What was found
MAINTENANCE FOUND THAT THERE WAS EXCESSIVE TENSION IN THE RELEASE CABLE SYSTEM. SO MUCH TENSION THAT THE CONE RELEASED WITHOUT PULLING THE CABLE. ALSO, THE KEVLAR SLEEVE OVER THE RELEASE CABLE FOR THE TAILCONE WAS WORN OUT OF ALLOWABLE LIMITS. THE CABLE WAS REPLACED AND THE SYSTEM WAS RIGGED TO SPECIFICATIONS. THE RII STEPS WERE COMPLETED AND THE FOLLOW-UP CHECK WAS SUCCESSFUL.
