46-06-05 STINSON: (Was Service Note 1 of AD-556-1.) Applies to All Model A Aircraft.
After each 100 hours of operation, make a visual inspection (using at least a 4-power magnifying glass) of the main spar lower fittings at the outer wing panel to inner wing panel connection for small fatigue cracks at the fish-mouth weld connecting the fittings to the chord tubes of the spar. These cracks are most likely to originate at the inboard corners of the fish- mouth weld on the outer panel fitting. If any cracks are found, repairs should be made before further operation of the aircraft. Proposed methods of repair should be submitted for engineering approval.
