## Discrepancy

THE ENG CHIP LIGHT ILLUMINATED IN CRUISE FLIGHT.  THE PILOT IMMEDIATELY DIVERTED TO A NEARBY AIRPORT & LANDED WITHOUT ANY FURTHER ISSUES.  THE MECHANIC ARRIVED & INSPECTED BOTH UPPER & LOWER ACCESSORY GEARBOX CHIP DETECTORS.  THEY BOTH SHOWED EXCESSIVE AMOUNTS OF METAL & WERE DETERMINED TO BE WELL BEYOND THE ALLOWABLE LIMITS.  THIS ACFT IS CURRENTLY OUT OF SERVICE, AT THE TIME OF THIS SUBMISSION, FOR AN ENG REPLACEMENT.
