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.

98-11-09: This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-145 series airplanes, that requires a one-time visual inspection of the pilot valve harness tubes for bulges and cracks, cleaning the tubes, applying sealant at the tube end opening, and replacing any discrepant tubes with serviceable tubes. This amendment also requires replacement of the pilot valve harness tubes and vent valve tubes with new tubes having improved anti-corrosion protection. 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 cracking of the pilot valve harness tubes, which could allow fuel to enter the conduit and leak overboard; this condition could result in increased risk of a fuel tank explosion and fire.

98-09-03: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A310 and A300-600 series airplanes, that requires a one-time, detailed visual inspection for discrepancies of the electrical bundles in the power generation compartment, 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 chafing and consequent damage to the electrical generation wires in the 101VU panel, which could result in a loss of electrical generation channels.

(a) Before each flight after the effective date of this AD check the MGB magnetic plug for particles and check the main gear box for abnormal friction points or noise by slowly rotating the main rotor by hand.
(b) Before the first flight of each day after the effective date of this AD or within intervals of 5 hours MGB time in service after the last inspection, whichever occurs first, check the MGB oil filter for foreign metallic particles.
(c) If highly heated and laminated (black) particles appear on the magnetic plug, or if fine particles deposited on the magnetic plug are preceded or accompanied by bronze particles left in the main gear box oil filter, or if abnormal friction points or noise is detected on the main gear box, prior to further flight replace main gear box with a serviceable part of the same part number incorporating Modification AMS 07.7077, or an FAA-approved equivalent. The checks required by this AD may be performed by the pilot.
