This AD requires inspecting the wings for internal and external damage, repairing any damage found, installing an operational limitation placard in the cockpit, adding limitations to the flight manual supplement, and reporting the results of the inspection to the FAA if damage is found. This AD was prompted by a wing overload failure and by reports of cracks in the upper wing skins on certain Cessna airplanes that are or have ever been modified by Aviation Enterprises Supplemental Type Certificate (STC) SA02055AT, SA02056AT, SA02307AT, or SA02308AT. We are issuing this AD to detect and correct damage in the wings and to prevent overload failure of the wing due to the installation of the STCs. Damage in the wing or overload failure of the wing could result in structural failure of the wing, which could result in loss of control.
Airworthiness Directives; Rolls-Royce plc (RR) RB211-524 Series Turbofan Engines
This action revises an earlier proposed airworthiness directive (AD), applicable to certain RR RB211-524 series turbofan engines. That proposal would have required initial and repetitive borescope inspections of the head section and meterpanel assembly of the combustion liner, and replacement if necessary with serviceable parts. That proposal was prompted by an inquiry submitted by an operator, which resulted in RR performing a complete review of the affected front combustion liner part numbers (P/Ns). This action revises the proposed rule by clarifying the applicability paragraph (c) of the proposed AD. We are proposing this AD to prevent deterioration of the engine combustion liner, which can result in combustion liner breakup, case burn-through, engine fire, and damage to the airplane.
Proposed Establishment of Class E Airspace; Panguitch, UT
This supplemental notice of proposed rulemaking would expand controlled Class E airspace to include a portion extending upward from 1,200 feet above the surface at Panguitch Municipal Airport, Panguitch, UT. In an NPRM published in the Federal Register June 28, 2010, the FAA proposed to establish controlled airspace from 700 feet above the surface. The FAA has reassessed the proposal to include Class E airspace 700 feet and 1,200 feet above the surface to further the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Establishment of Class E Airspace; Kalaupapa, HI
This action will establish Class E airspace at Kalaupapa, HI, to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) at Kalaupapa Airport. This will improve the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Revocation of Class C Airspace, Establishment of Class D Airspace, and Modification of Class E Airspace; Columbus, GA
This action removes the Columbus, GA, Class C airspace area; establishes Class D airspace to replace the Class C airspace; and amends the existing Class E surface area and 700 foot Class E airspace at Columbus, GA. The FAA is taking this action because Columbus Metropolitan Airport no longer meets the criteria required to qualify for a Class C airspace designation. Reconfiguring the airspace facilitates more efficient use of airspace in the Columbus, GA area. A minor correction to the geographic coordinates for Lawson Army Airfield (AAF) also will be made.
Amendment of Class D and Class E Airspace; Klamath Falls, OR
This action will amend Class D and Class E airspace at Klamath Falls, OR. Decommissioning of the Merrill Non-Directional Radio Beacon (NDB) at Klamath Falls Airport has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also will adjust the geographic coordinates of the airport and a navigation aid, and will change the name of the airport.

Request for Public Comment, Morgantown Municipal Airport, Morgantown, WV
The Federal Aviation Administration is requesting public comment on the proposed release of 46.53 acres of land currently owned by the City of Morgantown, Sponsor for the Morgantown Municipal Airport, Morgantown, West Virginia. The parcel is located within the Sixth Ward District of the City of Morgantown, Morgantown, West Virginia. The site is a 47.00 acre portion of the larger Morgantown Municipal Airport property. The land is currently being used as a cross wind runway. It has been determined that this runway is no longer needed for safety or capacity. The property is not a vital part of, or necessary for the Sponsor's operation and development of the Morgantown Airport. Once released, the land will change to a non-aeronautical use and will be transferred to the West Virginia Army National Guard (``AR- WVARNG''). Thereafter, AR-WVARNG will construct or cause the construction of and operate a West Virginia Army National Guard Readiness Center on the property. The development of this property will also bring the construction of a roadway and utilities that will be needed for subsequent development of aviation facilities on a part of the airport that is now remote and without utilities or access. The airport land being released is not needed for airport development as shown on the Airport Layout Plan. Fair Market Value has been determined based upon an appraisal of the Property.

This will improve the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Airworthiness Directives; Learjet Inc. Model 45 Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires replacing aluminum fire extinguisher discharge tubes with new, improved tubes; checking the fire extinguisher container for certain serial numbers; replacing fire extinguisher containers that have affected serial numbers; inspecting the pressure indicator on certain fire extinguisher containers for discrepancies; and performing corrective action if necessary. This AD was prompted by a report of accidental discharge of a fire extinguisher container and damage to an aluminum discharge tube. Investigation revealed that following the discharge an inaccurate pressure indication, due to the indicator dial being incorrectly staked, showed that the container was fully charged. We are issuing this AD to prevent inaccurate pressure readings and subsequent damage to the discharge tubes during operation, which could result in failure of the fire extinguisher system and an uncontained fire in an emergency situation.
Airworthiness Directives; BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146 and Avro 146-RJ Airplanes
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:
Airworthiness Directives; Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes

Airworthiness Directives; Fokker Services B.V. Model F.28 Mark 0070 and 0100 Airplanes
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: * * * * * Recently, a brake fire was reported which was caused by a ruptured brake piston. The fire was quickly extinguished but caused damage to the paint and hydraulic/electrical harness and its components. Detailed investigation showed that a hydraulic lock must have been present close to the affected brake creating enough internal pressure to rupture the piston. The most probable scenario for the hydraulic lock is a loosened (not necessarily disconnected) brake QD [quick-disconnect] coupling. Further investigation of the service experience files at Fokker Services showed that more brake fires have occurred on aeroplanes in a pre-mod SBF100-32-127 configuration. * * * * * The unsafe condition is loss of braking capability and possible brake fires, which could reduce the ability of the flightcrew to safely land the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
Airworthiness Directives; McDonnell Douglas Corporation Model DC-10-10, DC-10-10F, DC-10-30, DC-10-30F (KDC-10), DC-10-40, and DC-10-40F Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires installing a support bracket and coupler on the left and right wing-to-fuselage transition, and metallic overbraid on the left and right leading edge wire assembly. This AD was prompted by fuel system reviews conducted by the manufacturer, as well as reports that the fuel quantity system was affected by lightning-induced transients. We are issuing this AD to prevent lightning-induced transients to the fuel quantity indication system, which could cause voltage levels to go beyond original design levels between fuel tank probes and structure, and become a potential ignition source at the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; McDonnell Douglas Corporation Model MD-90-30 Airplanes
We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires modifying the auxiliary hydraulic power system (including doing all applicable related investigative and corrective actions). This new AD requires these same actions, using corrected service information. This AD was prompted by fuel system reviews conducted by the manufacturer, as well as reports of electrically shorted wires in the right wheel well and evidence of arcing on the auxiliary hydraulic pump power cables, which are routed within the tire burst area. We are issuing this AD to prevent electrically shorted wires or arcing at the auxiliary hydraulic pump power cables, which could result in a fire in the wheel well. We are also issuing this AD to reduce the potential of an ignition source adjacent to the fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
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. The MCAI describes the unsafe condition as:
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-500 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. The MCAI describes the unsafe condition as:
Airworthiness Directives; Eurocopter France (Eurocopter) Model AS350B, BA, B1, B2, B3, D, AS355E, F, F1, F2, and N Helicopters
We are adopting a new airworthiness directive (AD) for the specified Eurocopter model helicopters. This 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 MCAI AD states that the AD is issued following a report of a crack discovered in the area of the center cross-member at station X 2325, at the attachment point of the yaw channel ball-type control sheath stop, of a Model AS355N helicopter fitted with the collective-to-yaw control coupling. Investigations revealed that the helicopter did not have the structural doublers, which are combined with the collective-to-yaw control coupling installation. Repetitive loads on the non-modified cross- member may cause it to crack. A crack can reduce the yaw control travel. This AD requires actions that are intended to prevent reduced yaw control and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France (ECF) Model AS350B3 and EC130 B4 Helicopters
This amendment adopts a new airworthiness directive (AD) for the Eurocopter France Model AS350B3 and EC130 B4 helicopters. This amendment is prompted by 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 MCAI AD states that a dormant failure of one of the two contactors 53Ka or 53Kb can occur following certain modifications. Failure of a contactor can prevent switching from ``IDLE'' mode to ``FLIGHT'' mode during autorotation training making it impossible to execute a power recovery and compelling the pilot to continue the autorotation to the ground. This condition, if not corrected, can lead to an unintended touchdown to the ground during a practice autorotation at a flight-idle power setting, damage to the helicopter, and injury to the occupants.
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.
