Narrative:

Accelerated to 40-45 KTS, strong yaw to the right. Applied maximum brake, maximum reverse, maximum nosewheel to the left. It felt like left engine still producing forward thrust. It took over 30 yards to stop the aircraft. 5 mph hit the snow bank and some boulder rocks, folded the nose gear, impacted the nose and bottom of aircraft wingtip struck the ground. Something happened -- either left engine linkage system or lost right engine? Very eerie feeling! Automatic power reserves were selected for takeoff. Callback conversation with reporter revealed the following information: reporter stated that he suspects that the throttle linkage was responsible for the loss of control since the left engine had just been changed the day before and he noticed that the power levers were offset and not even when matching the same power output on the engines. There were no other problems found during examination of the propellers or engines. The private runway was a snow covered gravel which he found did not provide any traction for the nosewheel steering or braking. They had only gone a short distance and at 5 KTS when all power was taken off and reverse applied. There was no time to use differential reverse since the runway is so narrow, and they were heading to the runway side, snow bank. All available power was used in an effort to stop the aircraft.

Title: FLC OF A TURBOPROP CASA 212-200 LOST CTL OF THE ACFT RIGHT AFTER APPLYING TKOF PWR DUE TO A SEVERE R DRIFT RESULTING IN THE ACFT GOING OFF THE SIDE OF THE RWY INTO A SNOW BANK. THE NOSE GEAR WAS SHEARED OFF BY A ROCK AND THE BOTTOM OF THE FUSELAGE, AND THE R WINGTIP DAMAGED.

Narrative: ACCELERATED TO 40-45 KTS, STRONG YAW TO THE R. APPLIED MAX BRAKE, MAX REVERSE, MAX NOSEWHEEL TO THE L. IT FELT LIKE L ENG STILL PRODUCING FORWARD THRUST. IT TOOK OVER 30 YARDS TO STOP THE ACFT. 5 MPH HIT THE SNOW BANK AND SOME BOULDER ROCKS, FOLDED THE NOSE GEAR, IMPACTED THE NOSE AND BOTTOM OF ACFT WINGTIP STRUCK THE GND. SOMETHING HAPPENED -- EITHER L ENG LINKAGE SYS OR LOST R ENG? VERY EERIE FEELING! AUTOMATIC PWR RESERVES WERE SELECTED FOR TKOF. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT HE SUSPECTS THAT THE THROTTLE LINKAGE WAS RESPONSIBLE FOR THE LOSS OF CTL SINCE THE L ENG HAD JUST BEEN CHANGED THE DAY BEFORE AND HE NOTICED THAT THE PWR LEVERS WERE OFFSET AND NOT EVEN WHEN MATCHING THE SAME PWR OUTPUT ON THE ENGS. THERE WERE NO OTHER PROBS FOUND DURING EXAMINATION OF THE PROPS OR ENGS. THE PVT RWY WAS A SNOW COVERED GRAVEL WHICH HE FOUND DID NOT PROVIDE ANY TRACTION FOR THE NOSEWHEEL STEERING OR BRAKING. THEY HAD ONLY GONE A SHORT DISTANCE AND AT 5 KTS WHEN ALL PWR WAS TAKEN OFF AND REVERSE APPLIED. THERE WAS NO TIME TO USE DIFFERENTIAL REVERSE SINCE THE RWY IS SO NARROW, AND THEY WERE HDG TO THE RWY SIDE, SNOW BANK. ALL AVAILABLE PWR WAS USED IN AN EFFORT TO STOP THE ACFT.
