## Discrepancy

ON THE TUBE, WHERE BOLT HOLE IS DRILLED THAT MOUNTS TO THE FRONT BRACKET ON STABILATOR, A HOLE IS IN TUBE, (90 DEGREE ANGLE TO THE BOLT HOLE).

THIS EXTRANEOUS HOLE IS AT THE HIGH STRESS POINT IN THE TUBE AND HAS NOT BEEN ON ANY OF THE TUBES THAT HAVE BEEN INSPECTED FOR THE AD ON THE TUBES.   HOLE WAS FOUND WHEN REMOVING THE THICK LAYER OF BLACK PAINT DOWN TO THE ZINC CHROMATE IN AREA THAT FITS INTO THE STABILATOR BRACKETS.
