Narrative

THE EVENT OCCURRED DURING AN SMA TRAINING FLT. 2 TAILWHEEL-QUALIFIED CFI'S WERE ON BOARD WITH THE FRONT SEAT PLT FLYING TO GAIN FAMILIARITY WITH TEACHING FROM THE FRONT SEAT. CARB HEAT WAS APPLIED AND THE THROTTLE CLOSED IN PREPARATION FOR A PWR OFF STALL AT 2000 FT AGL. AS THE NOSE OF THE ACFT APCHED A STALL ATTITUDE; THE PROP STOPPED ABRUPTLY. CONDITIONS WERE CONDUCIVE TO CARB ICING; THE AIR TEMP AND DEW POINT WERE 53 DEGS F AND 44 DEGS F; RESPECTIVELY. THESE PARAMETERS PLOT IN THE REGION OF MAX CARB ICE PROBABILITY ON A TEMP/DEW POINT PROBABILITY CHART. THE THROTTLE HAD BEEN CLOSED FOR APPROX 10 SECONDS. THE REAR SEAT PLT ASSUMED CTL OF THE AIRPLANE; SELECTED A LNDG SITE IN THE HILLY FARMLAND BELOW; UNSUCCESSFULLY ATTEMPTED A RESTART BY DIVING THE NON-STARTER EQUIPPED AIRPLANE; AND EXECUTED A LNDG UPHILL ON A SOFT SLOPE OF APPROX 10 PERCENT GRADE. THE GEAR COLLAPSED ON LNDG RESULTING IN MINOR DAMAGE TO THE ACFT BUT NO INJURIES TO THE OCCUPANTS. POSSIBLE CONTRIBUTING FACTORS: CARB ICING CONDITIONS. ALTHOUGH FULL CARB HEAT WAS APPLIED PRIOR TO CLOSING THE THROTTLE; THE HEAT MAY HAVE BEEN INSUFFICIENT.
