    Most of who I fly with have a Catto, mine ( J4 ) has a certified prop on it

    So you just run with Outlaws? Actually they are so common that when SJ's MT prop needed to be replaced he called me wanting to put a Catto on his Super Cub. He couldn't believe they weren't certified because he had seen so many of them installed on certified Super Cubs. It has been the source of much banter between he and I ever since.

    It's my understanding a wooden prop (as described in the TSDS) is virtually 100% wood, not wood covered with composite.

    Varnish, shellac, poly, splitting hairs? Is powder coat on a fus the same as zink cromate and paint like it left the factory?

    I love a pot that gets stirred. I suspect the "construction" of the prop is the issue. The protective coating, not that much. Although most of the old wood props I see as decorative wall mountings have what appears as brass leading edges. Are those "wooden" props?

    That's exactly what the local FSDO told me. It's the composite component that's their (engineering's) concern not necessarily the wood core. That's their story and they're apparently sticking to it until someone else relieves them of that unknown.

    Edit: A couple of weeks back that Catto subject came up during a brief ramp visit. I asked and they're aware and looking was the general comment.

    So why not offer a wood prop? Maybe the strength's not there in the current configuration without a composite covering.

    I recall when 8:50x6 tires were a concern until they weren't.

    Glenn wears metal rimed glasses, is his head still wooden?

    Depending where you fly, and how much you interact with the FAA, your mechanic may have his own view, and that view is gospel, as it is his license at stake.

    The "wood" props which I've seen have a fabric (usually was Grade A cotton) attached with an adhesive to the wood to prevent splitting of the wood fibers at the tips. What is to be said about extending this "fabric" over the entire propeller? I do not believe that there is any dimension given anywhere. Is not the "composite" a fabric? Pot stirred.

    Does the part 23 rewrite final ruling mean that Catto's might be allowed on certified planes since they are ASTM certified? Effective August 2017?

    I doubt it. Propeller is going to fall under a major component.

    I am new to props, can someone help me out... I see a lot of comments in regards to the BORER props mainly 82/41-44

    My confusion is in the pitch numbers, if you look at the blade from a flat to feathered perspective with feathered being parallel (ish) to the ground, which pitch number is flatter or more vertical the 44?

    Thanks,

    Mike

    I suspect a Catto prop would return most 180 cubs back to their 150 center of gravity.

    Mike,
    "pitch" (second number) refers to the theoretical distance the propellor blade should travel (forward) with one full rotation

    Inches of advance per rotation, assuming no slippage. Hence, lower number is flatter, i.e. less angle as measured from the plane (geometrical plane, not airplane) perpendicular to the direction of travel. Direction of travel being parallel to crankshaft axis.

    So... An 82/44 would be more of a "cruise" prop compared to an 82/41 which would be more of a climb version. Or the lower the number is somewhat comparable to a lower gear in a car.

    Thanks,

    Mike

    Cubs are Part 3 airplanes. I don't see how a rewrite of Part 23 will be of much help. Prop certification is Part 35.

    From AOPA:
    10. Are the performance-based standards applicable to all aircraft?
    No. The new process of using performance-based standards is limited to new airplanes certified under Part 23, ...

    I suspect these changes will eventually affect the way STCs are proven up, but way in the future.

    I spoke with an FAA engineer today asking about a different but similar issue, he told me that the new changes could take longer than expected to get going. For example; he said the new changes will simply reference previous rules and it will simply be done in the futre by looking back to previous rules, until it gets going. Get ready to be patient, again...

    A guy I know (who will go unnamed) runs a Catto prop on his certificated airplane.
    Trying for a low profile, he put a McCauley decal on it. (He calls it a McCatto)
    It might fool some FAA ramp check guy who doesn't know much,
    but everybody who's into this STOL type stuff sees that & gets a big laugh out of it.

    you need to reference the station that the pitch is measured at, when comparing different manufacturer's props.

    Catto Identification

    Can anyone here post a picture of their Catto identification markings? Data plate? Stamping on the hub? The decal on the blades does not count. I have something up my sleeve and would like to see this information. Thanks.

    Thanks Charlie, That one seems to be special for the Carbon Cub. Any others which are not airplane specific?

    The "Glass/Carbon Composite" does not mention wood core. Aren't the Cattos wood core?

    But isn't the "owner" ultimately responsible for ensuring the airworthiness of the airplane? If you knowingly were to do something that the FAA would view as rendering the aircraft non-airworthy (even if the mechanic signed it off), the FAA could have an issue with both of you. And that "knowingly" part is where the penalties tend to escalate and become more harsh. Ultimately, it's your decision...

    Actually I believe it does not matter who owns it , It is up to the PIC to make sure that aircraft is airworthy.
