Wheel pant repair-enlarged (for RV).

 A neighbor brought a wheel pant over after running over something, probably a chunk of asphalt.  Initially he just wanted it repaired, but then a friend of his suggested that since he had an oversized tire, enlarging the pant some would be great.



I sanded the paint off the damaged area and applied some UNI on the outside to get the original shape restored.   After it cured, the Fein tool cut multiple slits longitudinally and one laterally in the glass to increase the clearance where the tire rubs.


Cardboard and hot glue held the "fingers" in their new position.



The wheel pant was turned over, and was held nicely by an empty case of Shiner with a couple pieces of box tape on the flaps to keep the pant secure.  One layer of BID covered the slits on the inside of the pant.  After it cured, I decided that the raised hump needed to be a bit rounder on the sides, making the enlargement less noticeable, so I added two more slits on the sides and curved the bottom cut a little, which added more radius to the enlargement.  Additional BID strips were applied on the inside of the pant to the last two cuts.

Isopropyl alcohol removed the hot glue.  Sanding with a small DA sander and starting with 60 grit, the edges of the slits were rounded.   Then a mix of wet micro balloons and a little flox was buttered into the gaps between the slots.  

After the micro/flox cured, it was sanded down and checked for bumps.   It felt pretty smooth.  The neighbor did a test fit and will do some flying to make sure it's okay before taking it to the painter.

Update 10/15/2022

 

2nd to last flight on 10/13/2022 had the fuel pressure spike for a bit.  I pulled the power back (regulator is modulated by manifold pressure) and it returned to normal.
Was okay on the return flight.   I'd recently replaced a couple $ensors since Dynon issued a technical bulletin on them (pre 2018 Kavlico) leaking.
Having all this EFIS data is a mixed blessing.  I think the fuel flow data is reading higher than it should but will need to dial that in after some longer flights.

This flight, I'd moved the CG aft 1", installed wheel pants and unexpectedly had gusting x-winds.  The METAR said calm, the wind sock disagreed and on one of my touch and go-arounds, thought maybe my wheel pants were causing problems.   The further aft CG had the nose quite a bit lighter and touch down handling in the x-wind got my attention.   After landing, the wheel pants and tires look okay (were still there/not rubbing/smoking).   I got some fuel, moved the ballast back to mid-CG and headed home.   No pressure glitches on that flight.   I've changed oil again  and am running the XC oil now.  Filter pleats look good.  Also replaced one of the AN8 466 oil hoses due to tiny leaks at both ends.    

Trying to get fuel data from Dynon Skyview into the Avidyne IFD540 if possible.  Emailed Dynon support for help and been RTFM'ing.

Not sure why but seems like if the GoPro is recording, my landings are better.  :-)
