What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On 05/21/2010, the albany FSDO received notification of an aircraft accident at Chapin Field in Cambridge NY. Inspectors borrell and taylor from the albany FSDO responded to the accident scene. Mr. Stephen clearman, (certificate no. 3317803) is the owner and PIC of the accident aircraft N234JK a Cessna P210N serial no. P21000177, modified in 2004 by STC SA1003NE with the installation of a rolls royce model 250B17F/2 turbine engine. The passenger in the right seat was a CFI Mr. Robert f. brew (certificate no. 3190977) both CFI and PIC were trained by the silver eagle team, o&n aircraft modifications, inc. factoryville, PA. Both PIC and CFI were current and qualified for the type of operation which was being flown. My investigation reveals that the PIC was attempting a short field take-off on a grass runway. The PIC held excessive back pressure once take-off power was applied, and failed to fully correct for the take-off torque produced from the engine. By doing so, the aircraft veered left of center line distracting both CFI and PIC. The aircraft was planned to rotate at 66 knots, but because of the pic's excessive back pressure on the controls, became airborne around 55KNOTS. This caused the aircraft to veer further left due to the relative ineffectiveness of the rudder at the slow airspeed. At this point, the PIC applied full power, in an attempt to fix the situation, but by applying the full power, it caused the aircraft to veer violently left and touch down on the left main gear in a plowed farmers field next to the runway. The plane then bounced and became airborne again. The right main then touched down, and once again, bounce airborne. The PIC at this point closed the throttle, and the plane settled on both main gear, but when the nose touched down, it dug into the earth, causing the airplane to slowly flip and coming to rest upside down.
As the FAA filed it
ON 05/21/2010, THE ALBANY FSDO RECEIVED NOTIFICATION OF AN AIRCRAFT ACCIDENT AT CHAPIN FIELD IN CAMBRIDGE NY. INSPECTORS BORRELL AND TAYLOR FROM THE ALBANY FSDO RESPONDED TO THE ACCIDENT SCENE. MR. STEPHEN CLEARMAN, (CERTIFICATE NO. 3317803) IS THE OWNER AND PIC OF THE ACCIDENT AIRCRAFT N234JK A CESSNA P210N SERIAL NO. P21000177, MODIFIED IN 2004 BY STC SA1003NE WITH THE INSTALLATION OF A ROLLS ROYCE MODEL 250B17F/2 TURBINE ENGINE. THE PASSENGER IN THE RIGHT SEAT WAS A CFI MR. ROBERT F. BREW (CERTIFICATE NO. 3190977) BOTH CFI AND PIC WERE TRAINED BY THE SILVER EAGLE TEAM, O&N AIRCRAFT MODIFICATIONS, INC. FACTORYVILLE, PA. BOTH PIC AND CFI WERE CURRENT AND QUALIFIED FOR THE TYPE OF OPERATION WHICH WAS BEING FLOWN. MY INVESTIGATION REVEALS THAT THE PIC WAS ATTEMPTING A SHORT FIELD TAKE-OFF ON A GRASS RUNWAY. THE PIC HELD EXCESSIVE BACK PRESSURE ONCE TAKE-OFF POWER WAS APPLIED, AND FAILED TO FULLY CORRECT FOR THE TAKE-OFF TORQUE PRODUCED FROM THE ENGINE. BY DOING SO, THE AIRCRAFT VEERED LEFT OF CENTER LINE DISTRACTING BOTH CFI AND PIC. THE AIRCRAFT WAS PLANNED TO ROTATE AT 66 KNOTS, BUT BECAUSE OF THE PIC'S EXCESSIVE BACK PRESSURE ON THE CONTROLS, BECAME AIRBORNE AROUND 55KNOTS. THIS CAUSED THE AIRCRAFT TO VEER FURTHER LEFT DUE TO THE RELATIVE INEFFECTIVENESS OF THE RUDDER AT THE SLOW AIRSPEED. AT THIS POINT, THE PIC APPLIED FULL POWER, IN AN ATTEMPT TO FIX THE SITUATION, BUT BY APPLYING THE FULL POWER, IT CAUSED THE AIRCRAFT TO VEER VIOLENTLY LEFT AND TOUCH DOWN ON THE LEFT MAIN GEAR IN A PLOWED FARMERS FIELD NEXT TO THE RUNWAY. THE PLANE THEN BOUNCED AND BECAME AIRBORNE AGAIN. THE RIGHT MAIN THEN TOUCHED DOWN, AND ONCE AGAIN, BOUNCE AIRBORNE. THE PIC AT THIS POINT CLOSED THE THROTTLE, AND THE PLANE SETTLED ON BOTH MAIN GEAR, BUT WHEN THE NOSE TOUCHED DOWN, IT DUG INTO THE EARTH, CAUSING THE AIRPLANE TO SLOWLY FLIP AND COMING TO REST UPSIDE DOWN.
