98-23-10: This amendment adopts a new airworthiness directive (AD) that applies to all Burkhart GROB Luft-und Raumfahrt GmbH (Grob) Model G 109B gliders. This AD requires inspecting the engine mounting frame for paint scratches and damage (abrasions, notches, or chafing); and repairing any paint scratches, and repairing or replacing any engine mounting frame that is found damaged. 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 detect and correct damage to the engine mounting frame, which could result in failure of the engine mount structure with consequent loss of the engine.
2000-15-05: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-10-10, -10F, -15, -30, -30F (KC-10A and KDC-10 military), -40, and -40F series airplanes, that requires a one-time inspection of the wiring and wire bundles of the aft main avionics rack (MAR) to determine if the wires are damaged, or riding or chafing on structure, clamps, braces, standoffs, or clips, and to detect damaged or out of alignment rubber cushion inserts of the wiring clamps; and corrective actions, if necessary. This amendment is prompted by an incident in which the automatic and manual cargo door test in the cockpit was inoperative during dispatch of the airplane, due to wiring of the MAR chafing against clamps as a result of the wire bundles being installed improperly during production of the airplane. The actions specified by this AD are intended to ensure that the wires that route from the main wire bundles to the MAR and associated brackets, clamps, braces, standoffs, and clips are installed properly. Improper installation of such wiring and structure could cause chafing of the wires/wire bundles, which could result in electrical arcing, smoke, and possible fire in the MAR.
98-13-12 R1: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737, 747, 757, 767, and 777 series airplanes. This action requires a one-time inspection to detect discrepancies of the fasteners that connect the pushrods to the rudder pedal assemblies; and corrective actions, if necessary. This amendment is prompted by reports of loose and missing fasteners due to incorrect installation. The actions specified in this AD are intended to prevent loss of rudder control, jamming of the rudder system, uncommanded movement of the rudder system, and consequent reduced controllability of the airplane, due to loose or missing fasteners that connect the pushrods to the rudder pedal assemblies.

These documents also may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Los Angeles Aircraft Certification Office, 4344 Donald Douglas Drive, Long Beach, California. \n\n\tThis amendment becomes effective August 26, 1985.
98-10-02: This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace (Jetstream) Model 4101 airplanes, that requires replacement of certain wheel tie bolts with new bolts; and placing a life limit on these wheel tie bolts. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent metal fatigue failure of the wheel tie bolts, which could result in a tire burst or loss of the main wheel/tire assembly, and consequent reduced controllability of the airplane.
99-21-20: This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Falcon 2000 series airplanes, that requires a detailed inspection for interference between the safety-lock hooks and upper cowls, and corrective action, if necessary. This amendment also requires modification of the attachment supports of the inner locking hooks; and a detailed inspection of the safety-lock hooks on the lower engine cowl for proper operation and for clearance between the outer edges of the upper and lower cowls; and corrective actions, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent unintended disengagement of the engine cowl hooks during ground maintenance, which could result in in-flight loss of an engine cowl from the airplane and possible damage to the airplane and persons or property on the ground.
98-06-35: This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA-366G1 helicopters. This action requires initial and repetitive inspections of the tail rotor blade Kevlar tie-bar (Kevlar tie-bar) for delaminations. This amendment is prompted by a report of delamination of a Kevlar tie-bar. The actions specified in this AD are intended to detect delaminations of the Kevlar tie-bar, that could result in loss of anti-torque function and subsequent loss of control of the helicopter.
98-03-17: This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace Model HS 748 series airplanes. This action requires repetitive inspections to detect discrepancies of the gust locks of the flight control system, re-rigging of the gust lock system; and corrective action, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to detect and correct failure of the flight control gust lock system, which could result in reduced controllability of the airplane.
