The International Cessna 170 Association

Another issue that came up during annual was the lack of placards on my fuel tanks. Are these required placards? My IA seems to thinks so. I don't have the mo-gas stc. I looked at the type certificate and didn't see them as required. If they are required, what do they need to say? Type and qty?

It's hard to believe that my plane could survive all these years without the fuel tanks placarded. Who knows what could have gone in those tanks.

CAR3/4 and it's replacement FAR 23/25 all require that certificated aircraft have placards describing the contents of any tank. The placard should provide the following information: Type, Quantity, Grade.... For example, FUEL-AVGAS, 21 U.S. Gals, 80 Octane.
The same goes for engine oil, hydraulic reservoirs (none on our aircraft), Oxygen tanks, etc.

Sorry for pulling the trigger on this post too soon.

I should stop second guessing my IA...

No you shouldn't stop guessing your IA. He knows it should have a placard, good for him to point it out. I'd bet a beer he doesn't know what is suppose to be included and how it is to be worded on that placard. (He might have been satisfied with a store bought placard that was not correct is my point.)

bluElder wouldn't like it.... (It doesn't include MOgas and MMO)

Those are spiffy!
Do they still have it on file? I'd like to order two for myself.

Wow, the work you did on your filler necks and tanks looks great. Placards are pretty spiffy too!

I happened to be up on the wing today polishing and discovered the remnants of the original placards by the filler necks. The picture is pretty crappy but you can kind of make out what it says.

80 OCTANE
21.5 GAL CAP

It is in the same type of military block lettering as the N-Number. I took measurements and am planning on making stencils and painting this placard back on as it originally was. I have no clue what the color would have been. I am thinking either black or red. From looking over the post from before I wont have all the requirements but if this is the way the airplane came I am pretty sure I can get away with it.

I have a local guy that might be able to make those for me as well.
The graphic makes it a LOT easier to tell him what I'm talking about tho.

On the placard topic, whats the dimensions of the Operating Limitations placard that's normally on the glove box?

4.1/2 x 1. 6/8

Wouldn't it be nice if someone made an entire sheet of original placards for our planes. All the stuff I have found on line isn't really what I am looking for. If mine turn out ok maybe I will make up some extra sheets. No promises...

I started that project. It is much bigger than you think. First you have to find examples of all the decals that you believe to be 100 percent original. Then taking pictures and duplicating them. This is where I'm at for most of the '52 and prior placards. Now I have to print them all and find the originals again and compare to be sure they are correct and if not make changes. Very very time consuming.

As for your tank placards you can duplicate exactly what you have then ad a supplemental placard to cover what is not.

Making faithful reproductions of the original placards is no easy task and I have a lot of respect for that level of effort.

But, my '52 isn't original enough to warrant such an endeavor. She looks like she's out of the 50's but not original.
A decent set of vinyl transfer placards to be legal but not look cheesy is all I really need.

Even though I no longer use mogas I still have the EAA STC placards for fuel type. For quantity, I used Dymo lables. Yes they look cheesy, but you have to either be fueling or inspecting the airplane to notice them, and they've survived about 25 annual inspections.

Cessna Single Engine Service Bulletin SEB92-27, in addition to vented fuel caps, calls for placard p/n 000001 "Avgas Placard - GAMA (80 100LL 100)". That placard is good for everything from the 140A through some 182's so it probably does not include fuel capacity. The placard costs around $4.00 from Cessna.

You can write the information by the gas filler neck with a Pilot Permanent Marker and it will meet the rule.
"Fuel/Avgas/80/87Min Octane 21 U.S. Gals" (Typical A or B model)

I suggest you PRINT it, as most kids that work the line these days don't know how to read longhand.

George, as you well know I have used and advocated mogas in the super hi tech Coninental C-145/O-300 engine for years. However, I have always maintained that MMO is not my thing and pretty much a waste of money. But even if it doesn't do anything for the engine, it probably wont hurt it if you don't dose it too heavilly.
