Initial Acceleration Sqeal
Hey everybody,
My 2021 PB, just started having this grind/squeal sound upon accelerating after having sat parked for any amount of time. It happens on initial acceleration, the one time and doesn’t happen again until it sits parked. I’m attaching a video of the sound, to see if anyone can help me diagnose what is causing this.
It did seem to start shortly after having had new tires put on. Not sure if that’s just a coincidence or not.

You may have trouble getting many of us to open that file, try sticking it on You Tube, safer for all concerned.
BTW, P51D is a gorgeous airplane.
