Compliance required within the next 450 hours' time in service after the effective date of this AD, unless already accomplished. In order to correct for the presence of any improperly heat-treated main landing gear actuator beam terminal attach bolts, P/N 63-9587-1, accomplish the following: (a) Conduct a heat-treat check on the attach bolts, P/N 63-9587-1 (two per actuator beam). (b) Bolts testing within the heat-treat range of 180,000 p.s.i. to 2000,000 p.s.i. are acceptable for further use and may be continued in service provided they are not otherwise defective. (c) Bolts testing outside the heat-treat range of 180,000 p.s.i. to 200,000 p.s.i. shall be replaced with bolts of proper heat-treat before further flight. (d) If holes in either the actuator beam or the terminal are damaged during bolt removal, the bolt holes, or the bolts may be reworked in accordance with Boeing Service Bulletin No. 1827, or an FAA equivalent approved method.
