We work with lots of folks that just purchased a used aircraft or others that are about to sell their plane. We found this article from AOPA very helpful, it really covered all the bases.
While there is a lot on the list to consider, replacing the flooring in your aircraft before you sell can help you get a better price for your plane. It's like painting the walls in your house before you sell to really give it a clean feel.
And if it wasn't done prior to buying the plane, new carpet or vinyl will make this old bird feel truly new to you and modern (ahem, we've seen plenty of orange shag carpet that does not hide it's era well).
We've got hundreds of patterns of floor kits available on our site or you can call 218-728-1614 or email us for custom quotes or with any questions at info@scs-interiors.com. We're available Monday - Thursday 7:30a-5p and Friday 8a-11:30a CST.
