What was found
UPON INSTALLATION OF A FUEL SELECTOR NOTICED THE OUTER COVER OF THE HOSE SPLIT AS IT WAS INSTALLED ON AN NIPPLE FITTING. AFTER CLOSE EXAMINATION, THE NEW HOSE SHOWS A MARK / CUT GOING THE LENGTH OF THE HOSE. IN SOME AREAS IT IS A MARK AND OTHER AREAS IT IS A CUT THROUGH THE OUTER LAYER OF THE HOSE. THE DEFECT IS STRAIGHT WITH NO WAVERING AND APPEARS LIKE IT CAME FROM THE MANUFACTURES EQUIPMENT THIS WAY. THIS MATERIAL REQUIRED REPLACEMENT OF ALL NEWLY INSTALLED HOSE ON THIS AIRCRAFT.
