Pprune time.....
I'm guessing one of the oleo's / skids broke and he couldn't do a level landing.
Either he ran out of fuel or tried to land upright but failed. Cab rolled, blades hit and - game over.
Several options available:
Land with duff skid up slope and shut throtors down slowly.
Use sandbags under the duff skids.
Attempt to fix duff skids whilst in the hover.
Extricate any surplus crew to minimise injured parties, prior to landing.
What else could have gone wrong - yet gave the pilot time to hover and wait for assistance?
Sad.
