For the affected Model PA32R-300 aircraft, ream the existing two-piece bushings to an inside diameter of 0.624 inch to 0.625 inch, chamfer the head side of the bushing to accommodate the radius in the shank of the main gear side brace stud, and install the 5/8 inch stud, P/N 78717-02. No repetitive inspections will be required by this Airworthiness Directive when this action is accomplished on both the left and right bracket assemblies. If the bushings cannot be reamed while installed in the bracket (i.e., the bushings are loose), then install a main gear side brace bracket assembly, P/N 95643-06, P/N 95643-07, P/N 95643-08, or P/N 95643-09, as applicable.

           No repetitive inspections will be required by this Airworthiness Directive when a P/N 78717-02 (or CASA approved equivalent part number) main gear side brace stud is installed in the existing bracket assembly on both the left and right sides; or when a bracket assembly, P/N 95643-06 (or CASA approved equivalent part number), P/N 95643-07 (or CASA approved equivalent part number), P/N 95643-08 (or CASA approved equivalent part number), or P/N 95643-09 (or CASA approved equivalent part number), as applicable, is installed on both the left and right sides.

           Note 2: FAA AD 97-01-01 R1 Amdt 39-10864 refers.

                    Figure 1

           Compliance: Within the next 100 hours time in service after 4 January 1996, and thereafter at intervals not to exceed 500 hours time in service.

           The original compliance times of this Airworthiness Directive are unchanged by this amendment.

           This amendment becomes effective on 5 September 2002.

           Background: The FAA received reports of main gear side brace stud cracks, and seven associated incidents where the main landing gear collapsed. The actions specified by this Directive are intended to prevent a main gear collapse caused by main gear side brace stud cracks, which could result in loss of control of the aircraft during landing operations.

           Amendment 1 allows reaming of the existing bushings as an alternative to replacing certain bushings.

           The original issue of this Airworthiness Directive became effective on 4 January 1996.
