## Analysis

THE AIRCRAFT COLLIDED WITH A TELEPHONE POLE WHILE ATTEMPTING A TAKEOFF ON SKIS. THE SNOW WAS WET, SPARSE AND STICKY AND THE TAKEOFF WAS BEING PERFORMED ON A TAXIWAY BECAUSE IT HAD MORE SNOW. THIS WAS A DUAL INSTRUCTIONAL FLIGHT WITH THE STUDENT AT THE CONTROLS. THE STUDENT ROTATED PREMATURELY, STALLED AND SETTLED BACK ON THE SNOW. THE TAKEOFF WAS CONTINUED AND AFTER A 2ND LIFT OFF THE AIRCRAFT AGAIN ENTERED A STALL. THE CFI TOOK OVER AND IN LOWERING THE NOSE TO GAIN AIRSPEED AND TURNING TO AVOID TREES THE WING HIT A TELEPHONE POLE. THE AIRCRAFT THEN CARTWHEELED AND WAS DAMAGED BEYOND ECONOMICAL REPAIR.
