ImageThe spinner cracks around the leading screws over time the flange starts to elongate and washers won’t help.

Thanks for that photo.

That's an absolutely typical problem but one that can be avoided 99% of the time.

As I believe I explained in another post of mine in the forum about XL-2 props and spinners, elongation and 'grinding out' of the holes like that is almost always caused by one or more of the following -
- No 1 Cause: incorrect washers being used under the spinner screws (such as using a metal washer or hard plastic washer instead of the required red fiber washer)
- No 2 Cause: screws being torqued down too hard, flattening the fiber washer and causing the screw head to start wearing on the spinner. (There's a set max torque limit, look for the big post about this subject in the forum, I think the correct torque number is mentioned there, along with the suggestion for buying a pre-set torque screwdriver)
- No 3 Cause: not replacing the red fiber washers when they're flattened, thin, and due for replacement,
- No 4 Cause: not checking the spinner ON EVERY PREFLIGHT in order to catch any issues early, and stop them when you still can by replacing the washers and / or repairing the screw holes.
- or a combination of the above.

The few spinners I have seen in the past that are as bad as yours, were actually successfully repaired by competent composite shops and for a fraction of the cost of a new spinner. But I guess MT in Deland don't do this (?), I might be wrong, but I'm sure you asked them anyway before ordered your new one.

I would not discard this spinner, I'd see if I could get it repaired at a local aviation composite shop and use it as a backup, or sell it on the forum.

Hope that helps for the future.

How much time does the spinner have on it? Be interesting to know.

Gotcha thanks, well that is quite a few hours, but still, should last way longer than that.
Hope you can get it repaired or sold on the forum.
