Narrative:

Loss of engine power during training flight. Then noticed oil pressure had dropped to 0. Immediately turned south toward known grass strip and fields. Engine quit completely. Completed engine failed checklist. Landed in cow pasture. No external damage to aircraft or cow pasture. Checked oil after landing, found to have same amount of oil that we departed with. Engine vibrated badly just prior to shutdown. I believe oil pump failure to have caused the problem. Landing was good--not a scratch. I feel that the actions of my instrument and also those of myself to have been excellent in that it was a safe and uneventful landing. I contribute this to proper training toward emergencys. The training of pilots to meet emergencys is the most important aspect of all pilot training.

Title: STUDENT AND FLT INSTRUCTOR LOSE OIL PRESSURE, EXPERIENCE ENGINE FAILURE. SUCCESSFUL FORCED LNDG RESULTS.

Narrative: LOSS OF ENG PWR DURING TRNING FLT. THEN NOTICED OIL PRESSURE HAD DROPPED TO 0. IMMEDIATELY TURNED S TOWARD KNOWN GRASS STRIP AND FIELDS. ENG QUIT COMPLETELY. COMPLETED ENG FAILED CHKLIST. LANDED IN COW PASTURE. NO EXTERNAL DAMAGE TO ACFT OR COW PASTURE. CHKED OIL AFTER LNDG, FOUND TO HAVE SAME AMOUNT OF OIL THAT WE DEPARTED WITH. ENG VIBRATED BADLY JUST PRIOR TO SHUTDOWN. I BELIEVE OIL PUMP FAILURE TO HAVE CAUSED THE PROB. LNDG WAS GOOD--NOT A SCRATCH. I FEEL THAT THE ACTIONS OF MY INSTR AND ALSO THOSE OF MYSELF TO HAVE BEEN EXCELLENT IN THAT IT WAS A SAFE AND UNEVENTFUL LNDG. I CONTRIBUTE THIS TO PROPER TRNING TOWARD EMERS. THE TRNING OF PLTS TO MEET EMERS IS THE MOST IMPORTANT ASPECT OF ALL PLT TRNING.
