Within 14 days after 4 September 2002.

3.         Within 1,000 flight cycles or 6 months after 4 September 2002, whichever occurs first.

4.         Before further flight.

                 5.        - Before further flight, if the MLG has not been inspected before in accordance with Messier-Dowty SB F100-32-104, dated 22 August 2002, or later UK CAA approved revision; or,

                 -            Before further flight, if a previous MLG inspection revealed cracks and the aircraft is operating during the so-called "fly-on" period (refer to Requirement 6); or,

                -          Within the next 50 flight cycles after 22 December 2004, if a previous inspection revealed cracks in the MLG that have subsequently been repaired in accordance with the requirements of Requirement 6; or.

                -          Within the next 50 flight cycles after 22 December 2004, if a previous inspection revealed no cracks in the MLG.

6.         As specified in the Requirement document.

7.         Within 7 calendar days after each required inspection.

            The compliance times for Requirements 1, 2, and 3 remain unchanged by this issue. This Amendment becomes effective on 22 December 2004.
            Background: The CAA-NL has received a report concerning a F100 aircraft with Messier-Dowty main landing gear where, upon braking during terminal push-back of the aircraft, the right hand MLG Main Fitting failed. Investigation revealed overload, initiated by a
            4.5 mm fatigue crack originating from one of the MLG filler and bleeder ports, which are located on the aft side of the MLG.

            Amendment 1 is issued in response to a revision of the related CAA-NL AD, which introduces detailed compliance changes while allowing some flexibility in repair times; and adds Mk. 0070 aircraft to applicability.
