**I renamed the thread in hopes it will help others find the info looking to do the same mod**

Hey everyone,

I need to pick the brains of those of you that are 205 (Trent) and 206 gurus. I'm wanting to get a field approval for putting the Selkirk extended baggage kit into my 205. My 205 is a 1963 and when looking at the fuselage schematic in the Illustrated parts catalog for it and the 206, U206, and P206 (Serial # P206-001 and on), they are exactly the same. Same part numbers, same illustration. The Selkirk STC specifies that their kit is for 206s from 1966-1973. Does anyone know if there was a structural change in that area in 1966?? By chance has anyone heard of anyone doing this field approval?

I'm looking for any 337s (for a 205 or a 206 that has been modified) to help my mechanic create the documents for the Feds. He has a good relationship with his guy at the FSDO and thinks this should be doable. Any help would be appreciated. Thanks!

Cory

So I've found out there was a slight change in the flooring. Does anyone have a 1966 206 illustrated parts number that you could get me the fuselage and stations pages?

Hey Corey mine is a 66' P206 . Are you just looking for the pages out of POH that have the loading diagram ect . I'll be at hanger tomorrow and I'll take a picture of those pages and send it to you if that's what your after.....Mike

At one time I saw an ad on Barnstormers for a 205 with a 206 baggage. It had a field approval to change out the baggage shelf for the later model 206 lower step that just covers the cables and pulleys behind the bulkhead. It used parts from a later 206.

I have thought of different scenario's over the years but haven't done anything yet.
My 205 has a stiffener on each side behind the bulkhead cover with 2 nut plates riveted in to take machine screws. I have envisioned building a floor to screw down using the existing screw holes. Something similar to the rear baggage floor on a 185.

Thanks mike and Trent!

Mike, I think I found the pages I needed out of the illustrated parts manual online. Don't go to any trouble, but if you have any pics of the structure aft of your rear bulkhead, that would be helpful. Assuming you don't have the extended baggage in their already. If yours is still stock, does your aft bulkhead stop at 124 or 138? Even a pic with the bulkhead in tact (rear of your baggage area) would be helpful come to think of it.

Thanks for the info Trent. Dave at Selkirk was think something similar I think. He said he didn't see why one couldn't fabricate a piece of sheet metal to run along the bottom of the floor, attached to the bulkhead on the sides, to create a lip for his mod to attach to. We are looking to see if the dementions will work. If so, we will try to apply the paperwork to the FSDO prior to buying the kit. Luckily they are willing to help at Selkirk because they are curious to see if it can be approved.

Can you spell minor alteration

Tim

Corey,

My 205 had an extended baggage, I think I sent you a picture of it awhile ago. I sold it to the guy three hangars down so if you need more info I can contact him. I would have to look at the log books for the approval, just don't remember right now. Let me know if you want me to check it out.

Hey Stan,

Thanks for the offer. If I remember right, yours was the Cessna 206 auxiliary baggage shelf, right? When I started calling around to see if the parts were floating around at all, I was told that they are rare and hard to find. One place told me that it was a "made-to-order-part" from Cessna. With that not sounding promising, I thought I'd look into the Selkirk idea.

Worse case we put the paperwork/proposal together and if the FSDO says no, I won't be out much.

My 205 came with this baggage compartment fabricated in what used to be the aft avionics compartment. Its placarded as limited to 20 pounds. Its big enough for misc spare parts and a little survival kit and spare oil. I've got the paperwork for it somewhere (I think it was done on a 337 as a minor?) if you are interested I can scan in and send over.

Here's pics of it:

Yeah, that would be great! Thanks. Another 205 owner friend is working on another extended baggage 337, but if that doesn't work out maybe this one would.

How far away from Selkirk are you? Maybe you could suggest that Selkirk sell you their extended baggage kit, and use the installation in your airplane to add the 205 to their STC? Might take longer but then it'd be a no-hassle approval.

I spoke at length with them. They were very accommodating and gave me the measurements for their extended baggage so I could make a cardboard mockup of one. It became clear very quickly that theirs won't work. Immediately aft of the rear bulkhead are the pulleys for the elevator and rudder and the associated cables that angle up. Their extended baggage won't clear them without extensive modifications. I was bummed because otherwise it's the same structure. The pulleys on a 206 are just further aft. So, the one that my 205 friend is designing will be raised to go over it for the first section and then angle up for the next section to clear the cables. His FSDO has given the thumbs up to design it and has said that so long as it is removable and doesn't affect the structural integrity of the fuselage, there shouldn't be a problem. We will see!

Better late than never, here is the 337 my baggage locker was installed with:

Thanks 205driver!

There's a STC for increased Gross weight to P-206 that includes the extended baggage compartment of the later model 206's. Think it's from Lane Aviation in Ohio . You could use this as the basis for install on your airplane.It comply with fit form and function > don't know about the gross weight increase. Look at N2132F records (64 206) for copy of one we did years ago.

Great news! Two days ago I received my FAA approval for an extended baggage compartment! It's basically copied right out of a 207 and was approved with the 110# limit the 206 has in the same area. I'll be installing it in two weeks. Standby for updates and pictures! This is just in time for our Alaska trip and I'm really excited!

Cool,

Stop by if you get to Homer on your trip.

I would like to see the extension

Good news!

Will do Trent. Are you still in Utah or have you gone North for the summer?

Yesterday was a big day. I skirted some weather and made my way to western Idaho to at long last install the extended baggage mod into my 205. In all, it took about 6 hours, but that included needing to make the back wall and he also didn't like the shelf he originally built for me so he had made another one and needed to assemble it. With all the templates now made, I imagine the install time, with all the parts made ahead of time, would be in the 3-4 hour range he originally estimated. He copied this shelf right out of a 207, which is also the same as for the 206, with a few tweaks. It was approved for the same 120# load limit that the 206 has in the same area. It is solid and sturdy! It should have no problem handling the whole weight limit if for some reason you needed to put it there. We included 6 tie down rings and the back bulkhead is removable for inspections, as well as the inspection plate over the cable pulleys on the shelf. It's all flush riveted so the shelf is smooth and flat. It pretty much dropped right into position, drilled the holes, and riveted in.

Overall, I'm very pleased with it and am anxious to start playing with how to load the plane to maximize the new space. As far as CG goes, it looks like I could put all 120# on the shelf with my normal load (wife, kids, and gear) and still be in CG. I'm hoping to go load the plane tomorrow and fly it.

Installing the support structure on the bottom of the shelf.


Clecoed in and ready to be riveted.


The finished product.


For any other 205 guys out there, Brian said he'd be happy to help you put this in your plane. His company is Wing and A Prayer located just south of Boise, Idaho. A really nice guy that really knows his stuff!
