THE PLT CAME IN FOR HER 3RD LANDING AND AFTER FLARING HIGH'CUT'THE THROTTLE AND SAID SHE HOPED FOR A'SOFT'LANDING WITH TRIM BACK AND 40 DEGREES OF FLAPS. A PLT ON THE GROUND NEAR THE RWY SAID HIS ATTENTION WAS DRAWN TO THE ACFT BECAUSE OF A LARGE INCREASE IN ENGINE NOISE. HE SAID THE ACFT NOSE WAS HIGH,AIRSPEED SLOW AND THE ACFT APPEARED TO ENTER A'TORQUE ROLL'. HE ADDED IT POSSIBLY ROLLED DUE TO'P'FACTOR. THE LEFT WING HIT THE GROUND FIRST AND THE ACFT CAME TO REST ABOUT 200 FT OFF THE RWY. THE PLT SAID SHE MAY HAVE RAISED THE FLAPS TO GO AROUND BEFORE ADDING POWER. SHE ALSO SAID SHE MAY NOT HAVE USED ENOUGH RUDDER TO CORRECT FOR THE ADDED POWER. HER INSTRUCTOR SAID SHE TENDED TO USE TRIM INSTEAD OF RUDDERBUT HE THOUGHT SHE WAS'CURED'OF HER HABIT OF RAISING FLAPS BEFORE POWER BUT A'REFLEX SITUATION'MAY HAVE MADE HER HAVE THE PREDOMINANT IMPROPER REFLEX ACTION.
