Hi there, First of all I just wanted to congratulate the developers of the TBM 900 for an incredible job, it's a stunning machine. Nevertheless I am having a little issue with the plane. After the first flight on a new airframe and having shut down the airplane, when I get back to it and try an engine start (all following manuals), strait after ignition and moving throttle lever on low idle the engine makes a horrible rattling/grinding noise. Changing all engine components doesn't solve the issue. Engine start through tutorial doesn't present the same issue and the startup after that works fine. After a restart the issue presents itself again though. I hope you can help.
