98-10-07: This amendment adopts a new airworthiness directive (AD) that applies to all Alexander Schleicher Segelflugzeugbau (Alexander Schleicher) Model ASK 21 sailplanes that have certain modifications installed. This AD requires changing the sailplane flight manual s weight and balance information. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to prevent the operator from using inaccurate weight and balance information provided in the sailplane flight manual (SFM), which could lead to hazardous flight conditions.
98-10-10: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 747 and 767 series airplanes. This action requires a one-time inspection to confirm the installation of Teflon sleeves over certain electrical wires inside conduits installed in the fuel tanks; and corrective actions, if necessary. This amendment is prompted by a report of missing Teflon sleeves, which protect the wiring insulation from chafing. The actions specified in this AD are intended to prevent such chafing, which could eventually expose the electrical conductor creating the potential for arcing from the wire to the conduit, and consequent fuel tank fire/explosion.
2017-10-19: We are adopting a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) Trent 1000-A2, Trent 1000-C2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 turbofan engines. This AD requires initial and repetitive on-wing inspections of affected intermediate pressure compressor (IPC) rotor seals. This AD was prompted by a failure of the IPC rotor seal. We are [[Page 30956]] issuing this AD to correct the unsafe condition on these products.
64-12-04: 64-12-04 GENERAL DYNAMICS: Amdt. 742 Part 507 Federal Register June 5, 1964. Applies to All Models 22, 22M, 30 and 30A Aircraft. Compliance required within 1,500 hours' time in service after the effective date of this AD, unless already accomplished. Inadvertent operation of the engine air turbine starter at continuous overspeeds has occurred in flight. This caused failure of the starter with resultant damage to surrounding nacelle structure and propulsion systems. To preclude starter failures of this nature, the following modifications and airplane flight manual procedures are required: (a) Modify the Models 22, 22M, 30, and 30A starter operation warning systems to include a master warning light indication when the starter valve is in the open position in accordance with the following General Dynamics/Convair Service Bulletins or an FAA approved equivalent: (1) General Dynamics/Convair Service Bulletin 880 S.B. No. 80-5 for the Model 22. (2) General Dynamics/Convair Service Bulletin 880M S.B. No. 80-2 for the Model 22M. (3) General Dynamics/Convair Service Bulletin 990 S.B. No. 80-3 for the Models 30 and 30A. (b) As an alternative for Models 30 and 30A aircraft, relocate the existing starter operation warning lights from the flight engineer's panel assembly to the pilot's overhead control panel per General Dynamics/Convair Service Bulletin 990 S.B. No. 80-1. (c) FAA engineering approval of equivalent methods of complying with (a) shall be processed through the FAA, Aircraft Engineering Division, Western Region. (d) Revise the Emergency Procedures section of the appropriate FAA approved Airplane Flight Manual to incorporate the procedure for isolating a malfunctioning starter valve in flight as set forth in the following FAA approved General Dynamics/Convair Airplane Flight Manual revisions: (1) Revision 73 to CS 59-061 dated December 17, 1963, for Model 22-2 and Revision 74 to CS 59-019 dated December 17, 1963, for the Model 22-1. (2) Revision 34 to CS 61-008 dated December 17, 1963, for the Model 22M. (3) Revision 32 to CS 61-048 dated December 17, 1963, for the Model 30. (4) Revision 14 to CS 62-046 dated December 17, 1963, for the Model 30A. This directive effective July 6, 1964.
2005-20-31: The FAA is rescinding an existing airworthiness directive (AD) that applies to Honeywell FMS one million word (1M or 700K) data bases (9104 cycle or earlier) as installed in, but not limited to McDonnell Douglas Model MD-11 and MD-11F airplanes, Boeing Model 747-400 series airplanes, and Boeing Model 757 and 767 airplanes. That AD requires a revision to the FAA-approved Airplane Flight Manual (AFM) and installation of a placard to prohibit the use of Nondirectional Beacon (NDB) approaches for landing. That AD was prompted by an anomaly in the Honeywell FMS one million word (1M or 700K) data bases (9104 cycle or earlier). We issued that AD to prevent an airplane deviating from the published approach to the runway, which could lead to premature ground contact before reaching the runway. Since we issued that AD, we have determined that the Honeywell FMS one million word (1M or 700K) databases (9104 cycle or earlier) no longer exist on any of the affected airplanes.

98-09-27: This amendment adopts a new airworthiness directive (AD) that is applicable to Rolls-Royce, plc RB211 Trent 768 and 772 series turbofan engines. This action requires initial and repetitive visual inspections of thrust reverser hinge lugs and attachment ribs for cracks, and, if necessary, removal from service and replacement with serviceable parts. This amendment is prompted by aircraft certification testing which revealed that stresses on the thrust reverser hinge were higher than had been anticipated during engine certification. The actions specified in this AD are intended to prevent thrust reverser hinge failure, possibly resulting in liberation of the thrust reverser cowl duct from the engine nacelle, which could result in impact damage to other sections of the aircraft. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of May 21, 1998. Comments for inclusion in the Rules Docket must be received on or before July 6, 1998.
