                              A300-600ST aircraft, all certified models, all serial numbers.

   Reason:
                              The A310 Airworthiness Limitations Section (ALS) Part 4 and A300-600
                              ALS Part 4 have been issued to introduce the Airworthiness Limitations
                              applicable to A310, A300-600 and A300-600ST ageing aircraft systems in
                              the frame of aircraft extended Limit Of Validity (LOV). The first issue
                              (Revision 00) of these documents introduced Ageing Systems
                              Maintenance (ASM) limitations defined in accordance with a process
                              agreed between AIRBUS and the European Aviation Safety Agency
                              (EASA) by way of the equipment life extension study.
                              The Subpart 4-3(a) of the ALS Part 4 revision 01, related to the Trimmable
                              Horizontal Stabilizer Actuator, refers to maintenance tasks which satisfy
                              the intent of AD 2001-242(B). Therefore AD 2001-242(B) is cancelled.
                              The Subparts 4-2 and 4-3(a) of the A310 ALS Part 4 revision 01, related to
                              the Flap Screw Jack, refer to life limitations and maintenance tasks which
                              satisfy the intent of AD 85-033-067(B)R3. Therefore AD 85-033-067(B)R3
                              is cancelled.
                              The Subpart 4-3(b) of the A310 ALS Part 4 revision 01, related to the Flap

                              CN F-2005-174. Therefore AD F-2005-174 is cancelled.

   ATA 65
                            Identification/Replacement


   Manufacturer(s):         EUROCOPTER (Formerly EUROCOPTER FRANCE, AEROSPATIALE).

   Applicability:           SA 365 N1, AS 365 N2 and AS 365 N3 helicopters, all serial numbers, equipped
                            with an aluminium Tail Rotor Blade Pitch Control Shaft with Part Number (P/N)
                            365A33.6161.20 or 365A33.6161.21

   Reason:                  During a recent incident, the pilot of a Model AS 365 N2 helicopter noticed loss
                            of control of the Tail Rotor. A decision was made to continue the flight to the
                            nearest airport and an uneventful run-on landing was made.
                            Subsequent investigation showed that the Tail Rotor Blade Pitch Control Shaft
                            P/N 365A33.6161.21 had broken. This failure occurred in the main section of
                            shaft sliding area, which appeared to have been damaged by peening. For that
                            reason the origin of the crack, which developed under fatigue loading, could not
                            be determined. Most likely, accidental damage (e.g. shock impact) is thought to
                            have caused the initiation of a crack in the hard tungsten-carbide deposit on the
                            shaft. Damage of this kind cannot be detected through normal inspection
                            methods. This condition, if not corrected, could lead to further cases of control
                            shaft failure and consequent loss of tail rotor control
                            EUROCOPTER has developed a steel control shaft, P/N 365A33.6214.20, that is
                            less sensitive to shock-induced damage. For this reason, the present AD
                            requires replacement of the affected aluminium control shafts and the withdrawal
                            from service of all remaining spares.

The following airworthiness directive (AD) may be applicable to an aircraft which our records indicate is registered in your name. ADs are issued pursuant to Canadian Aviation

contingent upon compliance with all applicable ADs. Failure to comply with the requirements of an AD may invalidate the flight authorization of the aircraft. Alternative means of
compliance shall be applied for in accordance with CAR 605.84 and the above-referenced Standard.
