Back in 1980 an inflight jump door was installed on my 1955 C-180 by field approval. There is no record in the logbooks that it was ever removed, yet it is no longer installed.

I would kind of like to reinstall it.

The question is can it just be reinstalled, since technically it was never uninstalled? If not, can it be reinstalled using the original 337 as a reference?

Not sure if it is worth the effort, but I'm curious anyway.

Thanks for your input.

Since you already have an approved 337, you can remove and reinstall the door all you want without redoing a 337 every time. But since you don't have the door, you need to make sure the one you use now still conforms to the original 337 as that is what's approved.

Example, bushtires. Say you put 31's on your plane via STC or Field Approval. You can remove them to put smaller original tires on and put the bushtires back on later, doesn't require you to redo all the paperwork since it was already done and approved.

Thanks, that clarifies things a lot. Kind of figured that was the case but couldn't get a solid answer from anyone.
