AO, not seen any pics of a Q-A on skis,but others may have...a Q-A has low wings ,engine intakes and props,unlike something like a T-Otter...so landing on skis may throw up a lot of `muck` that may impinge on the engines/props,especially from the nosewheel.....however,a book I have on `bush-pilots` in Can,and Alska shows aircraft operating on skis off mud-flats,tidal beaches, ets...however most were tailwheel,or high-wing.....
