What was found
DURING CLIMBOUT, NOTICED A MASTER CAUTION LIGHT FLASH. THEN A FEW SECONDS LATER IT DID IT AGAIN, LOOKED ALL AROUND AND SAW NOTHING. THEN IT CAME ON AND STAYED ON AND IT WAS THE RT OIL PRESSURE LIGHT. LOOKED AT THE GAUGE AND THE NEEDLE WAS IN THE RED. WENT TO THE CHECK LIST AND REDUCED POWER ON ENGINE. NO CHANGE ON THE GAUGE AND THE LIGHT WAS STILL ON. SO THE NEXT STEP WAS TO DO A PRECAUTIONARY ENGINE SHUTDOWN. RETURNED & LANDED WITH NO PROBLEMS. MX PERSONNEL CAME OUT TO LOOK AT THE ENGINE AND THERE WAS OIL ALL OVER THE ENGINE COWL. TESTS ARE BEING DONE TO SEE WHAT HAPPENED, BUT ON FIRST GLANCE THERE WAS METAL PIECES IN THE OIL FILTER AND OIL.
