Preparing to Install Main Gear Fairings – 8 hrs

Saturday Feb 1, 2014

This weekend was my first chance try out the jack stands I built to lift the fuselage and take the weight off the landing gear. This is needed to install and align the main gear fairings (pants). I used the engine hoist to lift the engine mount to level the longerons so the aircraft support is on three points. It is quite stable and I don’t have any concerns about the stands tipping over so I can leave the airplane this way for a while.

First thing I needed to do was install the wheel fairing support brackets. I fit these to the wheels a long time ago but I found that I needed to trim down the three tubular spacers about 0.1 inch to get the gap to the bracket set in the .032 -.094 range called for on the drawing. That took a while but I got everything back together again with the brackets installed and ready to receive the fairings.

I dropped a plumb line from the center of the firewall and another from the tie down ring on the tail and snapped a chalk line between them to mark a centerline for the aircraft. Then I measured out about 40.25 inches in tow places and snapped another chalk line parallel to the centerline but passing through the centerline of the tire where it touches the ground. I did this on both sides of the aircraft. These are my lines to which the wheel pants will be aligned.

Back on the nose gear fairing, I mixed up some epoxy with flox and I gooped it up in between the nose gear fairing and the brackets. These brackets don’t sit flush on the fairing surface and the epoxy is to form a shim that makes the connection solid without distorting the fairing. After installing the wheel fairing I checked the alignment and then left it alone for about 3 hours while the epoxy cured. I switched out the clecos after that to make sure I did not epoxy those in place and let it cure another 2-3 hours.

After that I took off the leg fairing and started fitting the hinge that holds the rear edge together. Here you see it drilled and cleco’d to the fairing. I trimmed the hinge to length but I left the hinge pin long for now.
