                     32-8, perform an initial inspection on or before 20,000 landings following each rework, and at intervals not to exceed 6000 landings thereafter.

                     (iii) Struts repaired per Part II of the Service Bulletin No. 32-8, or later
                     FAA-approved revisions, will be inspected at intervals not to exceed 6000 landings following the repair.

                  2. (a) After the effective date of this AD, on or before the accumulation of 26,000 landings on a new or modified part, or 6000 additional landings, whichever occurs later.

Background:  The intent of this AD is to detect cracks originating at the shearbolt bore in the drag strut, and prevent possible failure of the landing gear.
