## Discrepancy

THE PILOTS ALTIMETER FLAGGED WHILE ENROUTE.  THE FLIGHT CREW NOTIFIED ATC.  SEVERAL MINUTES LATER THE ALTIMETER BEGAN WORKING NORMALLY.  THE CONNECTIONS WERE CHECKED AND A BITE TEST WAS PERFORMED ON THE ADC WITH NO DEFECTS NOTED.  AC WAS RETURNED TO SERVICE AND CONTINUED FLIGHT.  WHILE ON THE GROUND, THE ALTIMETER AND ADC CONNECTIONS WERE RECHECKED.  BOTH PRIMARY ALTIMETERY SYSTEMS WERE RUN TO ALTITUDE USING A DPS 500 AND NO DEFECTS WERE NOTED.  THERE HAVE BEEN NO PRIOR REPORTS OF ALTIMETERY ERRORS ON THE AIRCRAFT.  (K)
