LUSCOMBE 8A
THE ACFT WAS TAKING OFF ON A HARD PACKED, GRASSY AREA BESIDE A PAVED RWY WITH A 12 KT HEADWIND. AFTER THE TAIL WAS RAISED, AND AT A POINT 900 FT FROM THE BEGINNING OF THE ROLL, THE ACFT SUDDENLY NOSED OVER. EXAMINATION OF THE BROKEN RIGHT MAIN LANDING GEAR LEG REVEALED EVIDENCE OF A PRE-EXISTING CRACK AROUND 3/4 OF THE LEG AND A FRESH BREAK ON THE REMAINING 1/4 OF THE LEG. ACCORDING TO A FAA OPS INSP WHO PARTICIPATED IN THE INVESTIGATION, COMPLETE FRACTURE OF THE LEG 'RESULTED IN THE SHAFT EXTENDING. THIS EXTENSION CAUSED THE MECHANICAL BRAKES TO BE APPLIED TO THE RIGHT WHEEL, LOCKING UP THE BRAKE AND FLIPPING THE A/C ON ITS BACK.'
