Cessna 172 Tailcone Stringer
Cessna 172 Tailcone Stringer
(OP)
I have noticed that Cessna designed the 172 D thru 172 I models without a tailcone stringer. I have found some of the K models without a tailcone stringer also. The stringers are 2 J-section that sits on the bottom / side and an L-Extrusion that is located int he middle. Also I have notice that some of those stringers vary on thickness, some of them are .032 and some of them are .051 thick. I know cessna started to add stringers in the L / M model, with a gross weight increase. I know that the stringers are linked to the gross weight increase in some models.
I am just trying to find the history (soap opera) behind the Cessna 172 stringer engineering in those aircraft. Wich airplanes were equiped with a .032 stringer, and wich were equiped with a .051? Did they have a different GW?
If anyone has knowledge on this matter please let me know your 2 cents?!
Have a great day! :)

RE: Cessna 172 Tailcone Stringer
A 0.032" stringer would likely have a different P/N than an 0.050" stringer. Gross weight increases can be tracked through Type Certificate Data Sheets, available from the FAA website.
I've not dug too deeply into 172 IPC's myself, beyond a job on a wing and another on a door frame, so I can't say how comprehensive the book will be. There is a possibility that finding an older IPC would reveal valuable information on the earlier models (in case newer books don't contain that information any more - but I doubt Cessna would do that).
