## Discrepancy

AT APPROXIMATELY10000 FT, WE HAD EXCESSIVE PRESSURE AND DELTA P LOTS OF BANGING SOUNDS. AUTO PILOT DISCONNECTED MULTIPLE TIMES, HAND FLOWN EXCESSIVE VIBRATION AND FLIGHT CONTROLS FELT OFF.  CORRECTIVE ACTION REMOVED AND REPLACED PRESSURE SWITCH OPS CHECK GOOD. INSPECTED FLIGHT CONTROLS NO DEFECTS FOUND. FUNCTIONAL FLIGHT CHECK SATISFACTORY.
