With one person on board, anything over 65 knots will result in quite a prolonged float even with full flaps, since it is a slippery aircraft with all three wheels spatted. At max weight, a 70 knot approach is better. Allowing the airspeed to decay too much can result in an embarrassingly firm arrival, although its greater elevator authority at low speed than its sister, the AA5 Traveller, does allow such arrivals to be on the main wheels. Its crosswind capabilities are quite acceptable. The book value is 15 knots, although the rudder authority feels as if it would be safe to land above this.
Great care is needed to keep the nose wheel off the ground when landing, since it's easily damaged.
This is hardly a drawback, though, just standard good practice. Personally, I think it's a lovely aircraft. Much nicer handling than the Cessnas and Pipers I've flown, and still great for touring, with none of the admin and expense of variable pitch props and retractable gear.
