Looking for a metalized fuselage with a baggage door

I am looking to add a baggage door to my 108-0. The first step is finding the paperwork for a metalized fuselage that has a baggage door. My IA wants this paperwork so we can get a 337. Also, maybe a few picture of the door installed too. I appreciate any help.

My wife informed me she is unable to pack for a weekend trip in a backpack, so it’s come to this.

I checked my database of 337s and I do NOT think I have one of adding a baggage door, especially not on a metalized one. I think Kyle Odam is working on some engineering of adding a baggage door to a 108–1, so maybe contact him for some intel. 

If you find this data, please share back to me so I can add it to our database.

I recently sold my metalized 108-2, Miss Rose. She now lives in Kansas however I hear that the current owner might have her for sale. The N number is 9419K if you want to try getting ahold of him to get some pictures or whatever. Being a 108-2 it had a baggage door from the factory but the Ruleto metalizing kit went onto the fuselage just fine. It all looks like it left the factory that way, a tidy installation.

If memory serves, Univair markets a set of approved documents to install a baggage door and cargo compartment into an earlier airframe. They might even have the parts new but I don't know on that. For sure you could use their approved installation documents and parts from a salvaged later model airframe. Earl Allen should be able to set you up with the parts from his parts birds. With the Univair FAA approved documents your AI should feel content, I should think. The installation of the door/cargo compartment and its structure is all the same for a fabric or a metalized plane, the only difference is the skin is rivited to the door frame rather than glued on fabric. I presume your metalizing job was done with an approved kit rather than a one-off homebuilt arrangement.

Putting the baggage door (and the associatiated cargo compartment inside the fuselage, the door is no good without a place to put the stuff once it's through the door) into an eary fuselage is relatively straigtforward but does require lots of access. It is a big job in terms of the labor involved. If your fuselage is metalized you would most likely want to drill out the rivits in the skin sections in that area (and remove the skins) to open up the work space and then reinstall the skins once the work is complete.

To install the baggage door in accordance with the approved plans you do need to cut out one diagonal fuselage tube and substitute a couple of angled tubes to open up the space the baggage door is in. The installation documents from Univair show how to do it. I remember one person saying they did the Univair baggage door upgrade and just left the diagonal tube cutting across the inside of the door opening. He can only get things into the baggage compartment that fit around the obstructing tube but it saved him some cutting and welding on the fuselage structure. Life is full of choices. Since that method requires deviation from the approved plans it might require a 337 to get the deviation approved, I don't know.

Where in Kansas? I’m in Wichita. 

I called Univair and they do not have an STC or plans for adding the baggage door. However, they would send me the drawings. 

I ended up finding the floor, door and frame, and front wall from someone parting a 108-2 out. I’m going to drive up and get that to start making plans.

@leeacfigmail-com Assuming he still owns the plane he is in Ottowa, KS. I do not feel comfortable giving out his name or contact info without his permission. He bought Miss Rose the metalized 108-2 from me last Thanksgiving. As I said earlier, the N number is 9419K if you want to try and find him and see about getting some pictures.

A couple of years ago I took pictures of Rose's aux fuel tank installation for a guy who wondered how the installation looked. I did get a partial of her baggage door in that batch of pictures and will attach it. You can ignore the aux fuel tank at the cieling of the cargo compartment and look at the part of the picture that shows the skin meeting the door frame. The picture is looking up and aft, so the top of the door is where the aux tank can be seen up at the top, and the vertical part of the door frame is the aft portion. The door frame is mounted in the usual way (per those drawings Univair has) and the metal skin is just rivited onto the outer flange of the door frame where the fabric would be glued on.

With the Univair drawings (approved data from the Type Data Owner) and a bunch of original factory parts from that 108-2, I fail to understand your mechanic's reluctance to do and sign off the installation of the baggage compartment. Good luck.
