What was found
DURING PREFLIGHT CHECKS, HYDRAULIC FLUID WAS DISCOVERED IN THE RT MAIN LANDING GEAR WHEEL WELL. ON FURTHER INVESTIGATION, A HYDRAULIC LINE IN A GROUPING OF FOUR LINES WAS FOUND TO BE CHAFED ON THE AIRCRAFT STRUCTURE, ROUGHLY AN INCH FROM THE B-NUT FITTING. SPI-WRAP WAS IN PLACE ON ALL THE HYDRAULIC LINES IN THIS AREA, BUT THE SPI-WRAP FOR THE HYDRAULIC LINE IN QUESTION WAS OUT OF POSITION CAUSING THE LINE TO CHAFE ON A GEAR WELL BRACKET. THE SUSPECT AREA CAN BE VIEWED THRU THE RIGHT MAIN LANDING GEAR WHEEL WELL BY OPENING THE INBD GEAR DOOR AND VIEWING AFT AND OUTBOARD.
