Narrative:THE AIRPLANE WAS OBSERVED ENTERING AN AEROBATIC MANEUVER SIMILAR TO A TAIL SLIDE. DURING THE MANEUVERING, AN IN-FLIGHT BREAKUP OF THE AIRPLANE OCCURRED. PIECES OF THE AIRPLANE WERE FOUND OVER AN 1800' AREA. AN EXAM OF THE WRECKAGE REVEALED THAT THE CANOPY HAD SHATTERED; THE RIGHT HORIZONTAL STABILIZER, RIGHT ELEVATOR, LEFT AILERON, CANOPY FRAME & PASSENGER'S BODY HAD SEPARATED FROM THE MAIN WRECKAGE. THERE WAS EVIDENCE OF DOWNWARD DEFORMATION ON THE SEPARATED STABILIZER & ELEVATOR. ALSO, EVIDENCE OF A PREEXISTING CRACK WAS FOUND IN THE CANOPY LATCH MECHANISM, BUT THE INVESTIGATION DID NOT DETERMINE WHETHER THE LATCH HAD FAILED BEFORE OR AFTER THE IN-FLIGHT BREAKUP HAD BEGUN. THE AIRPLANE KIT MANUFACTURER DISCOURAGED TAIL SLIDES. CAUSE: THE PILOT'S PERFORMANCE OF A MANEUVER THAT EXCEEDED THE DESIGN STRESS LIMITS OF THE AIRPLANE.
