## Discrepancy

AIR RETURN, DURING RT AIR DATA TEST, RIGHT ALTIMETER FAILED AND RED FLAGS OFF.  SWAPPED LEFT AND RIGHT ALTIMETER PROBLEM FOLLOWS.  NEEDS F/O'S ALTIMETER. IAW AMM 34-12-00PG 502, RAN ADC TEST AGAIN, F/O'S ALTIMETER WAS NORMAL (SUPPOSED TO FLAG DURING TEST),  HOWEVER CAPTAIN`S ALTIMETER NEVER FLAGGED,  EVEN WITH CIRCUIT BREAKER OUT. (FLAG STUCK OUT OF VIEW) REPLACED CAPTAIN`S ALTIMETER IAW AMM 34-13-00, OPS CHECKED NORMAL, ADC TEST NOW NORMAL BOTH SIDES IAW 34-12-00 PG 502.
