I am looking for a Door Removal STC. I have tried contacting the holders of the STC, but no luck. Does anyone know how to get hold of them, or have a copy of the STC that I could use for a field approval.

AC 105-2C allows either, but only one, cabin door to be removed from any of the 108 series. There is an STC to remove both?

Although AC105-2C does address door removal, some FSDO look at this application of this AC only for facilitating parachute jumping, and not for the purpose of aerial photography and survey. I will use this AC as a basis for a field approval for these purposes if I cannot get a copy of the existing STC that address this use for door removal. As far as I know the STC are only for single door removals, but I have not seen the actual STC.

Sorry to hear about your FSDO problem. I appreciate the Wichita FSDO more every time I hear someone have a problem. You've probably already argued this, but there is no difference in taking a door off so someone can jump out or taking it off so someone can stay in. The airplane doesn't know the difference. Any performance characteristics are addressed by the AC. It doesn't say you have to land with at least one less person than you took off with. It doesn't say you can only go to 5000 ft, it doesn't say you can only fly for 10 minutes. It does say you can only take one door off, your choice, for whatever reason.
Remember, if you can find a 337 dated before 56, its approved data acceptable to the administrator.
Good luck!

I ran this issue past my FSDO guy. He even brought it up at their staff meeting to make sure he wasn't missing anything, and no one had any problem with removing a door for whatever reason. He did say that it would still depend on what you were doing with a door off for safety reasons. In other words, if you wanted to take pictures, he wanted a reasonable assurance that you wouldn't fall out. Whether that means a net would depend again on the safety factor. We also discussed the reason for it being in the skydiving AC. Best we could come up with is "where else would you put it?" Thats the most likely reason you'd fly with a door off.
Hope that helps!

Digging up a decade old thread, but why is it not authorized to remove both doors? Seems like the aerodynamics would be uneven with just one door removed.

I have jettison doors on my -3 and Univair has the kits available. Not sure if this helps but I can fly without my doors. BTW the doors come off with one pull and goes back on very easy.

@jodyjones

I have jettison doors in my airplane as well. I consider them essential for egress in a floatplane and always brief my passengers in their use should they find themselves upside down in the water. I also tell them not to touch them in flight EVER!!!

Probably comes in handy for flour bombing contests too. LOL
