## Discrepancy

OIL COOLER IS PART OF A CERTIFIED ENGINE INST ON A CE-172M.  DURING CRUISE FLIGHT, THE OIL COOLER RUPTURED IN THE AREA OF THE END TANK ON THE OUTPUT SIDE OF THE COOLER.  THIS CAUSED A RAPID LOSS OF OIL AND ENGINE FAILURE.  ON-AIRPORT LANDING WITHOUT FURTHER DAMAGE.  IT IS SUSPECTED DURING MFG OF THIS PART, THE SOLDER FLUX WAS NOT THOROUGHLY CLEANED FROM THE TANK WHICH CAUSED A THINNING OF THE METAL.
