Narrative:

Found aircraft depowered since the night before with only 1 set of chocks on the nose gear. There was no hydraulic pressure applied and the parking brake message was no longer posted. The aircraft was parked faced down hill. This situation occurs regularly where they pull overnight triple chocks prior to aircraft being powered up. It is not uncommon to find a set of nose gear chocks pushed out of the way as the airplane starts to creep forward down the hill. With the equipment often already placed around the aircraft the aircraft could strike it if it begins to roll too far.get the ground handling manual modified to change procedures to not remove triple chocks until power is established on the aircraft and hydraulic pressure is restored to ensure the parking brake is actively holding the aircraft in position.

Title: A CRJ-200 Captain reported repeated incidents of finding aircraft prepped by ground crews for first flights of the day not being properly chocked prior to hydraulic pressure being applied to the brakes.
