## Discrepancy

MAIN DOOR: MAIN CABIN DOOR DOES NOT FREE FALL.  DISENGAGED THE CABIN DOOR LIFT MOTOR AND OPERATE DOOR MANUALLY. OPS CHECK GOOD NO ISSUE WITH DOOR OPEN/CLOSE MECHANISM. ENGAGED CABIN DOOR MOTOR AND OPERATE DOOR, DOOR REQUIRES A LIGHT FORCE TO OPEN. PER CE-680A AMM 52-15-00 3-A (2) 'WHEN THE CABIN DOOR IS OPENED THE LIFT MOTOR APPLIES BRAKING THAT PREVENTS THE DOOR FROM OPENING TOO RAPIDLY AND CAUSING INJURY OR DAMAGE TO THE AIRPLANE."
