It's pretty obvious he was having enough difficulties just keeping control of the airplane. In that case not worrying about shutting down the engines and feathering the props after touchdown is a good move.

Re: Coulda feathered the props
Worst thing you can do is feather the props in this situation. Rotating in fine pitch the tips just bend back as the props hit. Stopped and feathered the whole width of the blade is resisting the bending forces. This is a great way to break the crank and bend the engine mounts or warp the firewall.
All you should do is pull the mixtures to idle cutoff in the flare.

That seems pretty sensible to me..
just try dragging a metal ruler along the floor in the two orientations and the one that apples the most force on your hand will be pretty obvious.

If you pull the mixtures in the flare, the flare is going to stop being a flare pretty quick. Remember what an unfeathered prop does for your aerodynamics? X2?
Conduct a 'normal' landing first, then worry about shutting stuff off.

Re: Coulda feathered the props
Good point I was think more about an all wheels up landing. In this case you should obviously wait until the mains have touched before pulling the mixtures to ICO. I stand by my contention that feathering the props is a bad ideaxsbank wrote:If you pull the mixtures in the flare, the flare is going to stop being a flare pretty quick.
