This just happened in my neck of the woods.
Gotta give the PIC some kudos.

It's good to see another emergency that only resulted in some bent
aluminum.

I have never flown retractables and don't completely understand the
systems, would it be strange for two out of three wheels to not
extend. Would it be an electrical, hydraulic or mechanical failure
that would most likely create such a 2 out of 3 scenario?
