THE PILOT WAS CRUISING AT 4500 FEET WHEN HE OBSERVED A LOW OIL PRESSURE INDICATION FOLLOWED BY A TOTAL LOSS OF ENGINE POWER. THE PILOT PERFORMED A FORCED LANDING ON AN OPEN FIELD, DURING WHICH THE NOSE GEAR COLLAPSED, AND THE FIREWALL BUCKLED. THE FAA INSPECTOR STATED THAT ALL PISTON PINS WERE REUSED AT LAST OVERHAUL, 121 HOURS PRIOR TO THE ACCIDENT. DURING POSTACCIDENT EXAMINATION, ALL PISTON PINS WERE FOUND TO BE BELOW SERVICE LIMITS. ADDITIONALLY, '...THE ENGINE FAILURE RESULTED FROM METAL PARTICLES GENERATED BY THE LOOSE FITTING PISTON PIN PLUGS, CAUSING PROGRESSIVE CONTAMINATION OF THE ENGINE LUBRICATION SYSTEM.'
Probable Cause: THE LOSS OF ENGINE POWER DUE TO IMPROPER MAJOR OVERHAUL OF THE ENGINE BY THE REUSE OF WORN PISTON PINS. THE ROUGH/ UNEVEN TERRAIN IN THE EMERGENCY LANDING AREA WAS A FACTOR.
