## Discrepancy

(CAN) ELECTRIC TRIM (ELEVATOR) DRIVE SHAFT SHEARED. THIS CAUSED ONE CAPSTAND TO OPERATE AND THE OTHER TO MOVE FREELY ON ITS OWN. THIS MOVEMENT CAUSED THE BRIDAL CABLES TO UNWIND AND CREATE RESTRICTION. THE TRIM WAS RESTRICTED FROM GOING NOSE DOWN. MANUAL MOVEMENT OF THE TRIM WAS ALSO RESTRICTED.
