cessna drawings

mrpibb · Post by **mrpibb** » Fri Dec 05, 2003 4:20 am

Can anyone tell me where to get cessna drawings, particularly the stall warning and venturi. I see the drawing # on the type cert but where would the actual drawing be. I'm doing the annual and there is paperwork on the installation of the stall warning per cessna drawing, and installation of the second venturi per the drawing. Did cessna offer dual venturi's on the 170 or is it a field mod?
Sorry to bore you folks with this question, it's that this is the first annual that I own this aircraft and my IA wants to do a though job.
Thanks
Vic

Unless someone kept the original drawings used to complete a modification with the aircraft records, or unless another member has a set they're willing to share with you, the only place to obtain them is thru Cessna. I wish you lot's of luck. Cessna no longer is willing to share their blueprints and they are only willing to sell you certain of their drawings.
As Parts and Maintenance Coordinator for TIC170A, I have recently begun to acquire and catalog original Cessna drawings for the 170. (Unfortunatley I don't yet have what you are requesting.)
You can contact Velvet at Headquarters@cessna170.org for a copy of Form 337 for the venturi installation for 170B.
Anyone having original drawings for any modifications on their airplane should contact me via email or PM to determine if the association has a copy of your particular drawing. This will help us keep these birds flying another half-century!

Thank you.

George,
thanks, I kind figured this is going to be a tuffie, I am just fortunate ( unfortunate?) that my friend just got back from his IA meeting, and he says that the FAA is really starting to bust ****'s on non compliance and that anything new or resubmitted will require engineering data or the such. So we are trying to cover our selfs just incase down the road.
Also it was mentioned, that if you have a bird in alaska and you get some field work or mods done you lose your lower 48 airworthiness and that you can't sell the aircraft out of state, if you do the aircraft has to recertificated.
Thanks
Vic

An airworthiness certificate is not issued according to state. It is valid throughout the world. A modification or alteration meeting approval basis in any FAA region is valid in all regions.

Your right George Cessna wants $125 for each drawing, A little to steep for me. I guess flying around in a 55 year old cessna product dosn,t count for anything anymore.

I just read an article here recently also that stated that any field approvals granted in Alaska between 10/1/03 and 5/21/05 will only be good in state. They will now be called Legacy field approvals. After 5/21/05 they will no longer do any field approvals. They are allowing this much time so all of the outlaws up here can try to get legal. I don't know how true this article is but I hope it is wrong. I know even now its like pulling teeth to get a field approval up here. I don't see how they could ever totally do away with field approvals. Think of all of the rag and tube aircraft that would be effectivlly totaled if they needed repairs to the tubing. You think there are a lot of outlaws up here now, wait till then.

Vic: ...if you have a bird in alaska and you get some field work or mods done you lose your lower 48 airworthiness and that you can't sell the aircraft out of state, if you do the aircraft has to recertificated.

George: An airworthiness certificate is not issued according to state. It is valid throughout the world. A modification or alteration meeting approval basis in any FAA region is valid in all regions.

Vic's more correct on this one. As of Oct. 7 (?) Alaska's field approval regs became exactly the same as the lower 48's, like they theoretically always have been. Except <g> for something the FAA's calling a "legacy" approval. This is when you want to get approval for something that's historically been done by field approval but is now clearly defined as something that requires engineeering data or an STC. You bring them a stack of previous 337's and you get approval for the same thing - except that it's only valid in Alaska.

anything approved on this "legacy" basis has to be removed before legal flight out of the state. The legacy process is due to expire in a couple years, it appears to be the final step in weaning us Alaskans from any vestiges of practicality in the FAA. BTW, anything field approved in AK before Oct 7 is legal anywhere.

I can't find this in writing anywhere. Closest I've seen was in a PowerPoint presentation at the Sept. IA seminar in Anch, it wasn't even in the handouts.

No offense,but I can't believe this one. I believe it might be "easier" to get a modification/repair field-approved in some areas (Alaska for example) than others. But I can't believe that that approval would be good only for op's in one state.
Perhaps they're gonna split the Alaska Aviation Administration off from the FAA?................
