47-41-08 BELL: (Was Mandatory Note 20 of AD-1H-2.) Applies to All Models of 47B Series, Through Serial Number 78.
Compliance required at next 100-hour inspection.
The stabilizer bar mixing levers should be reworked by cutting away the lower inboard edge of a 2-inch radius from a center position 1 1/2 inches from the vertical centerline of the center hole. The cut should not be more than 1/8 inch at its deepest point and the sharp corners, resulting from the removal of this segment, should be rounded by a 1/2-inch radius. This reworking will eliminate the interference between those levers and the stabilizer bar damper, which may exist when the stabilizer bar is depressed 5 degrees.
(Complete instructions are carried by Bell Service Bulletin 47C52, dated July 9, 1947.)
