Does either option provide any insurance for you?

If you are a part owner in the plane, make sure you are listed as a
'named insured' on the insurance policy (or that the policy includes
a 'no subrogation' clause). This will help prevent the insurance company
from coming after you in the event they pay the club for a claim.

Will you be responsible for any deductibles in either case?

More importantly IMHO
If someone fries the engine tomorrow, are you on the hook for a share to
buy a new one?

What is your share of the deductible if someone writes it off?

Is there an account that saves toward major items like engine rebuild?

Owning part of the plane can be good - because you have an asset that
you can sell - but make sure you understand all of your assumed
liabilities.

I hope that this helps,

Welcome to the world of flight!
