I suppose he means something like the Emirates A340 ferry flight from Melbourne to Toulouse at 10,000ft after that nasty tail strike... I hardly doubt there are many written procedures for this, I can't think of much that has to be taken care off - I guess the airframe is under a bit less tension (like a balloon with too little air) so possibly you have to limit loads a bit?!? Total stab in the dark, I'm probably wrong...
