Secure circuit breakers in open position. Outlets may be reactivated upon accomplishment of Boeing Service Bulletin No. 1736 or an FAA approved equivalent. \n\n\tThis directive effective upon publication in the Federal Register for all persons except those to whom it was made effective immediately by telegram dated July 6, 1962.
2009-10-09 R1: We are adopting a new airworthiness directive (AD) to revise AD 2009-10-09, which applies to Cessna Aircraft Company (Cessna) 150 and 152 series airplanes. AD 2009-10-09 requires either installing a placard prohibiting spins and other acrobatic maneuvers in the airplane or replacing the rudder stop, the rudder stop bumper, and the attachment hardware with a new rudder stop modification kit and replacing the safety wire with jamnuts. Since we issued AD 2009-10-09, we became aware of a need to clarify certain model and serial number designations, remove the duplicate requirement of replacing the safety wire with jamnuts, and clarify the conditional acceptability of using modification kit part number (P/N) SK152-25 as a terminating action to this AD. Consequently, this AD retains the actions currently required in AD 2009-10-09, corrects model designation for certain serial numbers, removes the duplicate requirement of replacing safety wire with jamnuts, and clarifies the conditional acceptability of using modification kit P/N SK152-25 as a terminating action to this AD. 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. DATES: This AD becomes effective on December 11, 2009. As of June 17, 2009 (74 FR 22429, May 13, 2009), the Director of the Federal Register approved the incorporation by reference of Cessna Aircraft Company Service Bulletin SEB01-1, dated January 22, 2001; Cessna Aircraft Company Service Kit SK152-25A, Revision A, dated February 9, 2001; and Cessna Aircraft Company Service Kit SK152-24A, Revision A, dated March 9, 2001, listed in this AD.
2008-04-19 R1: We are adopting a new airworthiness directive (AD) for the products listed above that would revise an existing AD. 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: \n\n\tSubsequent to accidents involving Fuel Tank System explosions in flight * * * and on ground, * * * Special Federal Aviation Regulation 88 (SFAR88) * * * required a safety review of the aircraft Fuel Tank System * * *. \n* * * * *\n\n\tFuel Airworthiness Limitations are items arising from a systems safety analysis that have been shown to have failure mode(s) associated with an 'unsafe condition' * * *. These are identified in Failure Conditions for which an unacceptable probability of ignition risk could exist if specific tasks and/or practices are not performed in accordance with the manufacturers' requirements. \n\nThis AD requires actions that are intended to address the unsafe condition described in the MCAI. \n\nDATES: This AD becomes effective November 18, 2009. \n\tOn April 3, 2008 (73 FR 10652, February 28, 2008), the Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD. \n\tWe must receive comments on this AD by December 18, 2009.
2008-13-15: 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: Fuel system reassessment, performed according to RBHA-E88/SFAR- 88 (Regulamento Brasileiro de Homologacao Aeronautica 88/Special Federal Aviation Regulation No. 88), requires the inclusion of new maintenance tasks in the Critical Design Configuration Control Limitations (CDCCL) and in the Fuel System Limitations (FSL), necessary to preclude ignition sources in the fuel system. * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
2009-22-02: We are adopting a new airworthiness directive (AD) for all American Champion Aircraft Corp. Models 7ECA, 7GCAA, 7GCBC, 7KCAB, 8KCAB, and 8GCBC airplanes, manufactured prior to 1989 and equipped with folding rear seat backs. This AD requires inspection of the rear seat back hinge areas for cracking and excessive elongation of the rear seat hinge bolt hole and, if cracking or excessive elongation is found, replacement of the rear seat frame. We are issuing this AD to detect and correct cracking of the rear seat back hinge area and excessive elongation of the rear seat hinge bolt hole, either of which could result in failure of the seat back. This failure could lead to a rear- seated pilot or passenger inadvertently interfering with the control stick while attempting to not roll to the rear of the airplane upon seat back failure. Consequently, this failure could result in loss of control.
2009-22-01: We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires initial and repetitive inspections of the low-pressure (LP) turbine discs stage 2 and stage 3 for corrosion, on certain serial number engines. This AD requires the same actions, but extends the applicability to additional engine serial numbers. 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: Strip results from some of the engines listed in the applicability section of this directive revealed excessively corroded low-pressure turbine disks stage 2 and stage 3. The corrosion is considered to be caused by the environment in which these engines are operated. Following a life assessment based on the strip findings it is concluded that inspections for corrosion attack are required. The action specified by this AD is intended to avoid a failure of a low-pressure turbine disk stage 2 or stage 3 due to potential corrosion problems which could result in uncontained engine failure and damage to the airplane. We are issuing this AD to detect corrosion that could cause the stage 2 or stage 3 disk of the LP turbine to fail and result in an uncontained failure of the engine.
78-24-04: 78-24-04 ISRAEL AIRCRAFT INDUSTRIES (IAI): Amendment 39-3351. Applies to Model 1121, 1121A, and 1121B airplanes, Serial Numbers through 150 except 107 and equipped with Ni-Cad battery overtemperature warning or combination overtemperature warning and indicator systems, which rely on a common single sensor per battery. Compliance required within the next 150 hours time in service after the effective date of this AD, unless already accomplished. To reduce the possibility of damage to the flexible fuel lines and potential fire in the event of an uncontrolled Ni-Cad battery thermal runaway, modify the flexible fuel line installation and after modification perform inspections and leak tests in accordance with Commodore Jet Service Bulletin No. CJ-16, dated May 31, 1977, or equivalent, approved by the Chief, Aircraft Certification Staff, FAA, Europe, Africa, and Middle East Region, c/o American Embassy, APO NY 09667. This amendment becomes effective December 20, 1978.
2009-21-09: The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce plc RB211 Trent 875-17, Trent 877-17, Trent 884- 17, Trent 892-17, Trent 892B-17, and Trent 895-17 turbofan engines with high-pressure (HP) compressor rotor rear stage 5 and 6 discs and cone shafts, part numbers (P/Ns) FK25230 and FK27899 installed. That AD currently requires removal from service of these HP compressor rotor rear stage 5 and 6 discs and cone shafts before reaching newly reduced life limits. This AD requires removing these parts at new reduced cycle limits. This AD results from Rolls-Royce plc reducing the lives of these parts and changing the life calculating method to use "Standard Duty Cycles'' with "Multiple Flight Profile Monitoring'' and "Flight Cycles'' with "Heavy Flight Profile Monitoring''. We are issuing this AD to prevent stage 5 and 6 disc crack initiation and propagation that might lead to uncontained disc failure and damage to the airplane.
2009-21-01: We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-300 and 737-400 series airplanes. This AD requires repetitive inspections to detect cracking of the aft fuselage skin, and related investigative/corrective actions if necessary. This AD results from reports of cracks in the aft fuselage skin on both sides of the airplane. We are issuing 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.
2009-19-05: We are adopting a new airworthiness directive (AD) for certain Boeing Model 747 airplanes. This AD requires repetitive inspections for cracking of the fuselage frames in section 41, and corrective actions if necessary. This AD results from reports of cracking in fuselage frames made of 2024 aluminum alloy that were installed during previous modification of the frames in section 41 and during production. We are issuing this AD to detect and correct frame cracks, which could result in cracking of the adjacent fuselage skin and consequent rapid decompression of the airplane.
