In some instances, the lower 3/16-inch bolts, when being checked for tightness, have broken. In order to overcome the difficulty, the stabilizer attaching fittings should be reworked and bolts be replaced with high heat-treated bolts. \n\n\t(Douglas Service Bulletin DC-4 No. 11, covers this same subject.)
