Airworthiness Directives; Short Brothers Model SD360. Final rule. SUMMARY: 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: There have been several occurrences of cracked elevator trim tab balance weight attachment brackets, on one occasion, the elevator trim tab mass balance weight bracket separated from the aircraft. The loss of an elevator trim tab mass balance weight bracket has the potential to cause damage to an aircraft, or cause serious injury to personnel. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective September 16, 2009.

Airworthiness Directives; Boeing Model 737-600, -700, -700C, -800, and -900. Final rule. SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. That AD currently requires replacing brackets that hold the P5 panel to the airplane structure, the standby compass bracket assembly, the generator drive and standby power module, and the air conditioning module, as applicable. The existing AD also currently requires, among other actions, inspecting for wire length and for damage of the connectors and the wire bundles, and doing applicable corrective actions if necessary. This new AD requires an additional operational test of the P5-14 panel. This AD results from a report of an electrical burning smell in the flight compartment. We are issuing this AD to prevent wire bundles from contacting the overhead dripshield panel and modules in the P5 overhead panel, which could result in electrical arcing and shorting of the electrical connector and consequent loss of several critical systems essential for safe flight; and to ensure proper operation of the passenger oxygen system. If an improperly functioning passenger oxygen system goes undetected, the passenger oxygen mask could fail to deploy and result in possible incapacitation of passengers during a depressurization event. DATES: This AD becomes effective September 22, 2009.

Airworthiness Directives; Gulfstream Model G-IV, GIV-X, and GV-SP and Model GV. Final rule; request for comments. SUMMARY: This AD requires, for certain airplanes, a one-time inspection for sealant applied to the exterior of the auxiliary power unit (APU) enclosure (firewall), and, for airplanes with the subject sealant and certain other airplanes, a revision of the airplane flight manual to prohibit operation of the APU during certain ground and flight operations. This AD results from notification from the airplane manufacturer that an improper, flammable sealant was used on the interior and exterior of the APU enclosure (firewall). We are issuing this AD to prevent this flammable sealant from igniting the exterior surfaces of the APU enclosure (firewall) under certain anomalous conditions such as an APU failure/APU compartment fire, which could result in propagation of an uncontained fire to other critical areas of the airplane. DATES: This AD is effective August 26, 2009.

Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ. Final rule. SUMMARY: 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: The airbrake upper crossbeam on an airplane failed in-flight. The crossbeam failure caused damage to the rudder control system, resulting in loss of rudder control. Loss of rudder control will cause handling difficulties particularly during take-off, approach, and landing phases in cross winds. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective September 22, 2009.

Airworthiness Directives; Airbus Model A318, A319, A320, and A321. Final rule. SUMMARY: 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: One case of elevator servo-control disconnection has been experienced on an aircraft of the A320 family. Failure occurred at the servo-control rod eye-end. Further to this finding, additional inspections have revealed cracking at the same location on a number of other servo-control rod eye ends. In one case, both actuators of the same elevator surface were affected. A dual servo-control disconnection on the same elevator could result in an uncontrolled surface, the elevator surface being neither actuated nor damped, which could lead to reduced control of the aircraft. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective September 22, 2009.

Airworthiness Directives; Honeywell International Inc. TPE331-10 and TPE331-11 Series Turboprop Engines. Final rule; request for comments. SUMMARY: This AD requires removing certain first stage turbine disks from service. This AD results from a report of an uncontained failure of a first stage turbine disk that had a metallurgical defect. We are issuing this AD to prevent uncontained failure of the first stage turbine disk and damage to the airplane. DATES: This AD becomes effective September 1, 2009. We must receive any comments on this AD by October 16, 2009.

Airworthiness Directives; Boeing Model 767. Final rule. SUMMARY: 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. DATES: This AD becomes effective October 1, 2009.

Airworthiness Directives; Saab AB, Saab Aerosystems Model SAAB 340A (SAAB/SF340A) and SAAB 340B. Final rule. SUMMARY: 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: During refueling, the ground crew detected smoke from the refuel/defuel panel illuminated placard 160VU. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective September 22, 2009.

Pilot in Command Proficiency Check and Other Changes to the Pilot and Pilot School Certification Rules. Notice of proposed rulemaking (NPRM). SUMMARY: 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.
