Airworthiness Directives; Cessna Aircraft Company 150 and 152 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for Cessna Aircraft Company (Cessna) 150 and 152 series airplanes. This AD requires you to either install a placard prohibiting spins and other acrobatic maneuvers in the airplane or to replace the rudder stop, rudder stop bumper, and attachment hardware with a new rudder stop modification kit and replace the safety wire with jamnuts. This AD results from follow-on investigations of two accidents where the rudder was found in the over-travel position with the stop plate hooked over the stop bolt heads. While neither of the accident aircraft met type design, investigations revealed that aircraft in full conformity with type design can exceed the travel limits set by the rudder stops. We are issuing this AD to prevent the rudder from traveling past the normal travel limit. Operation in this non-certificated control position is unacceptable and could cause undesirable consequences, such as contact between the rudder and the elevator.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 440) 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; Pratt & Whitney Models PW2037, PW2037(M), and PW2040 Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney models PW2037, PW2037(M), and PW2040 turbofan engines with high-pressure turbine (HPT) 2nd stage hubs that have previously been exposed to Pratt & Whitney cleaning procedure SPOP 10 or SPOP 9 or equivalent procedure. This AD requires a onetime optical comparator inspection (OCI) of the blade retention slots of the affected HPT 2nd stage hubs at the next HPT overhaul after the effective date of the AD. This AD results from an uncontained release of HPT 2nd stage blades and blade retention lugs. We are issuing this AD to remove nonconforming HPT 2nd stage hubs, which could result in an uncontained release of turbine blades and blade retention lugs, and damage to the airplane.
Airworthiness Directives; Boeing Model 747-400 and 747-400D Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 747-400 and 747-400D series airplanes. This AD requires repetitive inspections to detect cracks in the floor panel attachment fastener holes of the Section 41 upper deck floor beam upper chords, and related investigative and corrective actions if necessary. This AD results from reports of cracks found in the Section 41 upper deck floor beam upper chords. We are issuing this AD to detect and correct cracks in these chords, which could become large and cause the floor beams to become severed and result in rapid decompression or reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A380-841, -842, and -861 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; Diamond Aircraft Industries GmbH Model DA 40 and DA 40 F Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above to supersede an existing AD. 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; Rolls-Royce Corporation (RRC) AE 3007A Series Turbofan Engines
This document publishes in the Federal Register an amendment adopting emergency airworthiness directive (AD) 2009-08-51 that was sent previously to all known U.S. owners and operators of RRC AE 3007A series turbofan engines. This AD requires performing an eddy current inspection (ECI) or surface wave ultrasonic test (SWUT) inspection on each affected high-pressure turbine wheel. This AD results from additional reports of cracks in the high-pressure turbine (HPT) stage 2 wheels identified from the required inspections in AD 2008-26-06. A revised risk assessment that includes these additional reports indicates we need to require a higher inspection rate. We are issuing this AD to prevent an uncontained failure of the HPT stage 2 wheel and damage to the airplane.
Airworthiness Directives; EADS-PZL “Warszawa-Okęcie” S.A. Model PZL-104 WILGA 80 Airplanes

The FAA is issuing this notice to advise the public of the cancelation of a meeting of the NextGen Mid-Term Implementation Task Force.
Airworthiness Directives; CFM International, S.A. CFM56-7B Series Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for CFM International, S.A. CFM56-7B series turbofan engines. This proposed AD would require initial and repetitive eddy current inspections (ECIs) of certain part number (P/N) low-pressure (LP) turbine rear frames. This proposed AD results from a refined life analysis by the engine manufacturer that shows the need to identify an initial and repetitive inspection threshold for inspecting certain LP turbine rear frames. We are proposing this AD to prevent failure of the LP turbine rear frame from low-cycle-fatigue cracks. Failure of the LP turbine rear frame could result in engine separation from the airplane, possibly leading to loss of control of the airplane.
Special Requirements for Private Use Transport Category Airplanes
This special federal aviation regulation (SFAR) amends the airworthiness standards for transport category airplanes by adding new cabin interior criteria for operators of private use, not for hire, not for common carriage airplanes. These standards may be used instead of the specific requirements that affect transport category airplanes operated by air carriers. These standards supplement the requirements for operation under the air traffic and general operating rules. This SFAR provides alternative criteria for transport category airplanes that are operated for private use while continuing to provide an acceptable level of safety for those operations.
Executive Committee of the Aviation Rulemaking Advisory Committee; Meeting
The FAA is issuing this notice to advise the public of a meeting of the Executive Committee of the Aviation Rulemaking Advisory Committee.
Airworthiness Directives; PILATUS AIRCRAFT LTD. Models PC-12, PC-12/45, PC-12/47 and PC-12/47E 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 (two different MCAI) describe the unsafe conditions as:
Airworthiness Directives; 328 Support Services GmbH Dornier Model 328-100 and -300 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; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires repetitive detailed and high frequency eddy current inspections to detect cracks of the backup intercostals and the upper sill of the forward airstair doorway, and applicable corrective actions. This AD also provides for an optional terminating action, which would eliminate the need for repetitive inspections. This AD results from a report indicating that cracks were found in the backup intercostals and upper sill web of the forward airstair doorway. We are issuing this AD to detect and correct fatigue cracking of the backup intercostals and upper sill web of the forward airstair doorway, which could result in a rapid loss of cabin pressure.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
We are adopting a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. For all airplanes, this AD requires repetitive overhaul of the retract actuator beam of the main landing gear (MLG). For certain airplanes, this AD requires repetitive inspections for damage of the retract actuator beam, and related investigative and corrective actions if necessary. This AD results from reports of broken retract actuator beams of the MLG and the subsequent failure of the MLG to fully retract. We are issuing this AD to detect and correct broken retract actuator beams of the MLG, which could cause damage to the beam arm, hydraulic tubing, and flight control cables. Damage to the flight control cables could result in loss of control of the airplane.
Airworthiness Directives; Boeing Model 747 Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 747 airplanes. This AD requires repetitive external surface high frequency eddy current inspections to detect cracks in the radius detail of the upper lobe doubler on both sides of the airplane, and applicable corrective action. This AD results from reports of cracks in the radius detail of the upper lobe doublers. We are issuing this AD to detect and correct cracks in the upper lobe doublers. Such cracks could result in significant degradation of the fuselage structure and reduce its ability to carry flight loads from the vertical stabilizer, which could adversely affect the controllability of the airplane.
Repair Stations; Withdrawal
The FAA is withdrawing a previously published NPRM that proposed to revise the system of ratings and require repair stations to establish a quality program. The NPRM also proposed to require each repair station to maintain a capability list, designate a chief inspector, and have permanent housing for facilities, equipment, materials, and personnel. The proposal would have specified additional instances where the FAA may deny a repair station certificate, and clarified some existing repair station regulations. We are withdrawing the NPRM because we have determined that it does not
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 190 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; BAE Systems (Operations) Limited Model BAe 146-100A and 146-200A Series 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; Airbus Model A310-203 and -222 Airplanes and Model A300 B4-620 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:
Airworthiness Directives; Boeing Model 777-200 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200 series airplanes. This proposed AD would require installing a new insulation blanket on the latch beam firewall of each thrust reverser (T/R) half. This proposed 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 proposing 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; Boeing Model 737-300 and 737-400 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 737-300 and 737-400 series airplanes. This proposed AD would require repetitive inspections to detect cracking of the aft fuselage skin, and related investigative/corrective actions if necessary. This proposed AD results from reports of cracks in the aft fuselage skin on both sides of the airplane. We are proposing this AD to detect and correct cracking in the aft fuselage skin along the longitudinal edges of the bonded skin doubler, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; BAE Systems (Operations) Limited (Jetstream) Model 4101 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. That AD currently requires operators to determine the number of flight cycles accumulated on each component of the main landing gear (MLG) and the nose landing gear (NLG), and to replace each component that reaches its life limit with a serviceable component. The existing AD also requires operators to revise the Airworthiness Limitations (AWL) section of the Instructions for Continued Airworthiness (ICA) in the aircraft maintenance manual to reflect the new life limits for structurally significant items. This new AD requires a new revision of the AWL section of the ICA to incorporate revised life limits for structurally significant items, operational and functional tests of certain systems, and instructions to retain critical ignition source prevention features during configuration changes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. We are issuing this AD to prevent failure of certain structurally significant items, including the MLG and the NLG, which could result in reduced structural integrity of the airplane; and to prevent fuel vapor ignition sources, which could result in fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on March 24, 2009 (74 FR 12247). The error resulted in publication of an incorrect AD number. This AD applies to certain Airbus Model A318, A319, A320, and A321 airplanes. This AD requires the installation of improved cockpit door latch/striker assemblies.
Modification of Class D and E Airspace; Albemarle, NC
This action modifies Class D and Class E airspace at Albemarle, NC. Controlled airspace is being expanded to contain the Final Approach Fix (FAF) for a Standard Instrument Approach Procedure (SIAP) into Stanly County Airport. This action enhances the National Airspace System by providing controlled airspace in the vicinity of Albemarle, NC.
Establishment of Class E Airspace; Clewiston, FL
This action confirms the effective date of a direct final rule that establishes Class E Airspace at Clewiston, FL needed to support new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) developed for Airglades Airport. As a result, controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain the SIAP and for Instrument Flight Rule (IFR) operations changing the operating status of the airport from Visual flight Rules (VFR) to include IFR operations concurrent with the publication of the SIAP.
Establishment of Class E Airspace; Russellville, AL
This action confirms the effective date of a direct final rule that establishes Class E Airspace at Russellville, AL needed to support new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) developed for Russellville Municipal Airport. As a result, controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain the SIAP and for Instrument Flight Rule (IFR) operations changing the operating status of the airport from Visual flight Rules (VFR) to include IFR operations concurrent with the publication of the SIAP.
Establishment of Class E Airspace; Morehead, KY
This action confirms the effective date of a direct final rule establishing Class E Airspace at Morehead, KY. Controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain the Standard Instrument Approach Procedures (SIAPs) at the airport.
Amendment to Class E Airspace; Rutland, VT
This action confirms the effective date of a direct final rule that amends the Class E Airspace at Rutland-Southern Vermont Regional (RUT); Rutland, VT to provide adequate controlled airspace for those aircraft using Instrument Approach Procedures to the airport. The action became necessary due to the decommissioning of the IRA NDB and new Standard Instrument Approach Procedures (SIAPs) being developed for Rutland-Southern Vermont Regional Airport. This rule also imparts a technical amendment to change the name of the airport from Rutland State Airport to Rutland-Southern Vermont Regional.
Airworthiness Directives; Boeing 737-600, -700, -700C, and -800 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, and -800 series airplanes. This proposed AD would require repetitive lubrications of the right and left main landing gear (MLG) forward trunnion pins. This proposed AD also would require an inspection for discrepancies of the transition radius of the MLG forward trunnion pins, and corrective actions if necessary. For certain airplanes, this proposed AD would also require repetitive detailed inspections for discrepancies (including finish damage, corrosion, pitting, and base metal scratches) of the transition radius of the left and right MLG trunnion pins, and corrective action if necessary. Replacing or overhauling the trunnion pins would terminate the actions required by this AD. This proposed AD results from a report that the protective finishes on the forward trunnion pins for the left and right MLG might have been damaged during final assembly. We are proposing this AD to prevent stress corrosion cracking of the forward trunnion pins, which could result in fracture of the pins and consequent collapse of the MLG.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 and ERJ 190 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; Pratt & Whitney (PW) JT9D-7R4 Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for PW JT9D-7R4 series turbofan engines. That AD currently requires removing certain reduced cooling flow 2nd stage high-pressure turbine (HPT) vane assemblies installed in certain 2nd stage HPT vane cluster assemblies. It also requires a visual and a fluorescent penetrant inspection (FPI) of the 2nd stage HPT air seal assembly, part number (P/N) 815097. This AD requires a visual and FPI of all P/N 2nd stage HPT air seal assemblies that were used with reduced cooling flow 2nd stage HPT vane assemblies. This AD results from PW identifying additional P/N air seal assemblies that are affected by the unsafe condition. We are issuing this AD to prevent uncontained failure of the 2nd stage HPT air seal assembly, leading to engine in-flight shutdown and damage to the airplane.
Amendment of Class E Airspace; Refugio, TX
This action amends the legal description of the Class E airspace at Refugio, TX. It removes the reference to the Rockport, TX, Class E airspace area to reflect its incorporation into the Corpus Christi, TX, Class E airspace area (74 FR 7560). All other legal descriptions for the Refugio, TX, airspace area remain the same.
Special Conditions: Model C-27J Airplane; Interaction of Systems and Structures
This action proposes special conditions for the Alenia Model C-27J airplane. This airplane has novel or unusual design features when compared to the state of technology described in the airworthiness standards for transport-category airplanes. These design features include electronic flight-control systems. These special conditions pertain to the effects of novel or unusual design features such as effects on the structural performance of the airplane. We have issued additional special conditions for other novel or unusual design features of the C-27J.
Proposed Establishment of VOR Federal Airway V-626; UT
This action proposes to establish VOR Federal Airway 626 (V- 626) located between the Myton, UT, Very High Frequency Omnidirectional Range/Tactical Air Navigation (VORTAC) and the Salt Lake City terminal Area. This route would improve aircraft flow during busy traffic periods into the Salt Lake City terminal area. This new jet route would provide a more precise means of navigation and reduce controller workload.
Airworthiness Directives; Thrush Aircraft, Inc. (Type Certificate Previously Held by Quality Aerospace, Inc. and Ayres Corporation) Model 600 S2D and S2R (S-2R) Series Airplanes
We propose to supersede Airworthiness Directive (AD) 2006-07- 15, which applies to Thrush Aircraft, Inc. Model 600 S2D and S2R (S-2R) series airplanes (type certificate previously held by Quality Aerospace, Inc. and Ayres Corporation). AD 2006-07-15 currently requires repetitive inspections of the \1/4\-inch and \5/16\-inch bolt hole areas on the wing front lower spar caps for fatigue cracking; replacement or repair any wing front lower spar cap where fatigue cracks are found; and reporting of any fatigue cracks found to the FAA. AD 2006-07-15 also puts the affected airplanes into groups for compliance time and applicability purposes. Since we issued AD 2006-07- 15, FAA analysis reveals that inspections are not detecting all existing cracks and shows the incidences of undetected cracks will increase as the airplanes age. Consequently, this proposed AD would retain the actions of AD 2006-07-15 and impose a life limit on the wing front lower spar caps that requires replacement of the wing front lower spar caps when the life limit is reached. This proposed AD would also change the requirements and applicability of the groups discussed above and remove the ultrasonic inspection method. We are proposing this AD to prevent wing front lower spar cap failure caused by undetected fatigue cracks. Such failure could result in loss of a wing in flight.
Amendment to Restricted Areas R-6402 A&B, R-6404 A, B, C & D, R-6405, R-6406 A & B, and R-6407; Utah
This action changes the using agency of Restricted Area 6402 (R-6402 A & B), Dugway Proving Ground; R-6404 A, B, C & D, Hill AFB; R- 6405, R-6406 A & B, Wendover; and R-6407, Hill AFB, Utah, from ``Commander, 6501 Range Squadron, Air Force Systems Command, Hill AFB, UT.'' to ``388th Fighter Wing Air Combat Command, Hill AFB UT.'' The FAA is taking this action in response to a request from the United States Department of Air Force to reflect an administrative change of responsibility for the restricted areas. There are no changes to the boundaries; designated altitudes; time of designation; or activities conducted within the affected restricted areas.
