Department of Transportation April 3, 2014 – Federal Register Recent Federal Regulation Documents

Changes have been made to the AIP grant assurances to conform the list of General Federal Requirements to the correct numbering of some of the documents that recently changed, to add recent legislation, to revise Assurance 10 to conform to current statute, to clarify that Assurance 25, Airport Revenues, applies when an airport sponsor takes a grant for airport planning, and to note that Assurance 37 applies to airport concession disadvantaged business enterprises. Assurance 20 of the Non-Airport Sponsor Assurances for Non-Airport Sponsors Undertaking Noise Compatibility Program Projects is also revised to delete paragraphs which discussed land purchased for airport development. In addition, on April 24, 2013, the Secretary of Transportation signed the DOT Standard Title VI Assurances and Non-Discrimination Provisions, Order 1050.2A (Title VI Assurances). The Title VI Assurances were incorporated into the FAA Office of Civil Rights Order 1400.11, the ``Nondiscrimination in Federally-Assisted Programs at the Federal Aviation Administration Order,'' which was published on August 27, 2013. The changes to the AIP grant assurances in this Notice incorporate the Title VI Assurances.

We are superseding Airworthiness Directive (AD) 2010-23-12 for certain Airbus Model A330 and Model A340 series airplanes. AD 2010-23- 12 required inspecting to determine the part number for Thales Avionics Angle of Attack (AoA) probes, and replacing any affected probe with a serviceable probe. This new AD adds airplanes to the applicability and, for certain airplanes, requires that those affected probes be replaced. This AD was prompted by reports that the AoA sensors on certain airplanes were modified and re-identified without performing the inspection to determine the part number; therefore, the affected probes were not replaced with serviceable probes. We are issuing this AD to prevent erroneous AoA information and consequent delayed activation or non-activation of the AoA protection systems, which, in combination with flight at a high angle of attack, could result in reduced controllability of the airplane.

The Federal Aviation Administration (FAA) and the National Park Service (NPS) are inviting interested persons to apply to fill one existing opening and one upcoming opening on the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC) to represent environmental concerns. Selected members will each serve 3-year terms.

We are superseding airworthiness directive (AD) 2007-03-02 for all Rolls-Royce Deutschland (RRD) Tay 620-15, Tay 650-15, and Tay 651- 54 turbofan engines. AD 2007-03-02 required an ultrasonic inspection (UI) of low-pressure (LP) compressor fan blades for cracks on certain serial number (S/N) Tay 650-15 engines. AD 2007-03-02 also required, for all Tay 611-8, 620-15, Tay 650-15, and Tay 651-54 engines, initial and repetitive UIs of LP compressor fan blades. AD 2007-03-02 also required, for Tay 650-15 and Tay 651-54 engines, UIs of LP compressor fan blades whenever the blade set is removed from one engine and installed on a different engine. This AD requires additional inspections for the affected engines and removal of the Tay 611-8 engine from the applicability. This AD was prompted by a report of an additional engine failure due to multiple fan blade separation. We are issuing this AD to prevent failure of the LP compressor fan blade, engine failure, and damage to the airplane.

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by reports of excessive wear on the lower latch surface of the main landing gear (MLG) up-lock hook. This AD requires revising the maintenance program. We are issuing this AD to detect and correct up- lock hooks worn beyond the wear limit, which could prevent the successful extension of the MLG using the primary landing gear extension system, which in combination with an alternate extension system failure could result in the inability to extend the MLG.
