B. For Model BAC 1-11 400 series airplanes [pre-modification PM3070; Modification PM3070 with main support beams, Part No. EDO3-1001/2; or Modification PM5928]: At or prior to the accumulation of 15,000 landings, or within 1,500 landings after March 17, 1986 (which is the effective date of AD 86-04-07, Amendment 39-5235), whichever occurs later, perform an eddy current or dye penetrant inspection for cracks in the rear pintle support beam, in accordance with paragraph 2.1.1 of the accomplishment instructions of British Aerospace BAC 1-11 Alert Service Bulletin 57-A-PM5896, Issue Number 4, dated February 17, 1988.
