## Discrepancy

THIS AIRCRAFT WAS MANUFACTURED IN 1944 WITH CASEIN GLUE USED FOR BONDING ALL WOOD STRUCTURE INCLUDING WINGS, FLAPS, AILERONS, AND CABIN ROOF.  INSPECTION DURING RESTORATION FOUND MANY GLUED JOINTS DISBONDED WITH ONLY THE NAILS AND FABRIC COVERING HOLDING THE JOINTS TOGETHER.  ALL REPAIRS MADE USING RESORCINOL GLUE AS CASEIN GLUE IS NO LONGER RECOMMENDED IN AC43.13-1.
