THE PLT BEGAN TAKING OFF ON RWY 06 WITH A WIND FROM 190 DEG AT 8 KTS. HE STATED THAT MAX POWER & RPM WERE OBTAINED. HE NOTED THAT HE OBTAINED 39 INCHES OF MANIFOLD PRESSURE & 2235 RPM AT 100 KTS IAS. REPORTEDLY, THE ACFT ROTATED PROPERLY, BUT BEGAN TO VIBRATE & SHUDDER & WOULD NOT LIFT OFF. THE PLT THEN LOWERED THE NOSE & ACCELERATED TO 110 KTS IAS. HOWEVER, AGAIN, THE ACFT WOULD ONLY VIBRATE & SHUDDER & WOULD NOT LIFT OFF. THE PLT THEN BEGAN ABORTING THE TAKEOFF. THE ACFT WENT OFF THE END OF THE RWY AT 70 TO 80 KTS & BECAME AIRBORNE FOR APRX 75 FT AS IT WENT OVER A DROP OFF IN THE TERRAIN. SUBSEQUENTLY, THE ACFT LANDED IN SOFT SOIL & HIGH GRASS WHERE THE GEAR COLLAPSED. AN INVESTIGATION REVEALED THAT THE TEMP WAS 30 DEG & SNOW WAS FALLING.
