Aircraft Accident/Incident Report

New Roades, Louisiana 70760
Wednesday, August 1, 1990 17:00 CDT

NTSB Narrative Summary Released at Completion of Accident

DURING THE INSTRUCTIONAL FLIGHT, THE ENGINE SUFFERED A SUDDEN LOSS OF OIL PRESSURE, AND DURING THE FORCED LANDING, THE AIRPLANE NOSED OVER TO THE INVERTED POSITION. AS THE OIL PRESSURE WAS DROPPING, SO WAS THE ENGINE RPM. THERE WAS VERY LITTLE OIL IN THE SYSTEM AFTER THE ACCIDENT AND THE OIL HAD BEEN BLOWING OUT THE ENGINE BREATHER SYSTEM. THE OPERATOR SAID THAT AFTER THE WRECKAGE HAD BEEN RECOVERED, THEY HAD BLOCKED OFF THE ENGINE BREATHER SYSTEM AND THEN HAD PRESSURIZED IT TO 15 PSI, BUT COULD NOT FIND ANYTHING MECHANICAL THAT MIGHT HAVE PRESSURIZED THE CRANKCASE IN FLIGHT.

NTSB Probable Cause Narrative

UNKNOWN MECHANICAL MALFUNCTION RESULTING IN ENGINE OIL STARVATION. A CONTRIBUTING FACTOR WAS ROUGH TERRAIN IN WHICH THE FORCED LANDING WAS MADE.
