2 cents
Really sad to hear about this accident, the NTS system is really easy to check on that type engine, but I feel that a non professional pilot really needs to stick to something like a King Air or 690, both do much better with a caged engine.
I think the MU2 in this accident was one that was manufactured to produce full power on the day it was new, no reserves built it as in later models, no part time pilot should be operating this type of equipment.
