Those of us that travel much have all thought about what we need to fix a flat away from home. Of course we all carry the requisite tools, but lifting the airplane is a tricky part. This is my lift solution for those emergency cases. It isn't appropriate for normal everyday maintenance, and I still use a wing jack in the hangar. There are a lot of ways to skin this cat. I think I've seen most of them, but this is what gives me some piece of mind when far from home at that desolate fuel stop that had the cheapest fuel, but looks like you just landed on the face of the moon without a soul in sight.
It consists of a lift shaft, a steel bracket bolted to U-403 via some new CNC solid aluminum spacers, and a steel foot with a thrust bearing in the bottom. The bracket is plugged, top and bottom, to keep terrestrial gunk out while hopefully never in use.
We've made a number of these to spread around and have a few left from the last batch if you're interested here
. This only works on round gear legs that use Vans U-403 brake flange, which means 4, 6/6A, 7/7A, 8A, and 9/9A, refer to Vans drawing C2. Pictured is for tricycle gear and we have a different bracket for conventional gear.
