46-38-02 ERCO: (Was Mandatory Note 8 of AD-718-6.) Applies to 415-C, -CD and -D Aircraft Serial Numbers 113 to 2706 Except 2683, 2685, 2687, and 2691.
Compliance required prior to November 1, 1946.
(a) To provide additional bearing area and more positive locking action for the aileron control stop adjustment screw, add an AN 315-3R nut on the adjustment screw at the forward side of the stops and a star type AN 936-B10 lock washer (external teeth) between the jam nut and rear side of stops (Ercoupe P/N 415-52145).
(b) Inspect the welds which attach the aileron control stops to the control column cross member carefully for cracks. Also determine that welds are complete around the ends of the stops. Repair if cracked welds or insufficient welds are found.
(c) Inspect the adjustment of the two upper turnbuckles in the chain and cable system to be certain these turnbuckles do not touch the sprockets before the quadrant touches the stops. Readjust all three turnbuckles if necessary to insure freedom from this turnbuckle-sprocket interference.
