## Discrepancy

EMERGENCY LANDING MADE DUE TO OIL LOSS AND PRESSURE LOSS.  FOUND OIL LOSS AT APPROXIMATELY 1 QUART PER MINUTE AT 1,000 RPM.  REMOVED PROPELLER AND FOUND FLANGE CRACKED 50 PERCENT AROUND CIRCUMFERENCE OF FLANGE.  FAILURE OF CRANKSHAFT (LOSS OF PROPELLER) WAS VERY LIKELY TO HAPPEN AT ANY TIME.  NOTE:  THIS INSTALLATION IS A COLEMILL CONVERSION.  VAR CRANKSHAFT NOT INSTALLED.
