## Discrepancy

PILOT REPORTED HIS ENCODING ALTIMETER WAS INOPERATIVE ON TAKEOFF.  THIS SITUATION ALSO RENDERED THE ALTITUDE ALERTER AND TRANSPONDER MODE C INOPERATIVE.  EXCESS FUEL WAS BURNED OFF AND THE ACFT RETURNED TO BASE.  MX REPLACED THE PILOT'S ENCODING ALTIMETER, PERFORMED A SYS LEAK CHECK, AND RECERTIFIED THE TRANSPONDER SYS.  ACFT WAS THEN RELEASED FOR SERVICE.
