## Discrepancy

PILOT & CREW WAS ON A PATIENT TRANSFER FLIGHT WHEN THE ENG CHIP LIGHT ILLUMINATED.  PILOT WAS FLYING DIRECTLY OVER MARSHALL, TX AIRPORT & MADE AN IMMEDIATE LANDING WITHOUT ANY FURTHER ISSUES.  PULLED BOTH UPPER & LOWER CHIP DETECTORS & FOUND FLAKES & CHUNKS THAT MEASURED AROUND .0625 INCHES.  THIS  EXCEEDS THE .032 INCHES IAW M250-C47B, 72-00-00, 8 E 2 B.  ENG CHANGE IN PROGRESS.
