## Discrepancy

THE AIRCRAFT WAS BEING TOWED FROM THE HANGER AFTER OVERNIGHT MAINTENANCE IN CWA.  THE AMT IN THE COCKPIT SELECTED THE HYD PRES SWITCH FOR HYDRAULIC PRESSURE, NEEDED TO SET THE BRAKES.  AS THE SYSTEM NEARED "FULL CHARGE" THE ACCUMULATOR BURST, CAUSING SUBSEQUENT DAMAGE TO THE NOSE SECTION OF THE AIRCRAFT.  REPLACED ACCUMULATOR.
