Airworthiness Directives; Rolls-Royce Corporation (RRC) AE 3007A Series Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for RRC AE 3007A series turbofan engines. This proposed AD would require removing or performing initial and repetitive eddy current inspections (ECIs) or surface wave ultrasonic testing (SWUT) inspections on high-pressure turbine (HPT) stage 2 wheels for cracks. This proposed AD also reduces the approved life limits of certain HPT stage 2 wheels. This proposed AD results from reports of cracked HPT stage 2 wheels. We are proposing this AD to prevent uncontained failure of the HPT stage 2 wheel and damage to the airplane.
Petition for Waiver of the Terms of the Order Limiting Scheduled Operations at LaGuardia Airport
Delta Air Lines and US Airways submitted a joint waiver request from the prohibition on purchasing operating authorizations (``slots'' or ``slot interests'') at LaGuardia Airport (LGA). The carriers requested the waiver to allow them to consummate a transaction in which Delta would transfer 42 pairs of slot interests to US Airways at Ronald Reagan Washington National Airport (DCA), international route authorities to S[atilde]o Paulo and Tokyo; and terminal space at the Marine Air Terminal at LGA. US Airways would transfer 125 pairs of slot interests to Delta at LGA, and would lease an additional 15 pairs of LGA slot interests with a purchase option, together with terminal space in LGA's Terminal C. We have evaluated the proposed transaction and tentatively determined that, while the proposed transaction has a number of benefits, a grant of the waiver in its entirety would result in a substantial increase in market concentration that would harm consumers. Accordingly, while we have tentatively decided to grant Delta Air Lines' and US Airways' joint waiver request in part, we have tentatively determined that the public interest would best be served by creating new and additional competition at the airports to counterbalance the potential harm to consumers. To achieve that goal, our proposed waiver would require the divestiture of 14 pairs of slot interests at DCA and 20 pairs of slot interests at LGA to new entrant and limited incumbent carriers.
Airworthiness Directives; Turbomeca Arriel 2S1 Turboshaft Engines
We are adopting a new airworthiness directive (AD) for the products listed above. 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:

The FAA proposes to adopt a new airworthiness directive (AD) for all International Aero Engines AG (IAE) V2500-A1, V2525-D5 and V2528-D5 turbofan engines and certain serial numbers (S/Ns) of IAE V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, and V2533-A5 turbofan engines. For certain S/Ns of V2500-A1, V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, and V2533-A5 series turbofan engines, this proposed AD would require initial and repetitive on-wing ultrasonic inspections (UIs) of the high-pressure compressor (HPC) stage 3 to 8 drum for cracks. As mandatory terminating action to the repetitive inspections, this proposed AD would require removal from service of the fully silver plated nuts attaching the HPC stage 3 to 8 drum to the HPC stage 9 to 12 drum, removal of silver residue from the HPC stage 3 to 8 drum, and fluorescent penetrant inspection (FPI) of the stage 3 to 8 drum within a specified time. For all other engines, this proposed AD would require removal from service of the fully silver plated nuts attaching the HPC stage 3 to 8 drum to the HPC stage 9 to 12 drum, removal of silver residue from the HPC stage 3 to 8 drum, and FPI of the HPC stage 3 to 8 drum at the next drum piece-part exposure. This proposed AD results from reports of 39 HPC stage 3 to 8 drums found cracked since March 2009. We are proposing this AD to prevent uncontained failure of the HPC stage 3 to 8 drum, which could result in damage to the airplane.
Airworthiness Directives; The Boeing Company Model 737-700 (IGW) Series Airplanes Equipped With Auxiliary Fuel Tanks Installed in Accordance With Configuration 3 of Supplemental Type Certificate ST00936NY

The purpose and need of the ASR-9 is to enhance air traffic management for ORD to achieve the benefits of providing expanded radar coverage that would allow terminal air traffic control for additional new approach routes, as evaluated and approved in the O'Hare Modernization Environmental Impact Statement/Record of Decision.
Proposed Amendment of Jet Route J-120; Alaska
This action proposes to modify Jet Route J-120 in Alaska. The FAA is proposing this action in preparation of the eventual decommissioning of the Barter Island (BTI) Non-directional Beacon (NDB) at the village of Kaktovik, Alaska, ensuring the safe and efficient use of airspace within the National Airspace System.
Proposed Amendment of Low Altitude Area Navigation Route T-254; Houston, TX
This action proposes to modify low altitude Area Navigation (RNAV) route T-254 in the Houston, TX, terminal area by eliminating the segment between the Centex, TX, VHF Omnidirectional Range/Tactical Air Navigation (VORTAC) and the College Station, TX, VORTAC. This action would eliminate a portion of T-254 that is no longer needed; thus, enhance safety and the efficient use of the navigable airspace in the Houston, TX, terminal area.
Airworthiness Directives; McDonnell Douglas Corporation Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 Airplanes
We propose to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Corporation Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 airplanes. This proposed AD would require repetitive inspections for cracking of the lower rear spar caps of the wings, and related investigative and corrective actions if necessary. This AD would also require repetitive inspections of certain repaired areas. This proposed AD results from reports of cracking of the wing rear spar lower cap at the outboard flap and inboard drive hinge at station Xrs=164.000; the cracking is due to material fatigue from normal flap operating loads. We are proposing this AD to detect and correct such fatigue cracking, which could result in fuel leaks, damage to the wing skin or other structure, and consequent reduced structural integrity of the wing.
Airworthiness Directives; McDonnell Douglas Corporation Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC- 10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F airplanes. This proposed AD would require a one-time installation of electrical bonding jumpers for the fill valve controllers of fuel tanks. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent point-of-contact arcing or filament heating damage in the fuel tanks, which could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Gulfstream Aerospace LP Model Gulfstream 100 Airplanes, and Model Astra SPX and 1125 Westwind Astra Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This proposed 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: Incomplete closure of the MED [main entry door] may be followed by in-flight opening of the door. As a result, the MED and the adjacent fuselage structure may be damaged during opening and landing impact. Damage to the left engine by flying debris and objects may also occur.
Airworthiness Directives; The Boeing Company Model 767 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model 767 airplanes. The existing AD currently requires repetitive detailed and high frequency eddy current (HFEC) inspections of the station (STA) 1809.5 bulkhead for cracking, and corrective actions if necessary. This proposed AD would expand the inspection area to include the vertical inner chord at STA 1809.5. This proposed AD results from reported fatigue cracking in the vertical inner chord and the forward outer chord while doing the detailed inspection of the horizontal inner chord at STA 1809.5. We are proposing this AD to detect and correct fatigue cracking in the bulkhead structure at STA 1809.5 and the vertical inner chord at STA 1809.5, which could result in failure of the bulkhead structure for carrying the flight loads of the horizontal stabilizer, and consequent loss of controllability of the airplane.

Airworthiness Directives; The Boeing Company Model 767-200, -300, and -300F Series Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Model 767-200, -300, and -300F series airplanes. The existing AD currently requires repetitive detailed and eddy current inspections to detect cracks or corrosion of certain midspar fuse pins, and corrective actions if necessary. That AD also provides optional terminating action, which ends the repetitive inspections. This new AD requires reduced intervals for certain repetitive inspections. This AD results from a report of a fractured midspar fuse pin. We are issuing this AD to prevent loss of the strut and engine due to corrosion damage and cracking of both fuse pins on the same strut.
Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Model PIAGGIO P-180 Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. 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.

Airworthiness Directives; Sikorsky Aircraft Corporation Model S-92A Helicopters
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2009-23-51, which was sent previously to all known U.S. owners and operators of Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters by individual letters. This AD requires cleaning and inspecting each main gearbox (MGB) assembly mounting foot pad and rib for a crack and corrosion. If you do not find a crack, the AD requires applying a corrosion preventive compound. If you find a crack, the AD requires replacing the MGB before further flight. If you find corrosion, bubbled paint, or paint discoloration, the AD also requires you to repair the MGB before further flight. This amendment is prompted by reports of cracks in the MGB mounting foot pads and foot ribs. This condition, if not detected, could result in loss of the MGB and subsequent loss of control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron, Inc. Model 205B and 212 Helicopters
This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron, Inc. (Bell) Model 205B and 212 helicopters with certain main rotor (M/R) blade assemblies installed. This action requires inspecting the M/R blades paying particular attention to an area near the blade root for an edge void, corrosion, or a crack. This amendment is prompted by two reports of fatigue cracks on M/R blades installed on Model 212 helicopters. Both model helicopters use the same part-numbered M/R blades. The actions specified in this AD are intended to detect an edge void, corrosion, or a crack on a M/R blade, which could lead to loss of the M/R blade and subsequent loss of control of the helicopter.
Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A. Model P-180 Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. 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.

Airworthiness Directives; The Boeing Company Model 747-200C and -200F Series Airplanes
We are adopting a new airworthiness directive (AD) for all Model 747-200C and -200F series airplanes. This AD requires a high frequency eddy current (HFEC) inspection for cracks of certain fastener holes, and corrective action if necessary. This AD also requires repetitive replacements of the upper chords, straps (or angles), and radius fillers of certain upper deck floor beams, and, for any replacement that is done, detailed and open-hole HFEC inspections for cracks of the modified upper deck floor beams, and corrective actions if necessary. This AD results from a report from the manufacturer that the accomplishment of certain existing inspections, repairs, and modifications is not adequate to ensure the structural integrity of the affected 7075 series aluminum alloy upper deck floor beam upper chords on airplanes that have exceeded certain thresholds. We are issuing this AD to prevent cracking of the upper chords and straps (or angles) of the floor beams, which could lead to failure of the floor beams and consequent loss of controllability, rapid decompression, and loss of structural integrity of the airplane.
