What was found
AIR CONDITIONING SYSTEM STC NR SR00463DE UTILIZES RIGID FREON LINES RUNNING FORE AND AFT ON THE ENGINE DECK. AT THE FORWARD END, THESE LINES CONNECT TO FLEX LINES. AT THIS CONNECTION THE LINES WERE SWAPPED. THE CONNECTIONS ARE LOCATED RIGHT NEXT TO EACH OTHER AND THE LINES RUN PARALLEL, MAKING THIS A VERY EASY MISTAKE. THESE LINES SHOULD UTILIZE DIFFERENT FITTINGS TO PREVENT THIS FROM HAPPENING.
