## Analysis

THE PLT HAD BEEN OBSERVED TO MAKE TAKEOFFS USING MAXIMUM UP ELEVATOR FOR LIFTOFF. THE ELEVATOR WAS FOUND IN A NINETEEN DEGREE UP POSITION AND BOTH THE LEFT HORIZONTAL STABILIZER AND ELEVATOR WERE BENT UPWARD AT THE TIP. THE DOWN ELEVATOR CLEVIS WAS OBSERVED JAMMED AGAINST A SECTION OF BULKHEAD PREVENTING THE PILOT FROM UTILIZING NOSE DOWN ELEVATOR PRIOR TO IMPACT. THE ACFT STALLED AND FELL INTO A NOSE DOWN LEFT SPIN, WHICH CONTINUED TO IMPACT.
