## Discrepancy

DURING PREFLIGHT OF AIRCRAFT PILOT REPORTED OIL LEAKING FROM ENGINE.  MAINTENANCE TECHNICIAN FOUND OIL LEAK ON OIL COOLER.  PERFORMED PRESSURE CHECK ON OIL COOLER AND FOUND TOP FLANGE CRACKED.  THIS IS A WEAK AREA ON THE OIL COOLER.  RECOMMEND FINDING A REPLACEMENT THAT IS MORE DURABLE.
