Narrative:

Training flight with student and instrument. Cruising from tgc airport to mkl (home base) at 1500' MSL, heading 170 degrees, instrument decided to do an emergency engine out procedure. After looking out for obstacles and some usable fields, instrument pulled carburetor heat and throttle. The student immediately establishes best glide, looked for a field then executed a simulated restart procedure. He then turned the aircraft into the wind toward the selected field. At about 750-800' MSL, the approach to the field looked ok and the instrument decided to do the go around. When power was applied, the RPM did not come back and the descent continued toward the field. As instrument, I now took control of the aircraft. Throttle was manipulated and some power gradually came back. Instrument tried to fly out of the field but air speed and altitude were still low. Evasive action then had to be taken to avoid trees at the end of the field. To build airspeed, the nose was pitched down into the next field and power was now starting to come back. To avoid low slow turns, we were still heading into the wind (reported sfc winds out of 300). And since the time was late afternoon, we were also heading into the sun. This prevented the pilots from seeing some power lines crossing the field until too late. Immediate pull up did not prevent the aircraft from hitting one of the lines with the propeller. The engine was now producing about 2200 RPM, and we were able to slowly climb to 1500' and make a normal flight and landing back at mkl. Damage to propeller and power line was reported immediately.

Title: INSTRUCTOR AND STUDENT EXPERIENCED ENGINE PROBLEMS EXECUTING PRACTICE FORCED APCH. SUFFERED WIRE STRIKE ON GO AROUND.

Narrative: TRNING FLT WITH STUDENT AND INSTR. CRUISING FROM TGC ARPT TO MKL (HOME BASE) AT 1500' MSL, HDG 170 DEGS, INSTR DECIDED TO DO AN EMER ENG OUT PROC. AFTER LOOKING OUT FOR OBSTACLES AND SOME USABLE FIELDS, INSTR PULLED CARB HEAT AND THROTTLE. THE STUDENT IMMEDIATELY ESTABLISHES BEST GLIDE, LOOKED FOR A FIELD THEN EXECUTED A SIMULATED RESTART PROC. HE THEN TURNED THE ACFT INTO THE WIND TOWARD THE SELECTED FIELD. AT ABOUT 750-800' MSL, THE APCH TO THE FIELD LOOKED OK AND THE INSTR DECIDED TO DO THE GAR. WHEN PWR WAS APPLIED, THE RPM DID NOT COME BACK AND THE DSNT CONTINUED TOWARD THE FIELD. AS INSTR, I NOW TOOK CTL OF THE ACFT. THROTTLE WAS MANIPULATED AND SOME PWR GRADUALLY CAME BACK. INSTR TRIED TO FLY OUT OF THE FIELD BUT AIR SPD AND ALT WERE STILL LOW. EVASIVE ACTION THEN HAD TO BE TAKEN TO AVOID TREES AT THE END OF THE FIELD. TO BUILD AIRSPD, THE NOSE WAS PITCHED DOWN INTO THE NEXT FIELD AND PWR WAS NOW STARTING TO COME BACK. TO AVOID LOW SLOW TURNS, WE WERE STILL HDG INTO THE WIND (RPTED SFC WINDS OUT OF 300). AND SINCE THE TIME WAS LATE AFTERNOON, WE WERE ALSO HDG INTO THE SUN. THIS PREVENTED THE PLTS FROM SEEING SOME PWR LINES XING THE FIELD UNTIL TOO LATE. IMMEDIATE PULL UP DID NOT PREVENT THE ACFT FROM HITTING ONE OF THE LINES WITH THE PROP. THE ENG WAS NOW PRODUCING ABOUT 2200 RPM, AND WE WERE ABLE TO SLOWLY CLB TO 1500' AND MAKE A NORMAL FLT AND LNDG BACK AT MKL. DAMAGE TO PROP AND PWR LINE WAS RPTED IMMEDIATELY.
