Federal Aviation Administration April 1, 2011 – Federal Register Recent Federal Regulation Documents

The Federal Aviation Administration (FAA) announces that it is reviewing a proposed Noise Compatibility Program that was submitted for Kissimmee Gateway Airport under the provisions of 49 U.S.C. 47504 et seq. (the Aviation Safety and Noise Abatement Act hereinafter referred to as ``the Act'') and 14 CFR Part 150 by the City of Kissimmee. This program was submitted subsequent to a determination by FAA that the associated Noise Exposure Maps submitted under 14 CFR Part 150 for Kissimmee Gateway Airport were in compliance with applicable requirements effective 12/11/09, and was published in the Federal Register on 12/29/09. The proposed Noise Compatibility Program will be approved or disapproved on or before September 27, 2011.

This action will modify Class E airspace at Yellowstone Airport, West Yellowstone, MT, to accommodate aircraft using Instrument Landing System (ILS) Localizer (LOC) standard instrument approach procedures at Yellowstone Airport. This will improve the safety and management of Instrument Flight Rules (IFR) operations at the airport.

We are superseding an existing airworthiness directive (AD) that applies to certain Piper Aircraft, Inc. Models PA-46-310P and PA- 46-350P airplanes that are equipped with a Lewis or Transicoil turbine inlet temperature (T.I.T.) gauge and associated probe. That AD currently requires cleaning, inspecting, and calibrating the T.I.T. system; replacing any T.I.T. system that fails the calibration test; repetitively replacing the T.I.T. probe on certain airplanes; and inserting a copy of the AD into the pilot's operating handbook (POH) for certain airplanes. This new AD retains the actions required by the previous AD (AD 99-15-04 R1), adds certain Model PA-46R-350T airplanes to the Applicability section, expands the applicability to include other T.I.T. systems, and incorporates new service information. This AD was prompted by the manufacturer revising related service information and adding an airplane model to the list of affected airplanes. We are issuing this AD to prevent improper engine operation caused by improperly calibrated T.I.T. indicators or defective T.I.T. probes, which could result in engine damage/failure with consequent loss of control of the airplane.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires installing new in-line fuses for the fuel level float switch and new in-line fuses for the pressure switch, as applicable, and changing the wiring. The proposed actions would affect the left and right wing forward spars, center wing forward spar, forward auxiliary fuel tank, and aft auxiliary fuel tank, as applicable. This AD was prompted by fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
