It was very interesting watching Jeff, our interior expert, do this work.

The interior shapes and surfaces of the aircraft are a very difficult problem, with many compound curves, strange angles abrupt changes in direction, moving parts, and the need for removable parts and access for inspection.

These six materials were involved, from left to right:

  • Low density foam backing
  • High density closed cell foam (landau foam)
  • Heavy black cardboard, for patterns and inserts
  • Grey vinyl
  • Perforated suede headliner
  • Grey marine-grade carpet

The center keel was one of the more interesting challenges. After applying landau foam to the keel with contact cement, the vinyl was stretched over the foam, formed with a heat gun, and glued down.

Inspection covers were covered with vinyl and then re-installed. You can see one of these just to the left below the speaker grille.

Most aircraft interiors are pretty stark and/or in bad taste. The worst I ever saw was in a corporate jet that looked like the reception area of a cheap massage parlor.

We wanted a more finished, car-like feeling, and Jeff was able to do that for us.

Here is the recess at the wing root, which is lined with perforated suede and equipped with a foam arm rest.

Here is the overhead duct with the reading lights and air vents re-installed.

The perforated suede headliner came out very well. We expect that the aircraft interior will be very quiet with all the foam that was used under the upholstery.

We were very glad we used push-on connectors on all of the electrical items!

In some places, the complex compound curves were too extreme to form the vinyl, and Jeff had to sew special fitted pieces.

The overhead panel area was one such place.  You can see one of the seams in the right upper corner of the picture.

There is a saying that, "The devil is in the details." Those particular devils continue to visit us on a daily basis.

We had to make a custom bracket for the fire extinguisher. It was driving us crazy because it wasn't parallel to its mounting bracket.

Ok, Ok!  I know.  It's really "anal."  We can't help it!

We decided that the aluminum position lights looked tacky, so we took them off and painted them. Looks much better, doesn't it?

Many items had to be painted individually. The front landing gear fork was removed, cleaned, sanded, filled, primed and painted two times before we got it the way we wanted it. Scott Swing helped us with this; it was quite a job.

Next session, we will be taking on another small army of "detail devils."  I hear them hissing and laughing in the dark corners of the hangar.
