What was found

UPON RETURN, HYDRAULIC LINE ON THE AILERON PCU HYDRAULIC B SYS IN THE LT WHEEL WELLWAS FOUND LEAKING UNDER THE ATTACH FITTING. UNABLE TO SEE DAMAGE OR LEAK BY GVI, BUT TEFLON SLEEVE SEEMS TO SLIP DOWN AND SINCE THOSE LINES HAVE A PRONOUNCED BEND RADIUS AND LOT`S OF MOVEMENT FROM THE UNIT THAT IT IS ATTACHED TOO, WE SUSPECT WEAR OF THE METAL BRAIDS.
