First of all, the parking brakes. They work like on the real aircraft. You need to pressurize the brakes first. Apply brakes normally with pedals or a key stroke. Please note. When I say apply brakes, I do not mean apply parking brakes. Apply BRAKES, then apply parking brakes. The parking brakes hold the brake pressure.
I'll address one thing you said in your post at x-plane.org. We ask everyone to please not compare payware aircraft with other payware aircraft. All payware is created differently, and therefore operates differently when other plugins are thrown into the mix.
As for your other issues. Make sure you do not have failures enabled in the X-Plane menu.
Before loading it again at the airport of your choice, try loading it at a default airport with minimal scenery. A good airport we use for testing is SCIP. Give that a try and post back results. Also, if it crashes again, please post your log.txt. Not your TBM900_log.txt
