Preflight, your likely going to have to make your own if your not satisfied with what is in the Owners Hand Book Cessna provided. maybe you've never seen this book, Here is a link to the '48 version we have for free download to members.
'48 Owners Hand Book

Perhaps others who have 170s would share any they've made.

This site has a link to a free check list of unknown author which I've also attached to this post. Looks pretty thorough. You might have to tweak it specifically for your '48 as it's document name says it's for a 170B.

Again for the 170B/172, Checkmate has a commercially available list I thought pretty nice and pretty much appropriate for the 170B.

Here's the checklist that I have developed over the past month, based on information I have found in the forums and in the Owner's Manual. Send it to Kinkos, print double-sided on card stock, and have them trim and laminate.

It's a work in progress for me and I'm tweaking every couple of flights. Feel free to modify as it suits you. All the legal disclaimers apply here: I developed it for my personal use only and you are ultimately responsible for content and accuracy.

Hope this gets you in the right direction -

Brian

Sure can but you might have second thoughts about the necessity of having one when you see the price tag of new stall warning switches. See fig. 50 of your IPC.

Two major parts you will need are the wing stall warning switch 0413313-1 and the indicator 0413313-2 (with light 0413313-6). Non of the '48 part numbers in this case are available nor are they superseded in the online data. However, we believe they are the same parts fount on the 170A and the 170B, the later where they are required.

Looking at the 170A or 170B IPC you will find different part numbers, some which have to be typos in the Cessna part # or the Safe Flight part number. But I've boiled it down to this. The indicator is 0511062-2, Safe Flight 1-02-000 and lamp 0511062-3). The indicator is no longer available according to CessnaParts.com.

The wing switch is 0511062-4. This supersedes to S1672-5. S1672-5 is available currently at your price of $5827. That is five thousand, eight hundred, twenty seven, I didn't forget the decimal. Knowing the price of these new, salvage yards aren't likely to let them go cheaply but you could try. Salvage yards also know the warning horns are like hens teeth to find and have a value to those that need them. The good news is that most people have no clue what these parts cost and I've seen the horn for $5. I no doubt will see a wing switch some place with a similar price tag.

Maybe a mod can split this topic off as I think it might have legs. First, I'm wondering whether the 48 wing being fabric and possibly having a different wing L/E profile might pose additional difficulties in the install of the .stall vane ? Could a Bendix King KLR 10 be installed and do the same thing ?

To add on to what Jim is saying I think one would have to contact Cessna Technical Support (316)517-5800 and ask for a copy of the stall warning indicator installation kit (52-3-119) instructions. One needs this to accurately place the stall warning switch/vane.

WHY.....oh, ..WHY... would anyone want a stall detector on a ragwing which has such beautiful and clear warnings that it is about to stall...and why is anyone flying around these days on the edge of one?

The B-model is required to have a stall warning because 1.- it has almost no buffet prior to clean stalls and 2.- full flaps will commonly set up a rapid wings-level descent without an actual break and might pass by without much notice to someone asleep-at-the-wheel. (Certification rules required a clear airframe buffet/warning to occur 3-5 mph prior to a stall or a warning device must be installed. The ragwing is a straight wing planform with perfectly predicable stall onset so it met the rule. So did the A-model. But the B's dihedral and flaps so stabilized the planform the natural airframe buffet is almost absent.)

I wish it were NOT required equipment on my B... I'd sell mine in a heartbeat.

Hey George, I was sitting here wondering what I was missing- I have never had any inclination to want a stall horn on my ragwing, in fact I have always been glad it doesn't! The stall has always given plenty of warning without a blaring horn.

I agree. The test pilots probably felt the same way and came up with the disconnect switch (#8) mounted on the piano keys to shut the annoying buzzer off. That switch - and the wires which would be seen underneath it - seems like a tacky way to ruin what is the classiest thing about the panel. Why didn't they use the spare piano key between the master and the turn and bank switch to mount the stall horn disconnect switch? Why the cover on the right side of the panel? Isn't that where the required fuel pressure gauge should go? Finally, why screw the stall warning horn/light into the instrument panel cover? Shouldn't it be on the panel beneath it with the rest of the instruments? One gets the impression that Cessna didn't put much thought into the optional stall warning installation.

I'm just removing my wings for recovering and my 48 has some sort of after market transducer type stall warning device mounted on the left hand leading edge....very ugly looking. For the record it never worked very good so I disconnected it 17 years ago. Anyway it is not going back on after recovering.

Given the cost of the stall warning system I think I would go with a Angle of Attack indicator instead, plus it's more useful information. $390 to $1600 depending on which model you get.
