What was found

THE INCIDENT OCCURRED ON TAKEOFF ROLL, FORWARD PRESSURE WAS APPLIED TO BRING THE TAIL UP, AT THAT POINT THE CONTROL CABLE BROKE. FURTHER INSPECTION SHOWED THAT THE OTHER CONTROL CABLE WAS 50 PERCENT WORN. IT APPEARED THAT THE PULLEYS COULD BE CAUSING THE PROBLEM THROUGH MISALIGNMENT.
