## Analysis

THE STUDENT WAS RECEIVING INSTRUCTION IN SOFT FIELD LANDINGS & RUDDER CONTROL DURING THE LANDING ROLL-OUT. A DOWNWIND APPROACH WAS MADE TO RWY 18 WHICH HAD A DOWNWARD GRADIENT OF 1.5%. FLAPS WERE USED FOR THE APPROACH & THE ACFT TOUCHED DOWN ABOUT 1/3 OF THE WAY DOWN THE RWY. AS THE WHEELS TOUCHED DOWN THE INSTRUCTOR (CFI) TOLD THE STUDENT TO 'BRING UP THE RPM TO ABOUT 12 INCHES & TO HOLD THE NOSE OFF THE RWY.' ABOUT HALF WAY DOWN THE RWY, HE WAS STILL HOLDING THE NOSE OFF. SUBSEQUENTLY, AS THEY STARTED TO RAISE THE FLAPS, THE ACFT ENCOUNTERED A GUST & THE LEFT WING LIFTED. THE STUDENT ADDED POWER & RAISED THE NOSE. THE CFI STATED THAT HE QUICKLY REDUCED THE POWER & APPLIED LEFT RUDDER & AILERONS. HE SAID THE ACFT BEGAN TO WHEELBARROW, TURNED LEFT INTO THE DIRT & SUBSEQUENTLY NOSED OVER. THE CFI REPORTED THE WIND WAS FROM 360 DEG AT 15 GUSTING 25 KTS.
