2001-18-11: This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model 717 series airplanes. This action requires a one-time inspection of the support seal tubes of the rudder trim and load-feel actuator assembly of the rudder trim control system, located in the aft accessory compartment, for proper clearance between the actuator support seal tube and spring capsule assembly, and applicable follow-on/corrective actions. This action is necessary to detect and correct the accumulation of moisture in the rudder trim and load-feel actuator of the rudder trim control system. Such moisture could freeze and cause stiff operation, binding, or jamming of the rudder trim control system and consequent jamming of the rudder; and adversely affect directional control of an airplane.
2008-12-08: We are adopting a new airworthiness directive (AD) for certain Short Brothers Model SD3-60 airplanes. This AD requires deactivation of auxiliary fuel tank systems installed in accordance with Supplemental Type Certificate SA00404AT. This AD results from fuel tank system review requirements done in accordance with Special Federal Aviation Regulation No. 88 (SFAR 88), which identified potential unsafe conditions. We are issuing this AD to prevent 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.
2005-05-05: The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600); and Model A310 series airplanes; equipped with certain Honeywell inertial reference units (IRUs). This AD requires revising the Limitations section of the airplane flight manual to prohibit the use of CAT 2 and CAT 3 automatic landing and rollout procedures at certain airports. This AD is prompted by a report that some magnetic deviation tables in the IRU database are obsolete and contain significant differences with the real magnetic deviations. We are issuing this AD to prevent an airplane from deviating from the runway centerline, and possibly departing the runway.
63-17-06: 63-17-06 SIKORSKY: Amdt. 605 Part 507 Federal Register August 21, 1963. Applies to All Model S-62A Helicopters Utilizing Main Transmission Assembly P/N S6235-20000-3 through -10. Compliance required as indicated. (a) Input shaft helical gears, P/N S6235-20158 having 250 or more hours' time in service upon the effective date of this AD shall be inspected in accordance with Sikorsky Aircraft Service Bulletin No. 62B35-6 before further flight after the effective date of this AD. (b) Input shaft helical gears P/N S6235-20158 having less than 250 hours' time in service upon the effective date of this AD, shall be inspected in accordance with Sikorsky Aircraft Service Bulletin No. 62B35-6 prior to the accumulation of 250 hours' time in service. (c) The input shaft helical gears shall be reinspected within every 250 hours' time in service from the last inspection. (d) Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA Eastern Region, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for such operator. (Sikorsky Aircraft Service Bulletin No. 62B35-6 dated July 29, 1963, covers this same subject.) This directive effective upon publication in the Federal Register for all persons except those to whom it was made effective immediately by telegram dated August 2, 1963.
2005-05-10: The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 series airplanes. This AD requires repetitive detailed inspections for cracking of the elevator "G" weight support structure, and repairs if necessary. This AD also provides for an optional terminating action. This AD is prompted by reported cracking of the elevator "G" weight support structure. We are issuing this AD to prevent failure of the elevator "G" weight support structure with possible consequent jamming of the right-hand elevator servo tab and reduced controllability of the airplane.
95-16-04: This amendment adopts a new airworthiness directive (AD), applicable to AlliedSignal Inc. LTS101 series turboshaft and LTP101 series turboprop engines, that requires replacement of cast material axial compressor rotors with wrought material axial compressor rotors that have improved fatigue characteristics and material properties. This amendment is prompted by 36 reports of axial compressor blade failures on cast rotors. The actions specified by this AD are intended to prevent engine power loss and inflight engine shutdown.
2005-03-11: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 767 series airplanes. That AD currently requires repetitive detailed and eddy current inspections of the aft pressure bulkhead for damage and cracking, and repair if necessary. This new AD also requires one-time detailed and high frequency eddy current inspections of any "oil-can" located on the aft pressure bulkhead, and related corrective actions if necessary. An "oil-can" is an area on a pressure dome web that moves when pushed from the forward side. This AD is prompted by reports of cracking at "oil-can" boundaries on the aft pressure bulkhead. We are issuing this AD to detect and correct fatigue cracking of the aft pressure bulkhead, which could result in rapid depressurization of the airplane and possible damage or interference with the airplane control systems that penetrate the bulkhead, and consequent loss of controllability of the airplane. \n\nDATES: This AD becomes effective March 18, 2005. \n\n\tOn March 22, 2004 (69 FR 10321, March 5, 2004), the Director of the Federal Register approved the incorporation by reference of Boeing Alert Service Bulletin 767-53A0026, Revision 5, dated January 29, 2004.
2011-06-01: We are adopting a new 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: A fatal accident occurred to a CAP 10C, in which the pilot lost control of the aeroplane. The following investigation has revealed that the probable cause of the accident was the improper locking of a turnbuckle (locking clip missing) of the flight control cables, and the subsequent inadvertent release of the pitchup control cable from the turnbuckle. We are issuing this AD to require actions to correct the unsafe condition on these products.
2001-18-12: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 767-200, -300, -300F and -400ER series airplanes. This action requires repetitive inspections to find discrepancies of the wire bundles located between the P50 panel and the nose wheel well structure, and corrective actions, if necessary. This action is necessary to find and fix such discrepancies, which could result in electrical arcing, smoke, or fire in the cabin, and failure of certain systems essential to safe flight and landing of the airplane. This action is intended to address the identified unsafe condition.
2008-12-03: We are adopting a new airworthiness directive (AD) for various transport category airplanes. This AD requires deactivation of Rogerson Aircraft Corporation auxiliary fuel tanks. This AD results from fuel system reviews conducted by the manufacturer, which identified potential unsafe conditions for which the manufacturer has not provided corrective actions. We are issuing this AD to prevent 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.
