Narrative:

Under a VFR flight plan in an small aircraft, a student and myself (instructor) initiated a missed approach, making a practice instrument approach in VFR conditions at timmerman airport. When my student brought up the power to climb, we noticed a significant yaw in the airplane. I requested clearance to land at timmerman. Upon receiving my landing clearance, I looked over at the left engine's oil pressure -- it indicated below 0. Upon reverifying the fact that the left engine was not producing power, I feathered the engine and landed. I did not declare an emergency nor have I contacted the FAA, feeling that this isn't a rptable accident or incident.

Title: SMA ON PRACTICE ILS APCH HAS PWR LOSS, FORCED LNDG.

Narrative: UNDER A VFR FLT PLAN IN AN SMA, A STUDENT AND MYSELF (INSTRUCTOR) INITIATED A MISSED APCH, MAKING A PRACTICE INST APCH IN VFR CONDITIONS AT TIMMERMAN ARPT. WHEN MY STUDENT BROUGHT UP THE PWR TO CLB, WE NOTICED A SIGNIFICANT YAW IN THE AIRPLANE. I REQUESTED CLRNC TO LAND AT TIMMERMAN. UPON RECEIVING MY LNDG CLRNC, I LOOKED OVER AT THE L ENG'S OIL PRESSURE -- IT INDICATED BELOW 0. UPON REVERIFYING THE FACT THAT THE L ENG WAS NOT PRODUCING PWR, I FEATHERED THE ENG AND LANDED. I DID NOT DECLARE AN EMER NOR HAVE I CONTACTED THE FAA, FEELING THAT THIS ISN'T A RPTABLE ACCIDENT OR INCIDENT.
