To detect and repair cracks in the nose landing gear sustaining ram, accomplish the following: (a) Within the next 500 landings after the effective date of this AD or before the accumulation of 20,500 landings, whichever occurs later, unless already accomplished within the last 1,000 landings, and thereafter at intervals not to exceed 1,500 landings from the last inspection, inspect the nose landing gear sustaining ram P/N AB44A-1399, for cracks using a permanent magnet or suitable electro-magnetic process in accordance with paragraph 2.1.1 of British Aerospace, Aircraft Group, Alert Service Bulletin 32-A-PM5070, Issue No. 3, dated March 29, 1979 (hereinafter referred to as the Service Bulletin), or an FAA-approved equivalent. (b) If cracks are found during an inspection required by paragraph (a) of this AD which exceed the limits specified in paragraph 2.1.7 of the Service Bulletin, before further flight, replace the nose landing gear sustaining ram, P/N AB44A-1399, with a serviceable part of the same part number. (c) If cracks are found during an inspection required by paragraph (a) of this AD which do not exceed the limits specified in paragraph 2.1.7 of the Service Bulletin, before further flight, either - (1) Replace the nose landing gear sustaining ram, P/N AB44A-1399, with a serviceable part of the same part number; or (2) Remove the cracks in accordance with instructions in paragraph 2.1.4 of the Service Bulletin, or an FAA-approved equivalent, and reprotect the ram in accordance with the instructions in either paragraph 2.1.5 or 2.1.6 of the Service Bulletin, or an FAA-approved equivalent.
