As the chaps say above, if you need to do it then do! When you have a cabin fire etc you might as well chuck the manuals out of the window and get it on the deck, that is the priority...I have done 2, one after engine vibratrion and the other medical emergency. On both occasions there was merely an overweight landing inspection to do which takes a couple of hours tops. (NON EVENT). Its all about priorities guys not manuals and beancounters!!
