## Discrepancy

IMMEDIATELY AFTER TAKEOFF FROM SLC, LEFT AND RIGHT IAS MESSAGES APPEARED FOLLOWED BY STALL FAIL, MACH TRIM ALSO HIGH PITCH NOISE FOLLOWED BY VERY UNRELIABLE AIRSPEED INDICATION FROM CO-PILOTS AIRSPEED INDICATOR.  AS AIRCRAFT SLOWED DOWN, LOUD NOISE WENT AWAY.  RETURNED TO SLC.  PITOT STATIC OPS CHECKS PITOT STATIC SYSTEM IAW MM 34-11-00.  VERIFIED PITOT STATIC DRAINS CONTAINED NO WATER.  UNABLE TO DUPLICATE SYSTEM FAILURE OR HAVE ANY HIGH PITCHED NOISES.
