned left and right pitot-static probes. We are issuing this AD to prevent degradation of the heating ability of the pitot- static probe heater, resulting in erroneous airspeed indication during flight in icing conditions and consequent reduced controllability of the airplane.

We propose to supersede Airworthiness Directive (AD) 2004-23- 20 for certain Airbus Model A300 series airplanes and Model A300 B4- 601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, and C4-605R Variant F airplanes. AD 2004-23-20 currently requires, for certain airplanes, repetitive inspections for cracking around certain attachment holes, installation of new fasteners for certain airplanes, and follow-on corrective actions if necessary. AD 2004-23-20 also requires modifying certain fuselage frames, which terminates certain repetitive inspections. Since we issued AD 2004-23- 20, we received a report indicating that the material used to manufacture the upper frame feet was changed and negatively affected the fatigue life of the frame feet. This proposed AD would reduce the compliance times for the initial inspection and the inspection intervals. This proposed AD would also expand the applicability and require an additional repair on certain airplanes that have been modified. We are proposing this AD to prevent cracking of the center section of the fuselage, which could result in a ruptured frame foot and reduced structural integrity of the airplane.
