I'm planning on finding a shop to refurbish my 1977 Cessna 340. I like the work AirMod does because they will treat corrosion while redoing the interior if they find it. Unfortunately they have a multi-year waiting list so they are out of the question.

Has anyone found a shop that treats corrosion when they redo the interior of older airplanes?

Thanks.

Not removing corrosion but interior shops using the wrong glue has caused a LOT of corrosion on the Cessna airframes that come in to the shop here.

I have seen a 182 with holes in the door frame area bottoms. P210s and Cardinals with the spar carry thru corrosion where glue was brushed on and others with door post issues etc. The black CAT hoses are really bad for causing corrosion.

I believe a lot of it is from interior shops using hardware store Contact cement instead of 1300L. The hardware store type must be more acidic.

Cleaning corrosion from the interior structure can be a real task. Especially if pressurized with sealants to deal with. The wrong person getting in there with a steel scraper or wheel could destroy the airplane. If Cessna primed the airframe they primed over assembled structure and it tends to peel off. Piper hot dipped the parts in Zinc Chromate before riveting on their twins so it is less of an issue. Painting over the peeling Cessna primer won't last. Floor boards and under floor are also susceptible. Spilled drinks on seat rails or moisture from wet things.

We have tried CORBAN clear corrosion inhibiting spray. It seems to be working ok if you can get things cleaned up first.

I have seen some interiors lately where the seat frames were all painted before upholstery was installed. The trouble was they painted over the oil, grease, old paint on the frames without stripping them first and did not use primer. So it starts to peel and chip soon after but the only fix is to remove the upholstery completely and start over.

Stick on Window tint film to hide crazed plexiglass windows on pressurized airplanes is also a new trick. Real fun with new paint to have to go back and replace windows.

Make sure the shop checks if the fuselage lines for the engine gauges are corroded if installed. Pinhole Fuel pressure or oil leak is not fun. Manifold leak can be hard to find.

For cleaning, dry ice blasting and a vacuum would be my choice .

For insulation

Ensolite foam and red 3m high temp Velcro works best

Apply 3m lock Velcro to smooth side of Ensolite

Opposite side of 3m to airframe

Easy to remove and no adhesive required

This is the method on all Columbia aircraft, we die cut Ensolite in seconds with our atom clicker press .

I contacted AirMod twice, once to do the Baron interior and once to do the interior in my 150. Both times they blew me off saying they are too busy. They also refuse to do small jobs. As far as I am concerned their attitude sucks and I would not use them if they were free. A good custom car interior shop can do quite a bit and interior corrosion can be addressed by you.
