Fuel Capacity on a 51 170A
Here is another silly question, just one of many more that I will be asking as I put more hours on my plane. My placard by the fuel valve says I have 37 gallons capacity 18.5 in each tank. Is my placard wrong? I was under the impression that every 170 after 1949 had 42 gallons capacity. Can someone shed some light on this for me. Also is there a manufacturer that makes an auxillary tank for the 170? I like to stay up a long time before I come down. Thanks.

I've moved this topic from The Hangar to The Pilot Lounge because I felt it was more appropriately a general discussion topic rather than a maintenance topic. (Primarily because it's an "informed pilot" issue.)
If you don't have a copy of the TCDS (Type Certificate Data Sheet) then you should get one. http:www.faa.gov/
The TCDS gives all the important data about your airplane. You should also get 1) The Illustrated Parts Catalog 2) The Cessna 100 Series Service Manual 1962 and Prior 3) The 170A Owner's Manual, all three are available from Aircraft Spruce 877/477-7823.
Without reading all those documents you do not know all you should about your airplane. They will answer virtually every question.
For example, they all tell you that your airplane has 42 gallons of fuel, 37 of which is useable. (And that is why your placards says so.)

Cruising at 7-8,000 ft and 2500rpm properly leaned I can go a four hour leg with a 45 minute reserve. Just how long did you want to stay up?
To answer your question though yes there is an aux fuel tank by Javelin Aircraft that fits on the floor of the baggage compartment. It's 18 gallons and transfers into the right wing tank after you burn that one off. It's actually on the type certificate as a factory option so a log book entry is all that's required. I am installing one now because I'm converting to a Lycoming 180 hp. Gee with the Javelin and a C-145 you could stay up for say 6.5 hrs with 45 minutes reserve!

Dave,
Where did you purchase this tank? How much was it for installation and for the tank itself? I like flying for long periods north of town here and want the extra range for flying into remote strips, camping out for the night and having the extra fuel for local flying around where I am camping. I am also planning on flying over the Nahanni river next summer and because of the remoteness of it I can't just land and buy fuel in the middle of nowhere and if I want to go check out something along the route that I see, I want the extra fuel. I don't like having to put jerry cans behind the seat, it makes me nervous for some reason. Thanks for the reply.

Regarding installation of an aux fuel tank needing only a logbook signoff, FAR 43 appendix B paragraph (d) states:
(d) For extended-range fuel tanks installed within the passenger compartment or a baggage compartment, the person who performs the work and the person authorized to approve the work by § 43.7 of this part shall execute an FAA Form 337 in at least triplicate. One (1) copy of the FAA Form 337 shall be placed on board the aircraft as specified in § 91.417 of this chapter. The remaining forms shall be distributed as required by paragraph (a)(2) and (3) or (c)(1) and (2) of this paragraph as appropriate. (Secs. 101, 610, 72 Stat. 737, 780, 49 U.S.C. 1301, 1430)

AIRCRAFT INSPECTION, REPAIR & ALTERATIONS from the U.S. Department of Transportatioon FAA. Was about $19. It is a big book, but some of it is on subjects like wood, fabric, etc.

Aux tank paperwork
I asked my I.A. last year about the 337 requirement for fuel tanks in the passenger compartment, since I too have a Javelin tank behind the back seat to feed my Lycoming. He told me that the 337 requirement refers to "Ferry Tanks", and that my logbook entry for the Javelin installation done in '84 is all that's required. Topic for discussion?

Just because something is listed as approved in the type certificate,doesn't necesarily mean that no 337 is required for installation,just that no STC is required.
For example,the 165 horse Franklin engine is listed as approved on the TC,but if you were to install one in place of your C-145 I think that would be considered a "major repair or alteration" and would require a 337.
Just my opinion.....

The black and white of 43 App. B (d) does not state "ferry" tanks. It specifically states "extended-range fuel tanks." Besides, if it's on the TC, then a PMI shouldn't have any problem with the 337 and just send it on through. Seems like the ultimate decision would be the feds, but I read it as any fuel tank added to a passenger/cargo compartment for any reason.

Should take me all of 15 minutes to do the 337. Thanks for pointing it out. BTW the tank is installed, tested, and works great! It can also be removed easily (15 minutes) if you want the full baggage area. Now let's talk about log entrys, W&B, 337's etc for that! (Kinda like the rear seat) No let's not.
