REGULATORY TEXT:  
58-20-01 CURTISS-WRIGHT: Applies to all C-46 Series aircraft P/N 20-360-1058-2 (Tail Wheel Retract Yoke).

Compliance required at next regular inspection, but not later than December 1, 1958.

Several P/N 20-360-1058-2 tail wheel retract yokes have been found cracked or broken. Many of these parts have had a radius at the base of the yoke of less than the required 0.120 inch.

As a result of these failures, the subject parts must be inspected for the proper radius and magnetic particle, or equivalent inspection for cracks at the base of the yoke.

Parts which have a radius at the base of the yoke of less than 0.110 inch or in which cracks are found, are considered unairworthy and must be replaced.
