## Discrepancy

THE BS 1342, RBL 18 CHANNEL WAS FOUND SEVERELY RUSTED WHERE IT ATTACHES TO THE STRUCTURE.  DEFECT WAS DISCOVERED DURING A RE-ENGINING MODIFICATION.  THIS CONDITION HAS BEEN FOUND ON ALL 38 AIRCRAFT MODIFIED THUS FAR.  CONDITION IS PROBABLY CAUSED BY DISSIMILAR METAL AND LACK OF DRAINAGE.  NOTE:  THE RUST CANNOT BE SEEN WITHOUT REMOVING THE PART, MAY NEED TO BE X-RAYED EVERYY SO MANY YEARS.
