Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 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; McDonnell Douglas 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, and MD-10-30F Airplanes
We are revising an earlier proposed airworthiness directive (AD) for certain McDonnell Douglas 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, and MD-10-30F airplanes. That action (the first supplemental NPRM) would have superseded an existing AD that currently requires installing or replacing with improved parts, as applicable, the bonding straps between the metallic frame of the fillet and the wing leading edge ribs, on both the left and right sides of the airplane. The first supplemental NPRM proposed to add a requirement to reposition or replace two bonding straps for certain airplanes. This action resulted from fuel system reviews conducted by the manufacturer. This second supplemental NPRM would add, for certain airplanes, a bonding- resistance check and an inspection to determine correct installation of certain bonding straps, and applicable corrective actions. We are proposing this second supplemental NPRM to reduce the potential of ignition sources inside fuel tanks in the event of a severe lightning strike, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Scheibe-Flugzeugbau GmbH Models Bergfalke-III, Bergfalke-II/55, SF 25C, and SF-26A Standard Gliders
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:
Aviation Rulemaking Advisory Committee Meeting on Transport Airplane and Engine Issues
This notice announces a public meeting of the FAA's Aviation Rulemaking Advisory Committee (ARAC) to discuss transport airplane and engine (TAE) issues.
Pilot in Command Proficiency Check and Other Changes to the Pilot and Pilot School Certification Rules
The FAA is proposing several changes to our pilot, flight instructor, and pilot school certification rules. The proposals include requiring pilot-in-command (PIC) proficiency checks for pilots who act as PIC of single piloted, turbojet-powered airplanes; allowing pilot applicants to apply for a private pilot certificate and an instrument rating concurrently; and making allowance in the rule to provide for the issuance of standard U.S. pilot certificates on the basis of an international licensing agreement between the FAA and a foreign civil aviation authority. The FAA has recently entered into such an agreement with the civil aviation authority of Canada. The FAA is also proposing to allow pilot schools to use Internet-based training programs without requiring schools to have a physical ground training facility. The FAA is proposing to allow pilot schools and provisional pilot schools to apply for a combined private pilot certification and instrument rating course. The FAA is also proposing to revise the definition of ``complex airplane.'' Because of changing technology in aviation, the results of successful research, and an international agreement, the FAA has determined these proposed changes to the pilot, flight instructor, and pilot school certification rules are necessary to ensure pilots are adequately trained and qualified to operate safely in the National Airspace System. The FAA has determined these proposals are needed to respond to changes in the aviation industry and to further reduce unnecessary regulatory burdens.
Airworthiness Directives; Hawker Beechcraft Corporation Models 1900, 1900C, and 1900D Airplanes
We are revising an earlier proposed airworthiness directive (AD) that applies to certain Hawker Beechcraft Corporation Models 1900, 1900C, and 1900D airplanes. The earlier NPRM would have required a one- time visual inspection and repetitive ultrasonic inspections of the left and right main landing gear (MLG) actuators for leaking and/or cracks with replacement of the actuator if leaking and/or cracks are found. The earlier NPRM resulted from reports of leaking and cracked actuators. This proposed AD would require the same actions as the earlier NPRM. Since the earlier NPRM, we have identified a MLG overhauled actuator part number and a MLG actuator approved by parts manufacturer approval (PMA) by identicality. We propose to expand the applicability to include airplanes equipped with these additional part numbers. Because this imposes an additional burden over that proposed in the earlier NPRM, we are reopening the comment period to allow the public the chance to comment on these additional MLG actuators.
Special Conditions: Bombardier Inc. Model CL-600-2B19, -2C10, -2D15 and -2D24 Airplanes; Passenger Seats With Non-Traditional, Large, Non-Metallic Panels
These special conditions are issued for Bombardier Inc. model CL-600-2B19, -2C10, -2D15 and -2D24 airplanes. These airplanes will have a novel or unusual design feature(s) associated with seats that include non-traditional, large, non-metallic panels that would affect survivability during a post-crash fire event. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These 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.
Special Conditions: Rosemount Aerospace Inc. Modification to Airbus Model A330-200 and A330-300 Airplanes: Lithium-Battery Systems
These special conditions are issued for the Airbus Model A330- 200 and A330-300 airplanes. This airplane, as modified by Rosemount Aerospace, will have a novel or unusual design feature associated with lithium batteries. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These 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; Hawker Beechcraft Corporation Models 58, 58A, 58P, 58PA, 58TC, 58TCA, 95-B55, 95-B55A, A36, A36TC, B36TC, E55, E55A, F33A, and V35B Airplanes
We propose to supersede Airworthiness Directive (AD) 91-18-19, which applies to certain Hawker Beechcraft Corporation (Hawker) (Type Certificate Numbers 3A15, 3A16, and A23CE formerly held by Raytheon Aircraft Company; formerly held by Beech Aircraft Corporation) Models 58, 58A, 58P, 58PA, 58TC, 58TCA, 95-B55, 95-B55A, A36, A36TC, B36TC, E55, E55A, F33A, and V35B airplanes. AD 91-18-19 currently requires you to do a one-time inspection of the pilot and copilot shoulder harnesses for an incorrect washer and replace any incorrect washer with the correct washer. Since we issued AD 91-18-19, we have found that the applicability of AD 91-18-19 was incorrectly stated when the Model A36TC airplane was omitted from the Applicability section. Consequently, this proposed AD would retain the actions and the serial number (SN) applicability of AD 91-18-19 and realign the SN applicability for Models A36TC and B36TC airplanes. We are proposing this AD to detect and correct an incorrect washer installed in the pilot and copilot shoulder harnesses. This failure could result in a malfunctioning shoulder harness. Such a failure could lead to occupant injury.
Airworthiness Directives; Twin Commander Aircraft Corporation Models 690, 690A, and 690B Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Twin Commander Aircraft Corporation Models 690, 690A, and 690B airplanes. This proposed AD would require you to inspect between the surface of the left-hand (LH) and right-hand (RH) upper wing skins and the engine mount beam support straps for any signs of corrosion, replace the upper steel straps with parts of improved design, and modify both wings. This proposed AD results from reports that corrosion was found between the mating surfaces of the wing upper skin surface and the engine mount beam support straps. We are proposing this AD to detect and correct corrosion on the engine mount beam support straps and the upper wing skins, which could result in failure of the engine mount beam support straps. This failure could lead to loss of the engine and possible loss of control of the airplane.
Agency Information Collection Activity Seeking OMB Approval
The FAA invites public comments about our intention to request the Office of Management and Budget's (OMB) revision of a current information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on June 8, 2009, vol. 74, no. 108, page 27233-27234. Runway incursions are a risk to the public traveling in aircraft. Feedback from these surveys is used in the prevention of runway collisions and in the medication of the severity and frequency of runway incursions.
Special Conditions: Alenia Aeronautica Model C-27J Airplane; Interaction of Systems and Structures
These special conditions are issued for the Alenia Model C-27J airplane. This airplane will have novel or unusual design features when compared to the state of technology described in the airworthiness standards for transport-category airplanes. These special conditions pertain to the effects of novel or unusual design features such as effects on the structural performance of the airplane.
Westfield-Barnes Airport, Westfield MA; FAA Approval of Noise Compatibility Program
The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the Westfield Airport Commission under the provisions of Title I of the Aviation Safety and Noise Abatement Act of 1979 (Pub. L. 96-193) and 14 CFR part 150. These findings are made in recognition of the description of federal and non-federal responsibilities in Senate Report No. 96-52 (1980). On August 3, 2009, the Airports Division Manager approved the Westfield-Barnes Airport noise compatibility program. All of the proposed program elements were approved.
Proposed Establishment of Class E Airspace; Elim, AK
This action proposes to establish Class E airspace at the Elim Airport at Elim, AK. Two Standard Instrument Approach Procedures (SIAPs) are being developed for the Elim Airport at Elim, AK. Additionally, one textual Obstacle Departure Procedure (ODP) and a Standard Instrument Departure Procedure (SID) are being developed. Adoption of this proposal would result in establishing Class E airspace upward from 700 feet (ft.) and 1,200 ft. above the surface at the Elim Airport at Elim, AK.
Special Conditions: Cessna Aircraft Company, Model 525C (CJ4); Lithium Ion Battery Installation
These special conditions are issued for the Cessna Aircraft Company, model 525C (CJ4) airplane. This airplane will have a novel or unusual design feature(s) associated with the installation of lithium ion (Li-ion) batteries. Cessna Aircraft Company proposes to use a lithium-ion main battery on the new model 525C (CJ4) commuter category airplane for main battery applications, and is also considering the use of this technology in several other auxiliary battery applications in this airplane. This type of battery possesses certain failure, operational characteristics, and maintenance requirements that differ significantly from that of the nickel cadmium and lead acid rechargeable batteries currently approved in other normal, utility, acrobatic, and commuter category airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These 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; Learjet Model 45 Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Learjet Model 45 airplanes. This proposed AD would require inspecting the baggage bay door fire barrier seal for inconel mesh in the fire barrier seal material; for certain airplanes, inspecting the fiberglass doublers for presence of red Room Temperature Vulcanizing (RTV) sealant; and doing related investigative and corrective actions if necessary. This proposed AD results from reports of incorrect external baggage door seal material and door seal sealant as well as incorrect sealant on interior baggage panels used during manufacture of the airplane. We are proposing this AD to prevent the use of door seals and sealant that do not meet flammability requirements, which could result in an uncontrollable and undetected fire within the baggage compartment.
Airworthiness Directives; Construcciones Aeronauticas, S.A. (CASA), Model CN-235, CN-235-100, CN-235-200, and CN-235-300 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 747-100, -100B, -100B SUD, -200B, and -300 Series Airplanes; and Model 747SP and 747SR Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747 series airplanes. That AD currently requires repetitive inspections to detect cracks in various areas of the fuselage internal structure, and related investigative/corrective actions if necessary. This new AD requires additional repetitive inspections for cracking of certain fuselage structure, and related investigative/corrective actions if necessary. This AD results from fatigue tests and analysis by Boeing that identified areas of the fuselage where fatigue cracks can occur. We are issuing this AD to prevent the loss of the structural integrity of the fuselage, which could result in rapid depressurization of the airplane.
Airworthiness Directives; Fokker Model F.27 Mark 050 and F.28 Mark 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.

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; Air Tractor, Inc. Models AT-802 and AT-802A Airplanes
We are adopting a new airworthiness directive (AD) for certain Air Tractor, Inc. Models AT-802 and AT-802A airplanes. This AD requires installing a rudder-aileron interconnect cable system shield kit and securing any items stowed in the baggage compartment, using tie downs and/or a cargo net until the cable shield kit is installed. We are issuing this AD to prevent jamming of the rudder-aileron interconnect cables by unsecured items in the baggage compartment, which could result in failure of the rudder-aileron interconnect cable system. This failure could lead to loss of control.
Airworthiness Directives; CFM International, S.A. CFM56-5B1/P; -5B2/P; -5B3/P; -5B3/P1; -5B4/P; -5B4/P1; -5B5/P; -5B6/P; -5B7/P; -5B8/P; -5B9/P; -5B1/3; -5B2/3; -5B3/3; -5B4/3; -5B5/3; -5B6/3; -5B7/3; -5B8/3; -5B9/3; -5B3/3B1; and -5B4/3B1 Turbofan Engines

CFM56-5B1/P; -5B2/P; -5B3/P; -5B3/P1; -5B4/P; -5B4/ P1; -5B5/P; -5B6/P; -5B7/P; -5B8/P; -5B9/P; -5B1/3; -5B2/3; -5B3/3; - 5B4/3; -5B5/3; -5B6/3; -5B7/3; -5B8/3; -5B9/3; -5B3/3B1; and -5B4/3B1 turbofan engines. This AD requires initial and repetitive eddy current inspections (ECIs) of certain part number (P/N) low-pressure (LP) turbine rear frames. This AD results from a refined lifing analysis by the engine manufacturer that shows the need to identify initial and repetitive inspection thresholds for inspecting certain LP turbine rear frames. We are issuing this AD to detect low-cycle-fatigue cracks in the LP turbine rear frame, which could result in an engine separating from the airplane, causing damage to, and possibly leading to loss of control of the airplane.
Airworthiness Directives; Boeing Model 767 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767 airplanes. This AD requires sealing certain fasteners and stiffeners in the fuel tank, changing certain wire bundle clamp configurations on the fuel tank walls, inspecting certain fasteners in the fuel tanks and to determine the method of attachment of the vortex generators, and corrective action if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent possible ignition sources in the auxiliary fuel tank, main fuel tanks, and surge tanks caused by a wiring short or lightning strike, which could result in fuel tank explosions and consequent loss of the airplane.

Establishment of Class D Airspace and Amendment of Class E Airspace; North Bend, OR
This action will establish Class D airspace and amend Class E airspace at Southwest Oregon Regional Airport, North Bend, OR. The establishment of an air traffic control tower has made this action necessary for the safety and management of aircraft within this airspace. This action will also update the name of the airport from North Bend Municipal Airport, North Bend, OR. This action will also make a minor correction to the geographic coordinates of the North Bend VORTAC and the Emire LOM/NDB.
Modification of Class E Airspace; Lake Havasu, AZ
This action will modify Class E airspace at Lake Havasu, AZ. Additional controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Lake Havasu City Airport, Lake Havasu, AZ. This will improve the safety of Instrument Flight Rules (IFR) aircraft executing the new RNAV GPS SIAP at Lake Havasu City Airport, Lake Havasu, AZ. This also makes a minor change in the airport description. It changes the 2.2-mile radius of Chemehuevi Valley Airport to a 2.3-mile radius.
Airworthiness Directives; Boeing Model 747 Airplanes
We propose to adopt a new airworthiness directive (AD) for all Boeing Model 747 airplanes. This proposed AD would require one-time detailed and high frequency eddy current inspections for cracks in the wing and horizontal stabilizer side-of-body joints and the fuselage skin circumferential splices, and repair if necessary. This proposed AD would also require, for certain airplanes, repetitive detailed inspections for cracks of the fuselage skin circumferential splices, and repair if necessary. This proposed AD results from Boeing analysis indicating that the wing and horizontal stabilizer side-of-body joints, and the fuselage skin circumferential splices are susceptible to fatigue cracking due to high cyclic loads on the airplane. We are proposing this AD to detect and correct fatigue cracking at multiple adjacent locations in the subject areas, which could connect to form large cracks and result in reduced structural integrity leading to rapid decompression and consequent loss of control of the airplane.
Airworthiness Directives; Airbus Model A310 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; General Electric Company (GE) CF34-8E Series Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) for GE CF34-8E series turbofan engines with certain part number (P/N) full authority digital electronic controls (FADECs) installed. That AD currently requires removing certain P/N FADECs. This proposed superseding AD would require removal of 12 more P/Ns of FADECs. This proposed AD results from 20 additional reports received of loss of thrust control events since AD 2008-16-01 was issued. We are proposing this AD to prevent loss of thrust control of the airplane.

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: It was reported that after commanding the landing gear lever to down the three green landing gear positioning indication was displayed followed by the LG/LEVER DISAGREE EICAS [engine indicating and crew alerting system] message. The crew decided to continue the approach and landing procedure. As soon as the crew identified that the landing gear was not extended properly, a go-around procedure was successfully performed. During maneuver, the airplane settled momentarily onto the flaps and belly.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 Airplanes; and Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP 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: It has been found the occurrence of corrosion on the Auxiliary Power Unit (APU) mounting rods that could cause the APU rod to break, affecting the APU support structure integrity.

The MCAI describes the unsafe condition as: It has been found the occurrence of corrosion on the Auxiliary Power Unit (APU) mounting rods that could cause the APU rod to break, affecting the APU support structure integrity.
Airworthiness Directives; McDonnell Douglas Model MD-11 and MD-11F Airplanes
We propose to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model MD-11 and MD-11F airplanes. This proposed AD would require a one-time inspection to determine if wires touch the upper surface of the center upper auxiliary fuel tank and marking the location, if necessary; a one-time inspection of all wire bundles above the center upper auxiliary fuel tank for splices and damage; a one-time inspection for damage to the fuel vapor barrier seal and upper surface of the center upper auxiliary fuel tank; and corrective actions, if necessary. This proposed AD would also require installation of nonmetallic barrier/shield sleeving, new clamps, new attaching hardware, and a new extruded channel. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
