Continuous whining sound

[Lighttrail]

I am experiencing a continuous whining sound after the plane is shut off. It gets louder as you open the door, which makes me think that it is supposed to be a part of the engine sound. The sound just keeps looping and I can't figure out what is causing it. If I close X-Plane and come back in, the sound is gone. I'm using 11.50b16.

Which plane is it NA or TN version. Can you hear the sound in one particular location? Thanks. I will listen upon engine shut off and try to replicate this.

It’s the TN version. I can hear it from within the aircraft but not when I change the view to outside. The sound is present with different views inside the plane but gets much louder when a door is opened. I never hear it before starting, only after shutting down.

Fixed. New datarefs towards the end of the development cycle that I did not properly tie in to FMOD.
