Narrative:
After takeoff landing gear handle was raised on schedule; but after the main mounts indicated up and locked the nose gear indicated an amber hash pattern indicating according to the emergency/abnormal. Preliminary inspection revealed the right/H nose gear door was damaged by the nose gear during gear retraction. After further investigation; it appears the right/H nose gear door was not in the over-center position (normal position) up against the open stops and caused the nose gear door rollers on the right side to strike the door bending the door edge during the retract sequence.I believe this is a design flaw and should be addressed by the oem. Also train pilots to verify doors are in the fully open position and up against the stops. As maintenance vendor; some kind of verification that door is in the proper position during post maintenance.
