## Discrepancy

THE PILOT REPORTED A ROUGH ENGINE AND MADE A PRECAUTIONARY LANDING.  A COMPRESSION GAUGE REVEALED THE NR 2 CYLINDER LEAKING BETWEEN THE HEAD AND BARREL (6 INCHES FROM THE MOUNTING FLANGE).  THIS IS BETWEEN THE COOLING FINS AT THE BASE OF THE EXHAUST PORT.  THE CRACK IS ABOUT 4 INCHES LONG.  THE CYLINDER WAS WAS REMOVED AND A NEW ONE INSTALLED.
