If you wrote your N-number/serial number on the correct year Owner's Manual for your plane, is there ANY information in the Approved Flight Manual that is NOT in the Owner's Manual?

Not quite certain what your intent is in this question.....(are you jokingly suggesting that after writing the tail no/serial no ...that all info in the AFM is included????
Or are you asking if there's a method with which the AFM can be dispensed?
Or are you genuinely curious if there's info in the AFM that is NOT included in the OM?)

IN any case, .... the AFM does indeed contain some info the OM does not, but it's unimagineable that a pilot would need to know it or need the info "on board". For example: The AFM gives some details about approved propellers that are not offered in the OM. (diameter, mfr/model, rpm lmits, etc.)

But in general, the OM is much more informative than the AFM is, ..... however the CAA (now FAA) did not give official approval of all the info in that OM. And therefore they do/did not require that any revisions to the OM be submitted for future approval.

The AFM, having official approval, .. (and required info which must be available to the pilot) ... is required to have any revisions also approved.

Bottom line: You MUST have on board a copy of the AFM specific to your MODEL aircraft (not serial.) In order to be considered legitimate, It must have the facsimile of the CAA Inspector's signature and the correct date (as req'd in the Type Certificate, per Item 402, para's (a) thru (m).) (The serial-number entry, which may be applied by anyone, does not have to be present but it looks nice.)

The AFM in my 1955 B-model is original. It's a single sheet, printed on both sides. I scanned it: Curious that they didn't revise it when they added the 10-degree notch to the flap quadrant. (See the required flap placard on the back page.)

John and all.

There are about 5 different versions of the AFM that I have collected. I understand there are also Sea Plane versions. Which one applies to your particular model takes some common sense and reading the header of the AFM. This AFM does not apply to any other model other than the B model land plane.

Obviously John's has his N# on it so it applies to his plane but there may actually be a later version that the one he has which may have included the 10 degree flap setting and might also apply.

I'll check my files tonight when I'm at home.

George-
That is exactly what I was asking about. Thanks. I have a pile of AFM Supplements but no AFM. I'm calling Jan right now.

There are 13 different AFMs as indicated by TCDS, Item 402, paragraphs (a) thru (m) ..... (and is likely the reason it's convenient to identify each by serial number.)

Make absolutely CERTAIN you have the CORRECT ONE FOR YOUR AIRCRAFT, in compliance with the TCDS item 402, para's (a) thru (m).

There are only three choices in the club's 337/STC document list, item 072; 170, item 073; 170A, item 074; 170B.

Richard, the standard 170 B model (landplane) needs item 402 (f) which is:
CAA Approved Airplane Flight Manual for Model 170B, dated September 28, 1950. (check your hotmail, Richard)

The various other AFMs are specified by intalled equipment etc., per the TCDS. Read the "required equipment" section of the TCDS of the model aircraft in question.

I pulled out my copy of my AFM tonight, and contrary to what I spewed earlier in this thread, it has my N-number typed on it!

I actually find it nice to have all the peformance data and reference airspeeds on 1 handy sheet.

George- Those prophylactics make great tourniquets in an emergency. And according to MacGyver, chocolate bars can seal leaking cracks in a sulphuric acid tank, so it sounds like you're all set.
