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.
97-09-09: This amendment adopts a new airworthiness directive (AD) that applies to Raytheon Aircraft Company (formerly Beech Aircraft Corporation) Models 58P and 58PA airplanes. This action requires inspecting for cracks in the right-hand (RH) upper and lower longeron near the second RH cabin window, inspecting for missing rivets in the cabin structure (longeron) adjacent to and aft of the second RH cabin window, repairing any cracked structure or reinforcing the longeron if it is not cracked, and installing rivets, if missing. Reports of cracks in the upper and lower longeron and missing rivets that are supposed to secure the frame, splice, and longeron together prompted this action. The actions specified by this AD are intended to prevent structural cracking to the cabin caused by missing rivets, which if not corrected, could cause decompression injuries to passengers, structural failure of the fuselage, and loss of the airplane.
98-23-16: This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires the installation of certain rivets on support arm 2 of the left and right flaps. 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 fatigue cracking of the support arms of the flaps, which could result in reduced structural integrity of the airplane.
99-09-12: This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace (Jetstream) Model 4101 series airplanes, that requires repetitive inspections to detect damage of the structure associated with the engine nacelle fairing attached to the wing flaps, and repair of any damage found; drilling a new drain hole in each engine nacelle fairing; and applying a sealant to the gap between the wing flap and engine nacelle fairing. This amendment also requires correction of discrepancies, and modification of the wing flap structure, which terminates the repetitive inspections. This amendment is prompted by reports of fatigue cracks found in the structure that attaches the engine nacelle fairing to the wing flaps. The actions specified by this AD are intended to prevent such fatigue cracking, which could result in the partial or complete separation of the fairing from the wing flap, and consequent additional structural damage to the airframe and/or reduced controllability of the airplane.
98-06-14: This amendment adopts a new airworthiness directive (AD), applicable to all CASA Model CN-235 series airplanes, that requires installation of a contactor and relocation of the existing fuse in the battery circuit. 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 failure of the battery circuit due to a burned fuse, and consequent inability to restart the engine using batteries during flight
98-11-30: This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-145 series airplanes, that requires inspection of the main landing gear (MLG) bushing seats to detect cracks, and repair of the bushing hole or replacement of strut bushings with new bushings, if necessary. This amendment also requires replacement of the plain bearings of the MLG shock absorber with new bearings. 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 structural failure of the MLG due to fatigue cracking of the strut bushing seat.
