I'm tempted to look at the actual hazard rather than what the commodity is called. Airplane house/garage usually means hanger with the associated hazards, but if you just have aluminium tubes with appendages...? Presumably less activity than a typical warehouse, no combustible liquids like in a parking garage and far less transients. Shielding of the floor by the wings but private planes suggests A size aircraft so minimal, and what's the likelihood of a hugely hazardous build-up of debris? I think they may be right. I think it needs questioning but the final say is, as usual, the AHJ. And the usual admonitions to CYA. Defining the hazard is not your call.
