## Discrepancy

THIS ENGINE WAS INSTALLED NEW ON A HOMEBUILT KIT VAN RV-6 AIRCRAFT.  DUIRNG CRUISE FLIGHT, THE PROPELLER BECAME LOOSE CAUSING A VIBRATION.  THE FRONT CRANKSHAFT COMPRESSION PLUG OPENED AND OIL WAS ALLOWED TO FLOW OUT AROUND THE BACK OF THE PROPELLER.  SUBMITTER STATED TEXTRON LYCOMING SI 1435 WAS NOT C/W WHICH WOULD HAVE ALLOWED OIL TO RETURN TO THE SUMP.
