July 11, 2009 - Gear Fairings & Wheel Pants |
||||||
I had most of my test period hours flown off, so I stopped flying and shifted my effort to getting the gear fairings and wheel pants on. I had done a little work on the gear fairings previously. The next step was to match-drill and rivet the piano hinge to the fairings. No big deal. I did one side at a time per the instructions. | ||||||
All
done.
|
||||||
I cut notches out of the upper gear fairings per the instructions. These enable hose clamps to secure the gear fairing to the gear. | ||||||
I match-drilled the wheel pants
together.
|
||||||
In order to properly align the gear fairings and wheel pants, the instructions call for jacking the aircraft to get the weight off the gear. I decided to do it by using the engine hoist. It worked pretty well; however, later I read a post by a DAR saying this was not a good idea. The engine isn't designed to take the weight of the entire aircraft. So don't do like I did. You can still use the engine hoist -- just use straps around the engine mount. | ||||||
I only jacked the hoist until the main gear just came off the floor. The instructions also called for lifting the tail into the flight position. I discovered that with the front-end lifted, I couldn't lift the tail end. Lesson learned -- lift the tail first, then the front end. |
||||||
The gear and wheel moves substantially when the weight is off. | ||||||
I was surprised with how much
trimming I had to do to the wheel pants to get them to fit.
Here is a picture of the notice cut out in the aft wheel pant to get it to
fit around the gear strut.
|
||||||
I put a 1 inch block on top of the wheel to get the required spacing between wheel and wheel pant. | ||||||
I match-drilled the wheel pant to the
outboard bracket.
|
||||||
During my test flights, I started getting a little prop grease thrown on the right front of the canopy. At first I thought it was coming from these two screws on the prop hub. But tightening them didn't make any difference. | ||||||
A suggestion on the Vans Air Force forums finally solved the problem. I found the leak along the prop hub seam. The solution was to tighten the prop hub nuts. | ||||||
