The Directory in the Members Only area is the latest, but its not a copy of the entire directory (no ads, bylaws, etc).

Delaware (DE) is missing. Which brings up a point about the FAA data base. It only has the address of record. Many people have their aircraft registered to a corporation or LLC which might not be in the state the aircraft resides. Such is the case with Delaware. Because of the laws of Delaware it is very popular to have a company registered there. I wouldn't be surprised to find one aircraft registered in Delaware for every resident living there.

Our association info is that which is given us for association purposes and probably closer represents the state that aircraft resides.

More fun with numbers

I've just downloaded the FAA data on all 170s. There are 2836 170s in the FAA databank. 2819 are registered as being in the USA.

Here is a break down of the numbers by state. The first number is the number the FAA has registered. The second number is the number of TIC170A members in that state and the third is the percentage of 170s in the state owned by TIC170A members.
Since I have the info in a database on my computer it is easy to find other interesting facts according to the FAA data.

According to the data 2635 of the 2819 US registered 170s have a Continental engine. Of those 7 are IO 360s.

Only 88 are registered as having a Lycoming with 22 of those being an 0-340, 7 being an 0-435 and 2 being an 0-320 leaving 57 to be an 0-360. There are probably more 0-360s, the owners just haven't updated the records.

There are 13 Franklin powered 170s, 1 with a Wright J-5 and 1 with a Rotex.

13 aircraft are currently in the experimental category and 10 are in the restricted category.

There are 188 aircraft with their registrations revoked. What ever that means. Better check yours.

Here is a break down of 170s left in the US by mfg. date according to the FAA. the first column is the number registered the second the year of mfg. Did know hey made 170s up to 2001 did you.

Actually the year mfg. is not the year the aircraft was made but when it was first registered.

I'm going to try to find the breakdown of serial numbers and the year they where manufactured and I'll post the breakdown by that when I have it.

Thats fascinating stuff. Looks like research for a 170 News article to me! I am surprised there are that many O-340s ... I've yet to see one and I think I've seen half of the IO-360's. When I first started looking for a 170 back in 81 I found one with the O-435 which sounded really nifty till I started pricing parts for that engine. Four grand for a crankshaft in 81 Somebody want to tell me what a Wright J-5 is?

Paul I'm way ahead of you on the story idea.

Using info from the Cessna 170 Timeless Classic Book I've just assigned the actual year of manufacturer to each aircraft. I only need to find the breakdown for the 49 and 50 years as the book doesn't have that instead lumping them together.

Guess what my 170A which looks more like a B model is registered as a 1950 but according to the serial number break down in the book was made in '51.

Maybe it was the prototype for the B model. Yep that's my new story.

Oh and I was shocked at the amount of the 0-340s as well. As that was an STC'd engine each one of them must have been updated by the owner to correct for the installation at the time. Doesn't mean they are still installed though.

It sounds like the FAA will believe whatever you tell them on the registration form. Wright J-5 ( http://www.enginehistory.org/Wright/Wright%20J-5.pdf ) with it's 500 lb propellerless weight on a 170? Probably not. Rotax ( http://www.kodiakbs.com/engines/912ULS.htm ) with 100 hp or less? I don't think so.

I think the date is whatever you tell them also. The previous owner of '98C (serial # 26541) swore up and down that it was a '54 because the original weight and balance / equipment list is dated 10/26/54. By serial number and by the features (panel layout, rear window shape, tailwheel steering, etc.) it is a '55 model. When I sent in the registration (wow, was it really almost 25 years ago ), I put 1955 as the year and that is what shows up in the FAA database. As I remember, by serial #, '98C was about the 37th 170B designated as a '55 model.

Miles

Mine is also a '55 model (by serial number and equipment/features) manufactured in '54. The bank paperwork all came back showing it as a '54 model

Miles according to the FAA records and the association serial number info your 170 was the 29th for that year if they built them in serial number order.

BTW both planes with the Wright and Rotex are in the experimental category so it could be so.

Bruce,

Knowing a few differences between the '54 and '55 models, I checked the IPC and discovered a definite difference in parts that occurs from serial number 26504 to 26505. (Check page 45 for the rear window, and 107A for the tailwheel steering.) I ASS-U-ME that this means that 26504 is the last '54 model. My s/n is 26541, or 37 numbers after the last '54. I don't have my 170 Book with me, so I don't know where it says the year model break is.

Miles

You are right Miles. I was looking at the FAA data not the total production run. So there are 29 older '55s than yours still in the register.

After using the info in The Cessna 170 Timeless Classic to date the aircraft in the FAA database I've found the following. First column is the year and the second the amount found in the database. The on listed as a 57 isn't but has a bad serial number. There are no real 1957 170s in the data base yet the books says there where 36 made.

1. Merrill Field, Anchorage, AK
2. Fairbanks International
3. Lake Hood / Anchorage Int'l

Not necessarily in that order.

One afternoon, I counted well over 20 at Merrill Field alone.

I just checked the FAA database for Nome as I have heard there are a few up there. There are 9 listed in the Nome Region. 8 are in Nome and one in Golovin. We have two in Galena and a Federal employee is getting one in April. Beautiful planes. I hope to polish mine this summer. The only paint on it is small N numbers on the tail.

On another note the Irondog Race passed through yesterday. A past sudent of mine is in the top 8 Tyler Huntington. He races the Yukon 800 boat race(Fairbanks to Galena and back) and they do that with 50 HP motors with a 3 man crew in around 12 hours. I would rather put my body in a 170 instead of beating it to death on the river or trail.[/img]

OK, so Alaska has 100 more FAA registered 170's than CA, big deal -there's another 100, not registered, anyway. I remember years ago a member flew into Palmer, AK from Louisana. Palmer was the first place, of population, he landed. He was so excited at seeing a dozen 170's tied down. He just kept asking me about them and did I know of any Club Members. What club are you talking about sir? There's a club for 170's? One 170 owner - I've heard of that club, there's an old 170 club sticker on my plane. That Cajun kept telling us we should join - Okey Dokie - have a good flight!
