Doesn't apply if you're "Landing in accordance with normal aviation procedures." and that includes private strips. A low level pass or a go around into a private strip is technicaly illegal.
I think that a reasonable case could be made that a low pass may be "necessary" for landing at a private or non-radio site - not least because such a procedure is a required part of the flight test for the EASA Mountain ratings.
Or, put another way, what is "normal" or "necessary" depends not only on the type of aircraft (A380, balloon, glider, or whatever) , but also on the crew, the nature and equipment of the landing site and perhaps a score of other variables.
