The right over-wing slide carrier deployed in flight, allowing the slide to unravel possibly as a result of the crank handle with a reduced breakout friction progressively moving, over an indeterminate period of time, to an unsafe position. A contributory factor was possibly the loose number 6 screw jack in the flap system which resulted in vibration in the area of the crank handle. The insecurity of the lever went undetected whilst the maintenance panel was open due to the lack of alignment marks and unfamiliarity of the observer(s) with how the crank handle should look when correctly positioned. SB 757‑25-0298 addresses locking of the compartment door and provides revised and clearer alignment placards for the lever.
