The International Cessna^® 170 Association

I’m sure this is listed somewhere in the forum, but when I search I cannot get the search narrowed enough. I hope my description is clear enough for you guys to know what I am talking about.

I am looking for the little air scoops that are riveted in the baffling at the front of the cowling. The air is for the cabin heat on one side and the carb heat on the other. I see they are on the expanded view in the Cessna 170A parts catalog. It appears they are part of the front baffling, not a separate part that can be ordered. Does anyone know where and if they can be purchased.

Doubt you can purchase them but you could make them. may not as nice but just as functional. Of course there is always the junk yards.

BTW I don't think they where standard on early A models. I've seen several with out them

Talk to Levi, these guys make and sell any part of the 170A or B baffles, air box or pressure cowl, although some of the parts are different in looks but not function.

Go to the "Baffles" thread in "The Hangar", and look at the picture on page 2 to see an example of the front scoop which is slightly larger than the original.

Howdy Bruce,

My 49 170A has the "air scoops." serial number 18886.
On one occasion, the "scoops" collected a lot of water in the "scat hoses" during a heavy rain storm in Laporte, Tx. The plane was tied down at the time. I was curious during a pre-flight the next day and found that the "scat hoses" each contained about a quart of rain water

I hope this helps......

I make a small slit with an exacto knife at the lowest point of the scat. Just big enough for the water to drip out if it starts to collect.

Thanks guys for the info and the help. I will contact Airframes, Inc. on Monday. If they cannot help me I will make some. A friend of mine has a metal fabrication shop I’m sure he can make them look real nice. Thanks again for all the help.

I made replacement scoops using PVC pipe elbows. Work great.

I keep forgetting about Airframes making the baffles. Thanks for pointing that out.

BL, so you used PVC pipe. Very innovative.

It's a shame you're not a TIC170A member, or you could buy one of the spares TIC170A has sitting in my hangar.

(We have a complete PN 0550112, Baffle assy, front, left (with scoop and with baffle rub-strip {black P-strip attached to front edge}) from 170A IPC, Fig 38, item 46, in what appears almost NOS condition.)

I have thought about becoming a TIC170A member. George, your little hint made me laugh. You will see my membership within the week. This may be a stupid question but what does becoming a member do for a 170 owner, other than give me the opportunity to buy George’s baffling?

Does me being a member give me the opportunity to argue with George a little more, I kind of enjoy that!!!! I guess it is time to become a member. I have learned so much about the 170 and the O-300 since I bought my 170 last December. I have flown 148 hours in the 170, I really enjoy that plane.

I know this is not about the original subject. This will give George a chance to make a new thread.

I do appreciate all the help and information from the members. I guess it is time to show my support to the association.

Pif_sonic, you might want to check out this thread ,Cabin heat with winterization, that Kyle Wolfe suggested. There are some good pics that show an extension on the cabin heat scoop. I don't think I need the winterization kit but I am going to make one of the extensions to increase the air flow through my cabin heat muff in the winter. I'll make it so it can be removed for warm weather.

Thanks Dave. That thread really helped.

Does the winterization kit need to be TSO’d??? I know a guy that will make them for me if it is ok. It appears the covers for the cowling go next to the prop. Is there a reason for that and is it required to go in that location? I would assume the majority of the heat is created and dissipated at the top of the cylinder; there are larger fins at that end. Is there a place to buy the oil inlet cover?

Last year I flew a lot during December, January and February. There were days the oil temp would not get above 180 degrees. My mechanic told me to use 15-50w oil in the winter. Can I get that oil to 225 degrees and still be safe? I usually run 80W in the summer.

Thanks again for all the help and advice.

Wayne, multi-grade oil is OK to 225 F, but not to the 240 TCM authorized for this engine with straight-wt SAE 50.
The reason the cyl barrels are protected by the winter kit is because it's the cyl heads which primarily dissipate most of the heat. The barrels need the protection from the arctic blast. In the U.S. the owner may produce replacement parts provided they are duplicate/replacements of cert. parts. (I posted an article here about that issue which can be researched.)
