97-23-15: This amendment adopts a new airworthiness directive (AD), applicable to all Fairchild Model F-27 series airplanes, that requires revising the Airplane Flight Manual (AFM) to prohibit positioning power levers below the flight idle stop during flight, and to provide a statement of the consequences of positioning the power levers below the flight idle stop during flight. This amendment is prompted by incidents and accidents involving airplanes equipped with turboprop engines in which the propeller ground beta range was used improperly during flight. The actions specified by this AD are intended to prevent loss of airplane controllability, or engine overspeed and consequent loss of engine power caused by the power levers being positioned below the flight idle stop while the airplane is in flight.
98-06-34: This amendment adopts a new airworthiness directive (AD), applicable to all Aerospatiale Model ATR-42 and ATR-72 series airplanes, that requires revising the Airplane Flight Manual (AFM) to modify the limitation that prohibits positioning the power levers below the flight idle stop during flight, and to provide a statement of the consequences of positioning the power levers below the flight idle stop during flight. 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 and consequent loss of engine power caused by the power levers being positioned below the flight idle stop while the airplane is in flight.
97-13-03: This amendment adopts a new airworthiness directive (AD), applicable to certain Gulfstream American (Frakes Aviation) Model G-73 (Mallard) series airplanes, that requires revising the Airplane Flight Manual (AFM) to prohibit positioning the power levers below the flight idle stop, and to provide a statement of consequences of 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 propeller beta was used improperly during flight. The actions specified by this AD are intended to prevent loss of airplane controllability, or engine overspeed and consequent loss of engine power caused by the power levers being positioned below the flight idle stop while the airplane is in flight.
98-07-01: This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace BAe Model ATP airplanes, that requires inspections and tests for damage of the engine power cables, and replacement of any damaged cable with a new cable. This amendment also provides for optional modification of the engine power control cable pulley assembly. This amendment is prompted by a report of failure of an engine power cable, which could cause loss of function of the power control levers on the console. The actions specified by this AD are intended to prevent loss of function of the power control levers on the console, and subsequent loss of normal control of engine power.
97-11-03: This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A300 series airplanes, that requires inspections of the lower door surrounding structure to detect cracks and corrosion, and repair, if necessary. This amendment also requires inspections to detect cracking of the holes of the corner doublers, the fail-safe ring, and the door frames of the door structures; and repair, if necessary. In addition, this amendment will also require modification of the passenger/crew door frames, which, when accomplished, terminates certain inspections. This amendment is prompted by reports indicating that corrosion was found behind the scuff plates at exit and cargo doors, and fatigue cracks originated from certain fastener holes located in adjacent structure. The actions specified by this AD are intended to detect and correct such corrosion and fatigue cracking, which could result in reduced structural integrity of the door surroundings.
98-04-10: This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A300 and A300-600 series airplanes, that requires repetitive inspections for cracking of the lugs of hinge brackets of inner airbrakes (spoilers) No. 1 and No. 2, and corrective action, if necessary. 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 detachment of the spoilers and consequent reduced controllability of the airplane.
99-03-11: This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Beech Model 60 airplanes. This AD requires modifying the aircraft cabin heat control wiring. This AD is the result of an incident on one of the affected airplanes where the circuit control that operates the aircraft cabin heater overheated and caused the cabin heater to shut down during in-flight operation. The actions specified by this AD are intended to prevent this circuit from overheating because of the current wiring design, which could result in possible smoke/fire if the heating system continued to operate in an "over-temperature" condition. Comments for inclusion in the Rules Docket must be received on or before April 8, 1999.
98-04-34: This amendment adopts a new airworthiness directive (AD), applicable to all Mitsubishi Model YS-11 and YS-11A series airplanes, that requires revising the Airplane Flight Manual (AFM) to specify procedures that will prohibit flight in severe icing conditions (as determined by certain visual cues), limit or prohibit the use of various flight control devices while in severe icing conditions, and provide the flight crew with recognition cues for, and procedures for exiting from, severe icing conditions. This amendment is prompted by results of a review of the requirements for certification of the airplane in icing conditions, new information on the icing environment, and icing data provided currently to the flight crews. The actions specified by this AD are intended to minimize the potential hazards associated with operating the airplane in severe icing conditions by providing more clearly defined procedures and limitations associated with such conditions.
98-08-06: This amendment adopts a new airworthiness directive (AD) that applies to AERMACCHI S.p.A. S.205 series and Models S.208 and S.208A airplanes. This AD requires inspecting all flight control cables (elevator control, aileron control, rudder, flaps, nose gear steering, parking brake, safety belts, and autopilot systems) for cracks in the eye end, and replacing any control cable with any crack in the eye end. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. The actions specified by this AD are intended to prevent loss of critical airplane functions because of cracked flight control cables, which could result in loss of control of the airplane if occurring during flight.
98-05-02: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Cessna Model 750 airplanes. This action requires repetitive lubrication of the aileron feel cartridge assembly shaft. This action also requires replacement of the roll feel and centering bungee assembly with an improved assembly, which constitutes terminating action for the repetitive lubrication. This amendment is prompted by reports of partial to full jamming of the aileron control circuit during flight of the airplane. The actions specified in this AD are intended to prevent the possibility of accumulation of ice on the aileron feel cartridge assembly shaft, which could result in jamming of the aileron control circuit, and consequent reduced controllability of the airplane.
