Compliance: Required as indicated, unless already accomplished.

To prevent failure of the P/N 45-524504 and 45-524505 rudder-aileron bungee interconnect cable assembly and the P/N 45-524697 or P/N 45-524028 bellcrank assembly, accomplish the following:

A) On Model A45 (Military T-34A, B-45) airplanes not incorporating P/N MS- 20219-2 pulleys (1.75 inch O.D.) per Beech Kit 45-325 and Beech P/N 105740B-ZF-0105 bronze bushings per Beech Drawing 45-000060, Rev. C, or later revision, within 50 hours' time in service after the effective date of this AD, or within 100 hours' time in service after the last inspection per AD 62-27-01, and thereafter at intervals not to exceed 100 hours' time in service from the last inspection, accomplish Paragraphs 1(a) and 1(b).

B) On Models A45 (Military T-34A, B-45) and D45 (Military T-34B) airplanes incorporating P/N MS-20219-2 pulleys (1.75 inch O.D.) per Beech Kit 45-325 and Beech P/N 105740B-ZF-0105 bronze bushings per Beech Drawing 45-000060, Rev. C, or later revision, within 50 hours' time in service after the effective date of this AD, and thereafter at intervals not to exceed 300 hours' time in service from the last inspection, accomplish Paragraphs 1(a) and 1(b).

1. (a) Disconnect the turn buckles P/N 45-524504 and 45-524505 rudder-aileron bungee interconnect cable assemblies, visually inspect the cables and replace frayed, internally broken or excessively worn cables.

If elongation exceeds 0.02 inches or if cracks are found, replace the bellcrank. If no elongation or cracks are found, lubricate the holes in the bellcrank prior to reinstallation of the AN 161-8RS forks.

2. The airplane may be flown in accordance with FAR 21.197 to a location where parts replacement can be accomplished.
