## Discrepancy

JUST AFTER ROTATION GOT HYD CAUTION LIGHT ON AND MAIN PRESS DOWN TO 0 PSI.  HYD QTY DECREASING FOLLOWED QRH.  RETURNED TO DTW.  FOUND RT DOWNLOCK ACTUATOR ROTATING SWIVEL BROKEN.  REMOVED AND REPLACED SWIVEL IAW SAAB MM CHAP 32 AND BLOWN SEPARATION BOLTS WERE REPLACED IAW SAAB MM CHAP 32.  ALL CHECKS GOOD.
