So according to Flyting from the RFM, and lack of any other meaningful response, we still don't know in what conditions, if any, level flight can be maintained in a 350 with a T/R drive failure. Shame and surprising, given the huge number of hours that must have been flown on 350s worldwide. Maybe the reality is such a failure is virtually unheard of, apart from newfie's impressive experience, which was compounded by engine failure. Any further update on likely cause? Fuel cut off lever position might be interesting - to have such little damage after a T/R drive failure the engine must surely have not been delivering power.
