Leg Fairings Aligned – 9 hrs

Sunday Feb 16, 2014

The gear leg fairings need to be aligned to the nominal airflow when the aircraft weight is off the landing gear. So while the wheels were off the ground I aligned the fairings using the method described in the manual. I hung a plumb bob from the aft edge of the fairing and measured the distances of that point vertically from the floor and out from the centerline. In this photo you can see the plumb bob marking the distance out from the centerline.

Then I set up a stool to establish a point the same distance up off the floor and out from the centerline under the horizontal stabilizer. I strung a piece of string from the stool to and around the fairing at the aforementioned point and pulled it tight. This represents the nominal air flow direction. I then adjusted the fairing until the aft edge bisected the two legs of the string and then tightened the hose clamp that secures the fairing to the leg. It took longer to set this up than it did to adjust the fairing.

After finishing the left main gear fairing alignment I set up to do the right leg but I realized I still needed to install the hinge for that fairing so I did that before I stopped working on Saturday for the night.

In the morning I installed the right leg fairing and aligned it to the air stream in the same way I did the left leg fairing. After that I realized I didn’t really need the airplane up off the ground on jacks any longer so I lowered it down and got the jack stands out of the way. I’m glad to have that done.

For a small diversion I decided to install the seat belts next. I have the Crow harnesses with camloc releases in black with black anodized hardware. Denise picked out the color. I like it because it accents the black instruments on the panel and the stick grips.
