ENG QUIT DURING PRACTICE FORCED LNDG CAUSING AN ACTUAL FORCED LNDG.

Narrative

ON AUG/THU/92 AT APPROX XY10 AM LCL TIME SMA X EXPERIENCED A FORCED LNDG IN A FIELD S OF LABELLE; FL. THERE WAS NO VISIBLE DAMAGE TO THE ACFT AND NO INJURIES TO THE CREW. AN EMER WAS NOT DECLARED. THE FLC CONSISTING OF RPTR (INSTRUCTOR PLT) AND STUDENT PLT WERE PRACTICING SIMULATED ENG FAILURES AND GND REF MANEUVERS OVER A VERY LARGE FIELD. AT APPROX 1800 FT AGL; THE INSTRUCTOR PLT APPLIED CARB HEAT AND ENSURED THE MIXTURE CTL WAS FULL RICH PRIOR TO RETARDING THE THROTTLE FOR A SIMULATED ENG OUT APCH. DURING THE DSCNT; THE ENG WAS OCCASIONALLY 'CLRED' BY ADVANCING THE THROTTLE TO INCREASE ENG RPM. AN EXCELLENT APCH (FORTUNATELY) TO THE FIELD WAS MADE BY THE STUDENT AND FLAPS FULL WERE APPLIED. AT APPROX 500 FT AGL; A GAR WAS INITIATED BY SMOOTHLY ADVANCING THE THROTTLE. THE ENG MADE A RATHER MUFFLED POPPING SOUND AND PRODUCED A NEGLIGIBLE AMOUNT OF PWR. THE PROP CONTINUED TO ROTATE DURING THE GLIDE UNTIL THE LNDG FLARE WHERE IT ALMOST STOPPED; THEN ROTATED AGAIN; THEN FINALLY STOPPED. AT THIS POINT THE CREW APPLIED MIXTURE LEAN. THE AIRPLANE SUFFERED NO VISIBLE DAMAGE AND THE CREW UNINJURED AS A RESULT OF THE FORCED LNDG. AFTER INSPECTING THE AIRPLANE; ENG; AND PROP FOR DAMAGE; THE MASTER SWITCH WAS TURNED ON AND CONTACT WITH FT MYERS APCH WAS INITIATED. SINCE TURNING THE MASTER SWITCH ON AND OFF TO SAVE THE BATTERY PWR WAS IMPRACTICAL FOR COM; THE CREW ELECTED TO ATTEMPT AN ENG START. THE ENG REACTED LIKE IT WAS 'FLOODED' DURING THE RESTART ATTEMPT BUT; AFTER THE THIRD TRY IT STARTED AND REMAINED OPERATING FOR THE ENTIRE SEARCH AND RESCUE TO ENSURE ELECTRICAL PWR FOR COM. AT THE REQUEST OF FT MYERS APCH; THE ELT WAS ACTIVATED FOR A CUMULATIVE 25 MINS.
