WHILE RETURNING TO THE AIRPORT AFTER SPRAYING CROPS, THE PILOT NOTED A CHANGE IN THE ENGINE SOUND AND NOTICED A LOSS OF OIL PRESSURE. ANTICIPATING AN IMMINENT ENGINE FAILURE, THE PILOT LANDED ON A PORTION OF AN OLD HIGHWAY THAT WAS CLEAR OF MOTOR VEHICLES. AFTER ROLLING ABOUT 75 TO 100 YARDS ON A STEEP GRADE, THE RIGHT WING TIP HIT SMALL GUM TREES. ON THE OPPOSITE BANK OF THE ROAD WERE A DENSE CLUMP OF PLUM TREES THAT WERE SOMEWHAT SMALLER. THE PILOT REPORTED THAT THE AIRCRAFT WAS PRECISELY ON THE CENTERLINE OF THE ROAD AT ABOUT 50 MPH WHEN IT STRUCK THE TREES. THE AIRCRAFT THEN SWERVED TO THE RIGHT AND HIT A DITCH. AN EXAMINATION REVEALED THAT A FLEXIBLE OIL LINE (SR2800-8-0390-64228-6 TSO C53A TYPE C SEPT 74 PT) RUPTURED AND ALLOWED A LOSS OF ENGINE OIL AND PRESSURE.
