## Discrepancy

THE PITCH SERVO BRIDLE CABLE WAS FOUND TO BE LOOSE AND NOT CONNECTED TO THE CAPSTAN.  IT WAS WOUND BETWEEN THE BOTTOM END OF THE CAPSTAN AND THE CAPSTAN END PLATE WITH THE CLAMP TO THE ELEVATOR CABLE HAVING BEEN SLIDING ON THE ELEVATOR CABLE.  THE ELEVATOR WAS FOUND TO BE FREE TO MOVE NORMALLY IT IS NOT KNOWN HOW THIS MALFUNCTION OCCURRED.  IT IS POSSIBLE THAT THE BRIDLE CABLE CLAMP WAS NOT SUFFICIENTLY TIGHT ALLOWING THE BRIDLE CABLE TO BECOME SLACK AND COMING LOOSE IN THE CAPSTAN.  (K)
