Narrative

THE PURPOSE OF THE FLT WAS TO EVALUATE A STUDENT ON SHORT AND SOFT FIELD TKOFS AND LNDGS AND 180 DEG ACCURACY LNDGS. THE FLT ORIGINATED AT XA30 AM LCL ON MAY/TUE/95 AT RUSTON REGIONAL ARPT; RUSTON; LA. THE WX WAS CLR; VISIBILITY WAS ABOUT 7 MI AND THE WINDS WERE ABOUT 12 KTS AND 'BUMPY.' THE STUDENT FLEW THE AIRPLANE THE ENTIRE FLT. HE PERFORMED 4 LNDGS SAFELY. THE LAST LNDG WAS A 180 DEG ACCURACY LNDG. ONCE ABEAM THE RWY NUMBERS; THE STUDENT PULLED THE THROTTLE TO IDLE AND STARTED A GLIDING TURN TOWARD THE RWY AT 75-80 KTS. UPON TURNING FINAL APCH EVERYTHING WAS NORMAL AND THE STUDENT APPEARED TO BE ABLE TO LAND ON THE RWY NUMBERS (HIS INTENDED LNDG SPOT). JUST BEFORE THE STUDENT BEGAN TO FLARE I CHKED THE AIRSPD AND IT WAS 75 KTS. JUST BEFORE TOUCHDOWN THE ACFT BEGAN TO SINK TO THE RWY. THE STUDENT ADDED FULL PWR AND THE ACFT LANDED HARD. HE THEN TAXIED TO THE RAMP.
