## Discrepancy

(CAN) DURING DESCENT, CHIP WARNING LITE ILLUMINATED. MAINTENANCE PERSONNEL THEN CLEANED CHIP PLUG  & CHANGED FILTER. SERVICEABILITY CHECK CARRIED OUT AS PER BOEING MAINTENANCE MANUAL SECTION 63-25-00 & 63-23-00 AND TRANSMISSION FOUND SERVICEABLE. HOWEVER, ROTORCRAFT WAS FERRIED TO AMO FOR PRECAUTIONARY REPLACEMENT OF TRANSMISSION.
