When the aircraft's attitude
is nose-high, after the slip into the cross wind on approach must
necessarily be terminated for fear of dragging a wing on the ground,
the pilot has no good means of controlling lateral drift. If the
wheels can be planted on the runway before sufficient lateral velocity
and its inertia mount to unacceptable magnitude, all is well.

Purely sophomoric quip, it strikes me that any crosswind landing
attempt where the crosswind is so strong that the aircraft risks a
wing-strike would already be far beyond the capacity of the rudder to
maintain the slip (and WAY beyond the aircraft's demonstrated X-wind
component).

It is of course always possible that a gusty crosswind might 'send the
plane over the edge' at the worse possible moment... but then I would
question the judgement of the pilot to even think of getting so close
to the ground in a drag-heavy deep slip configuration... The
windshear risk alone would make that a dangerous proposition.

The situation you describe strikes me as being a very clear diversion
scenario. In the absence of that option, my instructor suggested that
(at least in my stout-legged PA-28) in an emergency, during a heavy,
gusty crosswind beyond the aircraft's rudder capacity, your best bet
is simply to go with the "crab-plant' approach, and associated repair
bills.

I in no way vouch for this approach, I'm just relaying what I was told.
