## Analysis

AFTER DEVELOPING AN OIL LEAK THE PILOT ELECTED TO MAKE A PRECAUTIONARY LANDING. THE AIRCRAFT ENCOUNTERED ROUGH TERRAIN ON TOUCHDOWN AND COLLAPSED THE NOSE GEAR AND NOSED OVER. THE PILOT AND ONE PASSENGER REPORTED NO INJURIES, HOWEVER THE AIRCRAFT WAS SUBSTANTIALLY DAMAGED. INVESTIGATION REVEALED THAT THE FITTING ON THE OIL RETURN LINE FROM THE OIL COOLER WAS LOOSE ALLOWING THE OIL SEAL TO BACK OFF.
