I've looked at a lot of data and want to research the parts manuals looking for clues as to what serial numbers where actually the break between models and years. Some will be easy others we may never know.

I'll post my findings when I'm through investigating.

Got this from Cessna........

170 1948 18000 --- 18729
170A 1949 18730 --- 19199
170A 1950&51 19200 --- 20266
170B 1952 20267 --- 20999
2500 --- 25372
170B 1953 25373 --- 26038
170B 1954 26039 --- 26504
170B 1955 26505 --- 26995
170B 1956 26996 --- 27169

If I read you numbers write Tim in'52 after 20999 they started at 25000 and went to 25372.

So far my research is pretty close you what you have Tim but here is a question. The A model IPC lists obvious A model parts as being for serial 18279 to xxxxx. You will note your list has 18279 as a '48. 8O
BTW 18279 or 18278 are not in the US or CA database so unless we're lucky we may never know. 18730 is definitely an A model and owned by association member Bruce Kown in Georgia.

The first '52 is serial number 20267 which is licensed as a '51 by the FAA but that could be if it was bought and registered in '51. This particular plane is N1625D owned by a Catherine Dwinnell in Anchorage AK.

How about some of you AK guys keeping your eyes out for N1625D around Anchorage and when you spot it see if it it is fact a '52. Should be able to see the dihedral from a few hundred feet away. I'd sure like to confirm this.

I'll have more later.

Catherine is a FedEx captain who lives in Anchorage, she also instructs occasionally. I had the privilege of meeting her at an aviation event last year. Not sure exactly where the plane is based though.

Unless I made a typo those are Right off a Cessna document I have. They may not match the registration years, as they may be the last of the previous or the first of the next year that is why the parts books go by S/N. Then there is the infamous 57 170! :?

Tim would it be to much trouble to send me a copy of that document so that I can keep it with my notes from my research so far.

If you look in the 170B parts manual you will see that it appears Cessna changed the interior panels every year and the parts are different numbers. So there in effect is a break down of the serial numbers of the B models by year right there.

It is the 48 through 51 that isn't clear but I've got it narrowed down.

Richard if you could keep an eye out for N1625D and report back if it has dihedral and large flaps that would be super. I'm sure it is but you could confirm it. Then tell Catherine she's got the oldest B model.

Boy you've got eagle eyes John. To be honest I rarely look at that page.

I wonder if George knew his user name appeared in slow green as well?

Not true, Bruce! My username never appears green at the bottom of the opening page. 8) If you ever find my username in green at the bottom of that page, then it'll be a long, slow day for sure! :lol:

I doubt that Bruce or George are "turning GREEN", but if either of them are they can expect to go a lot faster :wink: Right Joe :?: If George turned green his 170 would go so fast it would burn off that red paint :P
