## Discrepancy

(CAN) DURING CRUISE, THE RT ENGINE BETA LIGHT ILLUMINATED. ALL PROPELLER AND ENGINE PERFORMANCE WAS NORMAL. THE FLIGHT CREW SHUT DOWN THE AFFECTED ENGINE AND FEATHERED THE PROPELLER AS A PRECAUTION. THE AIRCRAFT RETURNED TO THE AIRPORT.  UPON INVESTIGATION, MAINTENANCE DISCOVERED THE FAULT WAS WITH THE BETA LIGHT SWITCH WIRE. THE WIRE WAS REPAIRED AND THE SYSTEM FUNCTION CHECKED SERVICEABLE AND THE AIRCRAFT WAS RETURNED TO SERVICE.
