98-13-18: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319 and A321-100 series airplanes, that requires adjustment of the landing gear unlocked-stop screw; replacement of the shear pins in the reduction gear box and the landing gear pulley assembly with new or serviceable shear pins; a one-time inspection to detect discrepancies of the landing gear cut-out valve; an operational test of the uplock mechanical control system; and follow-on 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 non-extension of one or more landing gears, consequent damage to the airplane structure, and possible injury to passengers and crewmembers.
97-16-03: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that requires a one-time inspection of the main landing gear (MLG) retaining bolt to ensure that it is installed correctly, and adjustments or repairs, if necessary. This amendment is prompted by a report indicating that a disconnected retaining bolt was found in the MLG forward trunnion joint of a Model 767 series airplane. The actions specified by this AD are intended to prevent aft-acting trunnion loads from being transferred to the MLG beam, and consequent fracture and collapse of the MLG; this condition could result in the loss of control of the airplane on the ground.
98-13-29: This amendment adopts a new airworthiness directive (AD), applicable to all EMBRAER Model EMB-120 series airplanes, that requires revising the Airplane Flight Manual (AFM) to prohibit positioning the power levers below the flight idle stop. This amendment is prompted by incidents and accidents involving airplanes equipped with turboprop engines in which the ground propeller beta range was used improperly during flight. The actions specified by this AD are intended to prevent loss of airplane controllability or engine overspeed with consequent loss of engine power caused by the power levers being positioned below the flight idle stop while the airplane is in flight.
97-18-10: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100) airplanes that requires a one-time inspection of the direct current (DC) power distribution system for reliability, and correction or repair, of any fuse holders and associated electrical wiring, if necessary. This amendment is prompted by a report indicating that a loose fuse holder caused the DC power distribution system to short circuit on one of the affected airplanes, which resulted in a burnt wire between circuit breaker panel CBP-2 and junction box JB7. The actions specified by this AD are intended to prevent such short circuiting, which could result in a burnt wire, smoke entering the cockpit area, and consequent passenger injury due to smoke inhalation.
97-21-16: This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 97-21-16 that was sent previously to all known U.S. owners and operators of Dassault Model Mystere-Falcon series airplanes by individual notices. This AD requires a revision to the Limitations section of the FAA-approved Airplane Flight Manual (AFM) to include procedures to use certain values to correctly gauge the minimum allowable N1 speed of the operative engines during operation in icing conditions. This action is prompted by a report indicating that erroneous minimum anti-icing N1 thrust setting indications were displayed on the Engine Indication Electronic Display (EIED). The actions specified by this AD are intended to prevent flightcrew use of erroneous N1 thrust setting information displayed on the EIED, which could result in in-flight shutdown of engine(s).
98-19-08: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A321 series airplanes. This action requires revising the Airplane Flight Manual (AFM) to prohibit automatic landings and Category III operations on runways with a magnetic orientation of 170 degrees through 190 degrees inclusive. This amendment also provides for optional terminating action for the AFM revision. 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 prevent the use of erroneous automatic roll-out guidance generated by the flight management and guidance computer, which could result in the airplane departing the runway upon landing.
98-01-11: This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires replacement of certain electrical terminals with new electrical terminals. This amendment is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent loose electrical connections from causing an increase in electrical resistance, which could result in overheating at the electrical terminals and consequent smoke/fire in the airplane passenger cabin.
97-14-13: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Gulfstream Model G-159 (G-I) airplanes, that currently requires repetitive inspections to detect chafe wear on the upper diagonal engine mount tube, and replacement or repair, if necessary. This amendment requires the installation of chafe guards at the engine mounts, which terminates the currently required inspections. It also requires that the chafe guards then be repetitively inspected for chafe wear. This amendment is prompted by the development of a modification that will provide better protection of the subject area against future chafe wear. The actions specified by this AD are intended to prevent excessive chafe wear in the area of the upper diagonal engine mount tubes and trusses; if not detected and corrected, such wear could result in failure of the engine mount assembly and possible separation of the engine from the airplane.
98-13-26: This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace Model BAC 1-11 200 and 400 series airplanes, that requires repetitive detailed visual inspections to detect cracking in the trunnion fittings located in the nose landing gear (NLG) bay of the forward fuselage; and repair, 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 detect and correct cracking in the trunnion fittings of the NLG, which could lead to collapse of the NLG during takeoff and landing, and possible injury to the flight crew and passengers.
98-06-02: This amendment adopts a new airworthiness directive (AD), applicable to certain CASA Model C-212 series airplanes, that requires a one-time inspection to detect discrepancies of the spherical bearing of the aileron control rod, and corrective action, if necessary; and installation of an improved retainer washer in the movable joint of the aileron control rod. 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 loss of the movable joint of the aileron control rod, caused by deterioration of the hinges, which could result in reduced controllability of the airplane.
