50 flight cycles or 1 week

            Greater than 40mm. Replace MLG bracket

            * As an alternative to the above repair action, the MLG bracket may be inspected at intervals not to exceed 250 flight cycles or 1 month, whichever occurs first.

            This amendment becomes effective on 22 March 2001.

            Background:  The RLD received a number of reports from F28 operators of cracks discovered in the upper girder of the main landing gear (MLG) bracket, between the stringer fitting bolts, attaching the MLG bracket and fitting to the wing upper skin. Crack surface investigation has shown that the cracking occurred due to stress corrosion.

            Amendment 1 is issued in response to a revised RLD AD which introduces repetitive inspections as a result of original inspection findings.

            The original issue of this Airworthiness Directive became effective on 15 July 1999.
