N3965M
PIPER PA-28R-201
THE CFI REPORTED THAT HE REDUCED PWR TO NEAR IDLE WITH THE THROTTLE, TO HAVE HIS STUDENT PRACTICE A SIMULATED FORCED LDG. THE ENGINE SUBSEQUENTLY LOST PWR COMPLETELY AT ABOUT 400-500 FT AGL WHEN HE ATTEMPTED TO ADD PWR BACK SO THAT THE STUDENT COULD INITIATE A GO-AROUND. SUBSEQUENT EFFORTS TO REGAIN PWR WERE UNSUCCESSFUL, AND A FORCED LDG WAS MADE IN A FIELD. THE CFI NOTED THAT HE HAD INCREASED THE PWR MOMENTARILY SEVERAL TIMES DURING DESCENT TO 'CLEAR' THE ENGINE, AND THAT HE WAS 'SLOWLY' OPENING THE THROTTLE WHEN THE ENGINE LOST PWR. POST-ACCIDENT EXAMINATION OF THE AIRPLANE AND ENGINE BY THE FAA REVEALED NO EVIDENCE OF ANY PRE-EXISTING MALFUNCTION OR FAILURE.
