Which direction do you turn the GSD handle to open it on the CRJ 900?

• A. Clockwise
• B. Counterclockwise
• C. Upward
• D. Downward

Answer: (B)

Turning the GSD handle counterclockwise unlocks the latch by rotating a cam out of engagement. The Ground Service Door on the CRJ 900 uses a rotary latch that releases only when moved in that direction, so turning clockwise would move the latch the wrong way and keep the door secured. This opposite direction design helps ensure the door isn’t opened accidentally. Once the latch is released, you can swing the door outward for access. Always verify the area is clear before opening.
