The Goodyear Tire & Rubber Company, Grant of Petition for Decision of Inconsequential Noncompliance
The Goodyear Tire & Rubber Company (Goodyear) \1\ has determined that certain Goodyear commercial truck tires manufactured between April 2007 and July 2010 did not fully comply with paragraph S6.5(f) of Federal Motor Vehicle Safety Standard (FMVSS) No. 119, New Pneumatic Tires for Motor Vehicles with a GVWR of more than 4,536 Kilograms (10,000 Pounds) and Motorcycles. Goodyear has filed an appropriate report pursuant to 49 CFR part 573, Defect and Noncompliance Responsibility and Reports (dated August 12, 2010).
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A310 series airplanes. This proposed AD was prompted by a report of an electrical arc and hydraulic haze in the wheel bay of the left-hand main landing gear (MLG) possibly resulting from chafing between the hydraulic high pressure hose and electrical wiring of the green electrical motor pump (EMP). This proposed AD would require prohibiting in-flight use of the green EMPs; revising the airplane flight manual (AFM) limitations section; installing a placard in the cockpit overhead panel; doing a one-time general visual inspection for correct condition and installation of hydraulic pressure hoses, electrical conduits, feeder cables, and associated clamping devices; and corrective action if necessary. We are proposing this AD to detect and correct chafing of hydraulic pressure hoses and electrical wiring of the green EMPs, which in combination with a system failure, could cause an uncontrolled and undetected fire in the MLG bay.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
We propose to adopt a new airworthiness directive (AD) for all Turbomeca S.A. Arriel 2B and 2B1 turboshaft engines. This proposed AD was prompted by the discovery of non-conformities of certain power turbine (PT) blade fir-tree roots. This proposed AD would require removing the affected PT blades from service on or before reaching a new reduced life limit for those certain PT blades. We are proposing this AD to prevent PT blade rupture, which could result in an uncommanded in-flight engine shutdown, forced autorotation landing, or accident.
Airworthiness Directives; Rolls-Royce plc (RR) Turbofan Engines
We are revising an earlier proposed airworthiness directive (AD) for all RR RB211-Trent 553-61, 553A2-61, 556-61, 556A2-61, 556B- 61, 556B2-61, 560-61, 560A2-61, 768-60, 772-60, 772B-60, 875-17, 877- 17, 884-17, 884B-17, 892-17, 892B-17, and 895-17 turbofan engines. That NPRM proposed to supersede an existing AD that requires inspecting the intermediate-pressure (IP) compressor rotor shaft rear balance land for cracks, which could lead to engine failure. This action revises that NPRM by changing the optional terminating action for RB211-Trent 700 and RB211-Trent 800 engines to mandatory terminating action. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Airworthiness Directives; Agusta S.p.A. Helicopters
We propose to adopt a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB139 and AW139 helicopters with a certain generator control unit (GCU). This proposed AD was prompted by laboratory tests which revealed a potential fault in the overvoltage protection on a certain part-numbered GCU. This proposed AD would require replacing each affected GCU with an airworthy GCU. In addition, any affected GCU is not approved for installation on any helicopter. We are proposing this AD to prevent failure of the overvoltage protection of the GCU, degraded performance of the electrical power generation and distribution systems, a fire, and subsequent loss of control of the helicopter.
Membership in the National Parks Overflights Advisory Group Aviation Rulemaking Committee
By Federal Register notice (See 76 FR 65319; October 20, 2011) the National Park Service (NPS) and the Federal Aviation Administration (FAA) invited interested persons to apply to fill a vacant position on the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). That previous notice invited interested persons to apply to fill the vacancy representing Native American tribal concerns due to the incumbent member's completion of a three- year term appointment on April 2, 2012.

The FAA is issuing this notice to advise the public of the twenty-eighth meeting of RTCA Special Committee 206: Aeronautical Information and Meteorological Data Link Services
Release of Airport Property: Tampa International Airport, Tampa, FL
The FAA hereby provides notice of intent to release certain airport properties, approximately 3.407 acres, at the Tampa International Airport, Tampa, FL from the conditions, reservations, and restrictions as contained in federal grant assurances. The release of property will allow the Hillsborough County Aviation Authority to dispose of the property for other than aeronautical purposes. The property is located southwest corner airport property, adjacent to Highway 60. The parcel is currently designated as non-aeronautical use. The property will be released of its federal obligations to grant a perpetual utlility easement to the Tampa Electric Company (TECO) for relocation of transmission lines serving the Skyway Substation located off airport. The fair market value of the parcel has been determined by appraisal to be $695,000. Documents reflecting the Sponsor's request are available, by appointment only, for inspection at the Tampa International Airport and the FAA Airports District Office.
