Airworthiness Directives; Eurocopter France Model AS350B, B1, B2, B3, BA, and EC130 B4 Helicopters
We propose to adopt a new airworthiness directive (AD) for the specified Eurocopter France (ECF) helicopters. This proposed AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The superseding MCAI AD states that several engine flameouts have involved failure of the 41-tooth pinion in the engine accessory gearbox. Each affected helicopter had a starter-generator manufactured by one company. Investigation revealed the torque damping system of the starter- generator was inoperative due to incorrect adjustment and caused bending stresses on the 41-tooth pinion. Failure of the pinion causes the engine fuel pump to stop operating and results in an engine flameout. The EASA AD requires a new adjustment procedure to optimize the performance of the specified starter-generator damping assembly. These proposed AD actions are intended to prevent failure of a pinion and a fuel pump, engine flameout, and subsequent loss of control of the helicopter.
Airworthiness Directives; Kaman Aerospace Corporation (Kaman) Model K-1200 Helicopters
We are adopting a new airworthiness directive (AD) for the Kaman Model K-1200 helicopters. This AD requires revising the Limitations section of the Instructions for Continued Airworthiness (ICA) by establishing a life limit of 8,000 hours time-in-service (TIS) for each main rotor blade (blade) set. Also, this AD requires removing each blade set from service if it has accumulated 8,000 or more hours time-in-service (TIS). This AD also requires replacing certain blade sets with airworthy blade sets at specified intervals based on the blade set serial number (S/N). This AD was prompted by an accident and the subsequent discovery of cracks in multiple blade spars. We are issuing this AD to prevent blade failure and subsequent loss of control of the helicopter.

Special Conditions: Eurocopter France (ECF) Model EC225LP Helicopter, Installation of a Search and Rescue (SAR) Automatic Flight Control System (AFCS)
This document proposes amended special conditions for the ECF model EC225LP helicopter. This helicopter, as modified by ECF, will have novel or unusual design features associated with installing an optional SAR AFCS. Special conditions No. 29-022-SC, published in the Federal Register on November 6, 2008 (73 FR 65968), addressed these issues. The proposed amendment revises the original final special conditions to address comments and to clarify the intent of some requirements. The applicable airworthiness standards do not contain adequate or appropriate safety standards for these design features. These special conditions contain the additional safety standards the Administrator considers necessary to show a level of safety equivalent to that established by the existing airworthiness standards.
Notification of Proposed Delegation Programs and Request for Comment

These two proposed ODA programs will provide: (1) Certification functions for rotorcraft-external load operator certificates under 14 CFR part 133 and (2) the delivery of written airman knowledge tests.
Airworthiness Directives; The Boeing Company Model 737-600, -700, -700C, -800, and -900 Series Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to the products listed above. The existing AD currently requires replacement of the power control relays in the P91 and P92 power distribution panels for the fuel boost and override pumps with new, improved relays having a ground fault interrupter (GFI) feature, or installation and maintenance of universal fault interrupters (UFIs) using a certain supplemental type certificate. Since we issued that AD, we have determined that we need to clarify which relays may be replaced by installation of UFIs. This proposed AD would continue to require the actions of the existing AD and also specify which relays may be replaced by GFIs or UFIs. We are proposing this AD to prevent pump housing burn-through due to electrical arcing, which could create a potential ignition source inside a fuel tank. This condition, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Amendment and Revocation of Class E Airspace; Vero Beach, FL
This action amends Class E surface airspace, and airspace extending upward from 700 feet above the surface, and removes Class E airspace designated as an extension to Class D surface area at Vero Beach Municipal Airport, Vero Beach, FL. The Vero Beach Non-Directional Beacon (NDB) has been decommissioned and new Standard Instrument Approach Procedures (SIAPs) have been developed for the airport. This action also updates the geographic coordinates of the St. Lucie County International Airport to aid in the navigation of our National Airspace System.
Amendment of Class E Airspace; Henderson, KY
This action amends Class E airspace at Henderson, KY. The Geneva Non-Directional Beacon (NDB) has been decommissioned and new Standard Instrument Approach Procedures (SIAPs) have been developed for Henderson City-County Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.
Establishment of Class E Airspace; Crewe, VA
This action establishes Class E Airspace at Crewe, VA, to accommodate the additional airspace needed for the Standard Instrument Approach Procedures (SIAPs) developed for Crewe Municipal Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.
Airworthiness Directives; Honeywell International LTS101 Series Turboshaft Engines and LTP101 Series Turboprop Engines
This supplemental NPRM revises an earlier proposed airworthiness directive (AD), for Honeywell International LTS101-600A series and LTS101-700D-2 turboshaft engines, and LTP101-600A-1A and LTP101-700A-1A turboprop engines with power turbine blades, part number (P/N) 4-141-084-06, installed. That proposed AD would have required removing power turbine blades, P/N 4-141-084-06 from service, using a drawdown schedule specified in that proposed AD. That proposal was prompted by reports of fatigue cracks in the airfoil of the power turbine blade. This action revises the proposed rule by expanding and clarifying the applicability to include more engine models and power turbine blade P/Ns that could have the unsafe condition, and by clarifying the applicability by specifying power turbine rotor P/Ns instead of the blade P/Ns. The actions specified by this proposed AD are intended to prevent fracture of the power turbine blade airfoil, which could result in sudden loss of engine power and prevent continued safe flight or safe landing.
Airworthiness Directives; Pratt & Whitney PW4000 Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for certain Pratt & Whitney PW4000 series turbofan engines. This AD requires initial and repetitive borescope inspections (BSI) or fluorescent penetrant inspections (FPI) for cracks in the anti-vortex tube (AVT) shelf slots on the 10th stage disk of the high-pressure compressor (HPC) drum rotor disk assembly. This AD results from 47 reports received since 2007 of HPC 10th stage disks found cracked in the AVT shelf slots during shop visit inspections. We are issuing this AD to prevent failure of the HPC 10th stage disk, uncontained engine failure, and damage to the airplane.

The Federal Aviation Administration (FAA) is issuing this Notice to advise that FAA has developed draft guidance modifying its policy requiring benefit cost analyses (BCA) for capacity projects when applying for Airport Improvement Program (AIP) grants for capacity projects at the discretion of the Secretary of Transportation. This modification proposes to raise the threshold at which BCAs are required, from $5 million to $10 million in AIP Discretionary funds. FAA invites airport sponsors and other interested parties to comment on the draft guidance. FAA will consider these comments in promulgating final BCA guidance for airport sponsors.
Noise Compatibility Program Notice, Fort Worth Alliance Airport, Fort Worth, TX
The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the city of Fort Worth, Texas under the provisions of 49 U.S.C. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR Part 150. These findings are made in recognition of the description of Federal and nonfederal responsibilities in Senate Report No. 96-52 (1980). On September 7, 2006, the FAA determined that the noise exposure maps submitted by the city of Fort Worth, Texas under Part 150 were in compliance with applicable requirements. Subsequent to this determination, the future condition noise exposure map was revised to reflect additional military operations proposed by the Department of Defense. This revision delayed acceptance of the future condition noise exposure map until May 5, 2009. On December 1, 2010, the FAA approved the Fort Worth Alliance Airport noise compatibility program. Most of the recommendations of the program were approved. No program elements relating to new or revised flight procedures for noise abatement were proposed by the city of Fort Worth.
Airworthiness Directives; Hawker Beechcraft Corporation Models B200, B200GT, B300, and B300C Airplanes
We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires fabricating and installing a placard incorporating information that limits operation when there is known or forecast icing and requires replacing a section of the pneumatic supply tube for the tail deice system with a new tube of a different material. This AD requires fabricating and installing a placard incorporating information that limits operation when there is known or forecast icing and requires replacing the entire length of the pneumatic supply tube for the tail deice system with a new tube of a different material. This AD was prompted by reports of two failures of the pneumatic supply tube for the tail deice system outside the area covered by AD 2008-07-10. We are issuing this AD to prevent collapsed pneumatic supply tubes, which could result in failure of the tail deice boots to operate. This failure could lead to loss of control in icing conditions.
Airworthiness Directives; Pacific Aerospace Limited Model FU24-954 and FU24A-954 Airplanes
We are superseding an existing 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:
Airworthiness Directives; The Boeing Company Model 777-200 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Model 777-200 series airplanes. This AD requires installing a new insulation blanket on the latch beam firewall of each thrust reverser (T/R) half. This AD results from an in-flight shutdown due to an engine fire indication; an under-cowl engine fire was extinguished after landing. The cause of the fire was uncontained failure of the starter in the engine core compartment; the fire progressed into the latch beam cavity and was fueled by oil from a damaged integrated drive generator oil line. We are issuing this AD to prevent a fire from entering the cowl or strut area, which could weaken T/R parts and result in reduced structural integrity of the T/R, possible separation of T/R parts during flight, and consequent damage to the airplane and injury to people or damage to property on the ground.
Airworthiness Directives; The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP Series Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires adding two new indicator lights on a certain panel to inform the captain and first officer of a low pressure condition in the left and right override/jettison pumps of the center wing tanks. This AD also requires replacing the left and right override/jettison switches on the M154 fuel control module on the P4 panel with improved switches and doing the associated wiring changes. This AD also requires, for certain airplanes, installation of a mounting bracket for the new indicator lights. This AD also requires a revision to the maintenance program to incorporate airworthiness limitation No. 28-AWL-22. This AD also requires a revision to the airplane flight manual to advise the flightcrew what to do in the event that the pump low pressure light on the flight engineer's panel does not illuminate when the pump is selected off. This AD was prompted by fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent uncommanded operation of the override/jettison pumps of the center wing tanks, and failure to manually shut off the override/ jettison pumps at the correct time, either of which could lead to an ignition source inside the center wing tank. This condition, in combination with flammable fuel vapors, could result in a center fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; The Boeing Company Model 777-200, -300, and -300ER Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Model 777-200, -300, and -300ER series airplanes. This AD requires installing Teflon sleeving under the clamps of certain wire bundles routed along the fuel tank boundary structure, and cap sealing certain penetrating fasteners of the main and center fuel tanks. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent electrical arcing on the fuel tank boundary structure or inside the fuel tanks, which could result in a fire or explosion.
Airworthiness Directives; Cessna Aircraft Company (Cessna) Model 172 Airplanes Modified by Supplemental Type Certificate (STC) SA01303WI
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require installing a full authority digital engine control (FADEC) backup battery, replacing the supplement pilot's operating handbook and FAA approved airplane flight manual, and replacing the FADEC backup battery every 12 calendar months. This proposed AD was prompted by an incident where an airplane experienced an in-flight engine shutdown caused by a momentary loss of electrical power to the FADEC. We are proposing this AD to prevent interruption of electrical power to the FADEC, which could result in an uncommanded engine shutdown. This failure could lead to a loss of engine power.
Airworthiness Directives; Saab AB, Saab Aerosystems Model SAAB 2000 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Airworthiness Directives; The Boeing Company Model 747 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model 747 airplanes. The existing AD currently requires repetitive inspections to detect damage of the sleeving and wire bundles of the boost pumps of the numbers 1 and 4 main fuel tanks, and of the auxiliary tank jettison pumps (if installed); replacement of any damaged sleeving with new sleeving; and repair or replacement of any damaged wires with new wires. For airplanes on which any burned wires are found, the existing AD also requires an inspection to detect damage of the conduit, and replacement of any damaged conduit with a serviceable conduit. This proposed AD would reduce the initial compliance time and repetitive inspection interval in the existing AD. This proposed AD results from fleet information indicating that the repetitive inspection interval in the existing AD is too long because excessive chafing of the sleeving continues to occur much earlier than expected between scheduled inspections. We are proposing this AD to detect and correct abrasion of the Teflon sleeving and wires in the bundles of the fuel boost pumps for the numbers 1 and 4 main fuel tanks and of the auxiliary tank jettison pumps (if installed), which could result in electrical arcing between the wires and aluminum conduit and consequent fire or explosion of the fuel tank.
Airworthiness Directives; The Boeing Company Model 767 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model 767 airplanes. The existing AD currently requires repetitive inspections to detect discrepancies of the wiring and surrounding Teflon sleeves of the fuel tank boost pumps and override/jettison pumps; replacement of the sleeves with new sleeves, for certain airplanes; and repair or replacement of the wiring and sleeves with new parts, as necessary. This proposed AD would reduce the initial compliance time and repetitive inspection interval in the existing AD. This proposed AD results from fleet information indicating that the repetitive inspection interval in the existing AD is too long because excessive chafing of the sleeving continues to occur much earlier than expected between scheduled inspections. We are proposing this AD to detect and correct chafing of the fuel pump wire insulation and consequent exposure of the electrical conductor, which could result in electrical arcing between the wires and conduit and consequent fire or explosion of the fuel tank.

These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; General Electric Company CF6 Series Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) for General Electric (GE) CF6-45/-50 series and CF6-80A series turbofan engines with certain part number (P/N) side links of the five-link forward mount assembly installed. That AD currently requires an initial and repetitive visual inspection of the side links for cracks, and stripping and reapplying the Sermetel W coating on the side link at every exposure of the side link. That AD also requires replacing the side links and pylon attachment bolts, and inspecting the fail-safe bolt and platform lug if the side links are cracked. This proposed AD would continue to require those same inspections and stripping and reapplying the Sermetel W coating, and would add two part numbers to the applicability. This proposed AD results from a review of the inspection program, which revealed that GE had omitted two affected part numbers from the applicability. We are proposing this AD to prevent failure of the side links and possible engine separation from the airplane.
Safety Management System for Certificated Airports; Extension of Comment Period
This action extends the comment period for an NPRM that was published on October 7, 2010. In that document, the FAA proposed to require each certificate holder to establish a safety management system (SMS) for its entire airfield environment (including movement and non- movement areas) to improve safety at airports hosting air carrier operations. Several associations representing airports and other aviation industry segments have requested that the FAA extend the comment period closing date to allow time to adequately analyze the NPRM and prepare comments.
