To prevent the most forward aileron control system pulley, mounted on the lower portion of the control column, from separating from its bearing, accomplish the following:

Remove the bolt attaching the most forward aileron control system pulley to the control column. Replace pulley assembly with the addition of washers AN 970-5 and AN 960-516 and an AN 5-27 bolt instead of the original bolt in the following order from front to rear:

1. AN 5-27 bolt, head forward. 2. AN 970-5 washer. 3. AN 960-516 washer. 4. Original pulley. 5. Control column. 6. AN 960-516 washer. 7. AN 365-524 nut

or equivalent approved by Chief, Engineering and Manufacturing Branch, FAA Southern Region.

Maule Service Letter No. 19, dated September 4, 1969, covers this same subject.
