Paperwork--AFM requiremants

[Avee8or]

I am now the proud owner of a 53 170B. In reviewing the papers that came with the aircraft, and the information on the TIC170A website, I note the TC requires an AFM, and that there is a blank landplane AFM for the B on the website. Is it legal for me to insert my N number in the web site AFM and use that? It seems reasonable, given that the AFM does not include information that might vary between landplane 170B's (such as optional equipment). My airplane does not have aftermarket mods, such as vortex generators, that might require an AFM supplement. If this is not the correct path to compliance, what is?

[Bruce Fenstermacher]

You are on the correct path. Print the AFM. Put your registration number on it if you wish, it is not required.

Do you plan on using a winterization kit? There is a required AFM supplement for that.
Does your aircraft happen to have an auto fuel STC (and doesn't matter if you ever use auto fuel), you need the AFM supplement for that.

There are others but these two are common and might apply to you and your aircraft operation.

Do we have a copy of the winterization kit AFM anywhere?
I didn't know this was needed.

[Avee8or]

Bruce, thanks. Yes in both cases, although i will not burn auto fuel. Here in NH, i suspect the winterization kit to be sorely needed! I have not gone through all of the STC paperwork yet, so will see what else lurks there. The 170 is no different...it flies on paper ( only some of which is green).

AFM supplements we've collected including the winterization kit are found here. http://www.cessna170.org/forums/viewtop ... =31&t=9024

Congratulations Avee8or!

When you make it down to central MA, stop in Sterling (3B3) and say hello. I'm the only 170 on the field. Although it's not readily apparent, we have a grass runway parallel to the main runway (left of 34, right of 16). Just say 34 or 16 "on the grass" and you'll be all set if you decide to use the turf.

Is that grass runway marked and registered? I know N38 Wellsboro, PA got theirs marked and registered for liability sake. Reigle 58N at Palmyra PA also has a grass strip to the south and not marked and registered.

It does not appear in the airport directory, so I suspect it's not registered. But you can see that the thresholds are marked in the corners if you look carefully. The local glider club uses it extensively. I've never seen any of their tow planes use anything other than the grass even when not towing. The local instructors use it for tailwheel training and soft field takeoff training for trikes.

That grass runway has been in use for at least fifty years.
One of the smoothest in the local area and reasonably wide.
Smooth even where it crosses the hot top runway exit taxiway.
Used to be a great restaurant at Sterling but it burned - Green Meadow Lodge.

I... Is it legal for me to insert my N number in the web site AFM and use that? It seems reasonable, given that the AFM does not include information that might vary between landplane 170B's (such as optional equipment).

Actually, it is QUITE PERTINENT that you check your equipment list and determine that the generic AFM actually meets the description of your aircraft configuration.

For example, there are numerous versions of the B-model AFM required to be on board ...DEPENDING ON DATE OF AFM and equipment list. An example might be
Dave Bengston's airplane which has the McCauley controllable prop and his AFM MUST be dated July 5, 1955... whereas most 170 B aircraft must have an AFM dated
Sep 28, 1950.

Oh, Wait!!.... you sometimes operate on skis..?? THEN you must have an AFM dated Oct 29, 1951.

The point is that you must also consult your TYPE CERTIFICATE DESIGN SHEET to determine the AFM your airplane requires. (See the req'd equipment list, items 402)
