## Discrepancy

DURING FLIGHT TORQUE MISCOMP LIGHT ILLUMINATED, REDUCED POWER & LIGHT WENT OUT.  ACFT RETURN TO BASE & LIGHT CAME ON AGAIN DURING HOVER FOR LANDING.  ACFT LANDED & LIGHT REMAINED ON ALONG WITH AN ALTN DATA FAIL LIGHT.  TECH REP RECOMMENDED CHECKING THE PLUGS AT THE PRIMARY & SECONDARY TRANSDUCERS.  ALSO STATED IT COULD POSSIBLY BE ONE OF THE SIGNAL CONDITIONERS.  THE PLUGS AT THE TRANSDUCERS WERE CLEANED & STABILENT 22 WAS APPLIED TO THE PINS.  THE ACFT WAS FLOWN FOR ABOUT 20 MIN AT DIFFERENT TORQUE SETTINGS, SPEEDS & ALTITUDES. THE PROBLEM COULD NOT BE DUPLICATED.  ACFT WAS RETURNED TO SERVICE.
