Angle of Incidence

[PA1195]

For once and maybe for all...from my Form ACA 309 6/1941: Incidence 3* 45', Dihedral 1*, MAC 61.9", Datum LE to MAC .22"

Gary,
I am not sure that I recall that form number.

Is that the one that says must be in view of the pilot?

If so I have seen them but never noticed the angles, is that standard?

I recall that they had equipment list stuff.

CAA Form ACA 309 (five pages) was filled out and issued at initial certification by the Gov't Inspector who inspected the plane. It proceeded the Flight Manual of later CAR 3 aircraft. There might be one copy in the CD of the plane's records dating back to origination. Lists aircraft operation record (the source of #16) plus leveling means, operations authorized, various specs and datum info, weight and balance, weights and alterations, operation limitations, and equipment list.

The ACA 309 Operation Limitations form or equivalent has to be onboard. A-696 Rev. 25 planes need a W&B to be available. A-696 Rev. 14, A-699 Rev. 6, and A-700 Rev. 5 planes need it onboard.

I found it for my Aeronca on the CD. I had seen them before got confused by the mention of incidence angle. I have never seen the incidence angle or dihedral listed on one.

Interesting that your's has that info.

It has been many years since I have seen one of the original Taylorcraft "Aircraft Specifications" sheets as opposed to the later TCDS.

However I do recall that the Aircraft Specification Sheet said that the production approval was that each plane had to be inspected by the CAA inspector.

So perhaps his inspection included checking those angles?

Yea old stuff for sure. It'll be 79 years next month for N36007 S/N 2972. Lost horizons for many owners and maintainers. Probably easy to verify via FAA CD records if available.

Here's another factoid from 1941...my first Taylorcraft N29694 with Continental A-65 was built 1/1941 under Production Certificate #9. CAA Form 307 and 317 prior to TCDS A-696 being noted were applied. A temporary Certificate was issued and A-696 later appears on paperwork in mid-1942. My current plane N36007 was produced and certified under TCDS A-699 in 6/1941 with a Franklin engine and includes CAA forms ACA-309 mentioned in #18. In 1982 a Continental A-65 replaced the Franklin and the FAA issued a new Airworthiness Certificate calling it a BC12-65. Whatever.

We have 29654, also built January 1941. It is not that the A-696 type certificate wasn't there yet, but rather that the BC12-65 had not been added yet.

Thanks Tom for the information on N29694. It's still a local plane owned by an A&P/IA who's day job keeps him busy. I hear it's being restored. At one time it had an O-290-D2 in the front after I sold it. Lots of mods on that plane when I had it. C-85, Beech-Roby, extended rear baggage beyond SA1-210, Enlarged side glass, Arctic Tern cowling and squared off wing tips and ailerons.
