One occurrence I've noticed with some of the owner/single pilot jet accidents, is the presence of a non-pilot friend in the right seat, that the pilot is trying to impress or educate. In this case the passenger had been given reign over the radios, and had various ATIS and AWOS competing with ATC for attention. You would think a Phenom would have XM weather and textual METARS.
The worst example was a Premier that went down in Indiana, where the pilot was letting the passenger adjust power during a descent. The pax ended up bringing the levers back into idle cut-off, and the pilot could only get one restarted. It ended with a poorly flown single engine approach.
