2008-06-01: 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: Bombardier Aerospace has completed a system safety review of the aircraft fuel system against fuel tank safety standards * * . [A]ssessment showed that supplemental maintenance tasks [for the fuel tank wiring harness installation, and the hydraulic system No. 3 temperature transducer, among other items] are required to prevent potential ignition sources inside the fuel system, which could result in a fuel tank explosion. * * We are issuing this AD to require actions to correct the unsafe condition on these products.
2023-21-05: The FAA is adopting a new airworthiness directive (AD) for certain Thales AVS France SAS (Thales) flight management computer navigation modules (FMC2 NAVM) installed on, but not limited to, airplanes. This AD was prompted by reports that, due to software issues, certain FMC2 NAVM navigation modules provide erroneous data to the flight management computer, compromising safe flight of the airplane. This AD requires revising the existing aircraft flight manual (AFM) for your airplane and updating the navigation database. This AD also prohibits installing a database unless certain procedures were removed. The FAA is issuing this AD to address the unsafe condition on these products.
2008-06-11: 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: Subsequent to an incident on January 2, 2006, when a Saab 340B airplane encountered icing conditions during en route climb and departed controlled flight, the NTSB (National Transportation Safety Board) has issued a number of safety recommendations. * * * * * The unsafe condition is possible stalling while operating in icing conditions, which could result in loss of control of the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
2023-21-03: The FAA is superseding Airworthiness Directive (AD) 2013-26-10 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211- 524G2-19, RB211-524G3-19, RB211-524H-36, and RB211-524H2-19 engines. AD 2013-26-10 required a one-time reduction in the cyclic life of certain high-pressure compressor (HPC) rotor stage 1 and stage 2 disks, and removal of disks that exceed the reduced cycle life. Since the FAA issued AD 2013-26-10, the manufacturer has revised the engine time limits manual (TLM), introducing new and more restrictive instructions. This AD is prompted by the manufacturer revising the engine time limits manual, introducing new and more restrictive instructions. This AD requires revisions to the airworthiness limitations section (ALS) of the operator's existing approved engine maintenance or inspection program, as applicable, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2008-05-14: The FAA adopts a new airworthiness directive (AD) for all Sierra Hotel Aero, Inc. (formerly Navion Aircraft LLC) Models Navion (L-17A), Navion A (L-17B), (L-17C), Navion B, Navion D, Navion E, Navion F, Navion G, and Navion H airplanes. This AD requires you to do a one-time inspection of the entire fuel system and repetitive functional tests of certain fuel selector valves. This AD results from reports of airplane accidents associated with leaking or improperly operating fuel selector valves. We are issuing this AD to detect and correct fuel system leaks or improperly operating fuel selector valves, which could result in the disruption of fuel flow to the engine. This failure could lead to engine power loss.
2008-05-12: The FAA is superseding an existing AD that applies to certain Airbus Model A318, A319, A320, and A321 airplanes. That AD currently requires repetitive detailed inspections of the inboard flap trunnions for any wear marks and of the sliding panels for any cracking at the long edges, and corrective actions if necessary. This new AD adds airplanes that were recently added to the type certificate data sheet and changes the inspection type. This AD results from reports of wear damage to the inboard flap trunnions after incorporation of the terminating modification. We are issuing this AD to detect and correct wear of the inboard flap trunnions, which could lead to loss of flap surface control and consequently result in the flap detaching from the airplane. A detached flap could result in damage to the tail of the airplane. DATES: This AD becomes effective April 16, 2008. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of April 16, 2008. On March 24, 2006 (71 FR 8439, February 17, 2006), the Director of the Federal Register approved the incorporation by reference of Airbus Service Bulletin A320-57-1133, excluding Appendix 01, dated July 28, 2005. On January 8, 2001 (65 FR 75603, December 4, 2000), the Director of the Federal Register approved the incorporation by reference of certain other publications listed in the AD.
2023-22-08: The FAA is superseding Airworthiness Directive (AD) 2023-04- 12, which applied to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2023-04-12 required repetitive detailed inspections of affected cargo sealing tapes and applicable corrective actions. Since the FAA issued AD 2023-04-12, additional locations have been identified that are subject to the unsafe condition. This AD retains the requirements of AD 2023-04-12 and expands the inspection area, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2008-06-05: The FAA is superseding an existing airworthiness directive (AD), which applies to all Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. That AD currently requires a revision of the airplane flight manual to include procedures for a pre-flight elevator check before each flight, repetitive inspections for cracks of the attachment lugs of the mode selector valve position transducers on the elevator servo controls, and corrective actions if necessary. This new AD retains the existing requirements, reduces the applicability of the existing AD, and adds terminating actions. For certain airplanes, this AD requires upgrading the flight control primary computers. This AD results from a report of cracks of the transducer body at its attachment lugs. We are issuing this AD to ensure proper functioning of the elevator surfaces, and to prevent cracking of the attachment lugs, which could result in partial loss of elevator function and consequent reduced controllability of the airplane.
2023-20-09: The FAA is adopting a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a determination that a new airworthiness limitation is necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to establish a new life limit for a certain main landing gear (MLG) retract actuator piston rod. The FAA is issuing this AD to address the unsafe condition on these products.
2008-05-03: We are adopting a new airworthiness directive (AD) for certain Boeing Model 747-100, -100B, -100B SUD, -200B, -200C, -200F, -300, 747SP, and 747SR series airplanes powered by General Electric (GE) CF6- 45/50 and Pratt & Whitney (P&W) JT9D-70, JT9D-3, or JT9D-7 series engines. This AD requires repetitive inspections to find cracks and broken fasteners of the rear engine mount bulkhead of the inboard and outboard nacelle struts, and repair if necessary. For certain airplanes, this AD mandates a terminating modification for certain inspections of the inboard and outboard nacelle struts. This AD results from reports of web and frame cracks and sheared attachment fasteners on the inboard and outboard nacelle struts. We are issuing this AD to detect and correct cracks and broken fasteners of the inboard and outboard nacelle struts, which could result in possible loss of the rear engine mount bulkhead load path and consequent separation of the engine from the airplane.
