(-23) ON JULY 31, 2004, AT APPROXIMATELY 0950 LOCAL TIME, MR. STROBEL AND HIS STUDENT DEPARTED FROM CUSTER, SD (CUT) ON RWY 8. THE WEATHER WAS CLEAR, THE WIND WAS FROM 250 DEGREES AT 9 KNOTS, THE TEMP WAS 26 CELSIUS AND THE ALTIMETER WAS 3004. THE INSTRUCTOR TOOK OFF WITH A TAILWIND WITH DENSITY ALTITUDE OF APPROX. 8000'. MR. STROBEL CLAIMED THAT AT TWO THIRDS DOWN THE RUNWAY HE DID NOT REACH HIS GOAL OF 90 MPH AND ELECTED TO ABORT THE TAKE OFF. AT THE LAST THIRD OF THE RUNWAY BY THE INTERSECTION THERE WERE SKID MARKS. THE AIRCRAFT CONTINUED TO SKID OFF OF THE END OF THE RUNWAY AND CAME TO REST APPROXIMATELY 80 YARDS OFF OF THE END OF THE RWY. APPROXIMATELY 100 YARDS PRIOR TO LEAVING THE RWY, THERE WERE TIRE AND WHEEL MARKINGS ON THE RWY INDICATING THE TIRES WERE FLAT AND THE AIRCRAFT RIMS WERE CONTACTING THE RWY. IT APPEARED THE GEAR SCISSORS BROKE ON BOTH MAIN GEAR AFTER THE AIRCRAFT DEPARTED THE RUNWAY CAUSING THE GEAR TO DRAG SIDEWAYS. THERE WERE NO REPORTED INJURIES. THE AIRCRAFT HAD SUBSTANTIAL DAMAGE TO THE LANDING GEAR, THE RIGHT WING, BOTTOM OF THE RIGHT AND LEFT WING NEAR THE GEAR ATTACH POINT AND SKIN WRINKLING FROM THE GEAR ATTACH AREA TO THE FUSELAGE. THERE IS ALSO POSSIBLE WING SPAR DAMAGE TO THE ACFT.
