I launched the 737-900ER for the first time and spotted an issue:
The Aft Emerg. Door (the extra door on the -900ER) does not come down even with the button pressed. What's more awkward is that the window on the door comes off as it should. Which means that the window detaches from the door and rotate downwards but the door itself remains closed.
I checked the aircraft in PlaneMaker and the animation was made. Does anyone know how to troubleshoot the issue?
Thanks in advance!
