C. The clip, P/N 206-001-391, must be mounted on the left hand outboard side of the clevis of the yoke, P/N 206-001-322, with the .38 by .16 inch tang of the clip against the top surface of the yoke pointing inboard.

(Figure 1 in Bell Helicopter Company Service Letter No. 206A-104, Revision B, dated January 17, 1969, and Bell Helicopter Company information letter dated May 16, 1969, pertain to this subject).
