AG5B PLT MAKES AN OFF FIELD LNDG DUE TO LOSS OF PWR AND A MALFUNCTIONING ENG.

Narrative

WE TOOK OFF ON A BIENNIAL FLT REVIEW FROM HOOK FIELD (MWO) AT ABOUT XA30 PM. WE PROCEEDED TO DO STEEP TURNS AND SLOW FLT. I THEN INSTRUCTED THE STUDENT TO TURN EASTWARD; WHICH WAS THE DIRECTION BACK TO THE ARPT; AND BEGAN TO TALK TO HIM ABOUT EMER PROCS. HE THEN PROCEEDED TO BRING HIS PWR BACK TO ABOUT 1500 RPM. HE TALKED ME THROUGH HIS PROCS AND WHEN HE POINTED OUT WHICH FIELD HE WOULD HAVE LANDED IN; I TOLD HIM TO APPLY PWR AND GO AROUND. AT THIS TIME WE WERE APPROX 1000 FT AGL. WHEN HE ADVANCED THE PWR FROM 1500 RPM TO FULL RPM'S; THE ENG DID NOT RESPOND. IN FACT; WE EVEN LOST RPM. HE THEN PROCEEDED WITH PROPER EMER PROCS. ONCE WE DETERMINED WE WERE NOT GOING TO REGAIN ENOUGH PWR TO MAINTAIN FLT; HE EXECUTED AN OFF FIELD LNDG IN HIS PRE-DETERMINED FIELD; A SOYBEAN FIELD APPROX 5 NM N OF MIDDLETOWN ARPT (MWO). UPON EXAMINATION OF BOTH THE AIRPLANE AND FIELD; MYSELF; MY STUDENT; OUR PAX; AND THE OHIO STATE HWY PATROL OFFICER ALL AGREED THERE WAS NO DAMAGE TO THE AIRPLANE OR FIELD. THERE WERE ALSO NO INJURIES TO ANYONE ONBOARD. BECAUSE THERE WAS NO DAMAGE I DO NOT BELIEVE I NEEDED TO CONTACT THE FAA; HOWEVER; I DID. I SPOKE TO THE CINCINNATI FISDO THAT SAME DAY. SHE ADVISED ME SHE WOULD PROBABLY START A LITTLE PAPERWORK. WE ARE STILL WAITING TO FIND THE CAUSE OF THE ENG PROBS. I FIRMLY BELIEVE MY STUDENT AND I DID EVERYTHING POSSIBLE TO TROUBLESHOOT THE SIT. I AM ANXIOUS TO LEARN MORE ABOUT THE CAUSE AND TO LEARN HOW THIS SIT COULD HELP IN MY FUTURE FLYING CAREER.
