ON FEBRUARY 17, 2010 AT APPROXIMATELY 2:24 P.M. PACIFIC STANDARD TIME, ATP RATED PILOT ^PRIVACY DATA OMITTED^, WAS ATTEMPTING TO TAKEOFF A CM-170 FOUGA MAGISTER TURBOJET AIRCRAFT IDENTIFIED AS N6222N FROM (IPL) IMPERIAL COUNTY AIRPORT IN CALIFORNIA. THE WEATHER WAS VFR AND REPORTED TO BE CLEAR, VISIBILITY MORE THAN 10 MILES, WINDS FROM 050 DEGREES AT 5 TO 10 MPH WITH THE TEMPERATURE AT 68 DEGREES FAHRENHEIT.^PRIVACY DATA OMITTED^ ATTEMPTED THE TAKEOFF FROM RUNWAY 32. SHORTLY AFTER LIFT OFF THE PILOT LOST DIRECTIONAL CONTROL, STALLED AND SETTLED HARD BACK ONTO THE RUNWAY. THE AIRPLANE SLID SIDEWAYS AND CAME TO REST OFF THE SIDE OF THE RUNWAY. THE AIRCRAFT WAS SUBSTANTIALLY DAMAGED. THERE WAS NO FIRE. THE PILOT SUSTAINED A BACK ACHE BUT HAD NO OTHER INJURIES. THE RUNWAY SUFFERED RUTS AND GOUGES AS A RESULT OF THE LANDING GEAR SHEARING OFF. AT LEAST ONE RUNWAY EDGE LIGHT WAS DAMAGED.ON MARCH 8, 2010, DURING OUR POST ACCIDENT INTERVIEW TOGETHER AT THE SAN DIEGO FSDO OFFICE, ^PRIVACY DATA OMITTED^ SUBMITTED THE FOLLOWING WRITTEN REPORT:"AFTER RE-FUELING AT IPL, EN ROUTE TO SDM (BROWNFIELD) AND A CLOSE WALK-AROUND INSPECTION I TAXIED OUT AFTER 2 NORMAL STARTS. I ANNOUNCED MY TAXI OUT ON FSS FREQ. 122.7. I PERFORMED THE POST START AND PRE-TAKE OFF CHECK LISTS ON MY KNEE CLIPBOARD. EVERYTHING CHECKED OUT EXCELLENT. I TOOK THE FAVORED RUNWAY (32) DUE TO ITS LENGTH AND ROUTINE INSPECTIONS BEING MADE ON 8/26. TAKE OFF POWER YIELDED A SLIGHTLY HIGHER EGT ON THE LEFT ENGINE (650C). THE RIGHT ENGINE SHOWED 600C. THE LEFT ENGINE WAS PULLED BACK VERY SLIGHTLY TO PROVIDE A LITTLE MORE MARGIN WITH THE MAX EGT (675C). THE ACCELERATION INITIALLY WAS NORMAL WITH A LITTLE RIGHT RUDDER TO MAINTAIN THE CENTERLINE. THE FORWARD PRESSURE ON THE STICK WAS RELEASED A BIT TO REDUCE THE VIBRATION FROM THE NOSE WHEEL. THIS VIBRATION IS DUE TO THE HARD NOSE WHEEL TIRE AND THE SURFACE OF THE ASPHALT. THE NOSE CAME UP A BIT TOO HIGH AND THE STICK WAS MOVED FORWARD SUFFICIENTLY TO MAINTAIN THE NOSE WHEEL JUST ABOVE THE RUNWAY SURFACE. AT 100 KNOTS AND ACCELERATING, ALBEIT A LITTLE SLOWER THAN NORMAL, THE AIRCRAFT LIFTED OFF AND I KEPT IT IN GROUND EFFECT TO CONTINUE ACCELERATING TO 140 KNOTS. HOWEVER THE AIRCRAFT PITCHED UP, ROLLED AND YAWED TO THE RIGHT. MY CONTROL INPUTS HAD NO EFFECT AND THE AIRCRAFT STRUCK THE GROUND FROM ABOUT 10 FEET TRAVELING DIAGONALLY TO THE LEFT BUT WITH THE NOSE POINTED TO THE RIGHT. THE LANDING GEAR BROKE OFF. I PULLED THE ENGINES TO IDLE AND THEN SHUT THEM AND THE ELECTRICAL SYSTEMS DOWN. I EXCITED THE AIRCRAFT AND THE FIRE FIGHTERS CAME AND STARTED COVERING EVERYTHING IN FOAM EVEN THOUGH THERE WAS NO INDICATION OF FIRE. 20 MINUTES LATER THEY COVERED EVERYTHING IN FOAM AGAIN."INSPECTOR SUMMARY - THE FIRST RESPONDERS TO THE CRASH SIGHT WERE THE AIRPORT FIREMEN. AS THEY CAME UP TO THE AIRCRAFT WITH THEIR FIRE TRUCK, THEY HEARD THE ENGINES RUNNING AT IDLE AND ASKED THE PILOT TO TURN THEM OFF. THE PILOT STATED "I DON'T KNOW HOW." A MECHANIC SAW THE TAKEOFF ATTEMPT AND WAS THE NEXT PERSON TO RESPOND TO THE CRASH SIGHT. THE FIREMAN ASKED THE MECHANIC TO ASSIST THEM IN SHUTTING DOWN THE ENGINES. THE MECHANIC ASKED THE PILOT TO SECURE THE ENGINES AND AGAIN THE PILOT RESPONDED, "I DON'T KNOW HOW." THE MECHANIC WAS THEN ABLE TO REACH INTO THE COCKPIT AND SECURE THE ENGINES. THE FIRE DEPARTMENT SHOT FOAM INTO BOTH ENGINES AND OVER THE ENTIRE CRASH SIGHT BECAUSE THERE WAS JET FUEL LEAKING ALL AROUND THE SCENE. AN FAA INSPECTOR WAS IN THE AREA AND WAS ABLE TO ARRIVE AT THE SCENE WITHIN ABOUT 20 MINUTES AFTER THE CRASH. THE MECHANIC WHO SECURED THE ENGINES TOLD THE INSPECTOR THAT HE VIEWED THE TAKEOFF ATTEMPT AND STATED THAT ALL LOOKED NORMAL EXCEPT THAT THE AIRCRAFT PITCHED UP UNUSUALLY HIGH RIGHT AFTER LIFT OFF. HE SIMULATED WITH HIS HAND A NOSE UP DECK ANGLE OF BETWEEN 50 TO 60 DEGREES. THE WITNESS THEN SAW THE AIRPLANE FLOP BACK DOWN HARD ONTO THE RUNWAY AND SKID OFF TO THE SIDE.
