The outcome was as good as it could have been. But, frankly, I disagree with him killing the engines and even more with him pumping the starter to synch the props out of the way, especially the last time he did it on the left engine because he was already crossing threshold. He should have been concentrating on the landing and leaving his engines on to facilitate an emergency go-around. I know why he did what he did. He wanted to save the expense of tearing down for inspection both engines. That would have cost him about $30,000 assuming no engine damage was discovered and the parts could be put back together.
Distraction is a major cause of mishaps, especially as a single pilot in a GA aircraft. If he had a co-pilot then I could see him briefing the other pilot to chop power to both engines immediately upon main gear touchdown. But, when you have such a mishap and cannot get the gear down, then you focus on flying a normal approach and landing with a normal touchdown, and all you do different is try to hold the nose gear off the surface as long as possible so it contacts at the lowest ground speed possible.
Insurance takes care of the cost of putting the plane back into service, or at least compensating the pilot for total loss. Their is no aircraft insurance that brings back human life.
