modified in accordance with Gippsland Aeronautics CASA STC 83-8 (Modification GA96-01) or Kosola & Associates Inc FAA STC SA00992AT, then the requirement to carry out Requirement 2 is removed.
             However, incorporation of either STC makes the fitting subject to the inspection, maintenance and fatigue limitations in the relevant STC instructions. Further, as the Gippsland Aeronautics fitting is common to the Gippsland Aeronautics GA- 200, any Airworthiness Directives issued against the GA-200 relating to the wing fitting will be applicable to this STC.

           Any fitting found cracked is to be replaced before further flight.

           Note 4: The Authority is aware of a number of instances where the wing bolts have been overtightened upon wing reinstallation. This combined with poor tolerances between the wing lugs and the fittings can cause the fitting lugs to bend and crack. The need to comply with the appropriate wing installation instructions is emphasised.

               This Amendment becomes effective on 4 November 1999.

               Background: Two failures of a wing front spar fuselage attachment have been reported. In both cases the wing separated from the aeroplane. Since issue of this Directive, numerous cracked and corroded fittings have been reported.

               Amendment 2 extended the interval for inspection with wings removed, and required a magnetic particle inspection in lieu of the previous fluorescent penetrant inspection. The magnetic particle inspection has been demonstrated to be considerably more effective than dye penetrant methods.

               Amendment 3 clarifies the inspection requirements and addresses the amended FAA AD. Further, it includes reference to two approved STCs that relieve the Magnetic Particle Inspection.

               Amendment 2 of this Directive became effective on 4 January 1996. Amendment 1 of this Directive became effective on 25 May 1995.
               The original issue of this Directive became effective in September 1977.
