Can Anyone Identify These Strips?

[JGug1]

It appears that you are suggesting that they
are to strengthen the wing. Is that the case?
I failed to mention that this 337 has Flint tip tanks, extending the
wing 2"(?) on each side.

I would suggest you check the logbook. I am not familiar with the strips but there better be something in the logs or an STC or something

Please let us know

It looks, from the opinions of two IA's who are friends, that they are, in fact, stall strips. I will be talking to a definitively knowledgeable source tomorrow and will confirm their function. I was with the logs yesterday but do not have access today.
I do appreciate the input. This is such a helpful source.

Those look like external straps (structural, not aerodynamic) on the wing - does not appear normal for a Cessna 337. Now if it was a Lockheed Electra - that would be a different story. To me, it looks like either a repair (337) or some structural improvement. Either way, it is not typical and should be avoided in my opinion.

JAG, I am inclined to agree with you. At the very least, they look horrible. Yes, painting them would cover much of that but there is no way they don't interfere with normal air flow over the wing and they HAVE to cost knots. I don't like them one little bit. I am seeking an explanation from the person who has the airplane.
Thank you.

You could also do a records request on the aircraft (may not be filed yet if work just happened) from the FAA ($10) - this may provide the details of the 337 on those straps. Just an idea.

I think its part of Flint Aero SB FA2
