We also have an AD requiring mandatory overhaul

News to me and I've been following this fairly closely since our prop was
affected by the hub AD issued last year.

Care to provide the AD number or a link to it? I looked on Hartzell's
site and didn't find any such AD.

If you are in the FAA's DB of having a plane in which a Hartzell prop
is applicable you should have gotten this in the mail...
Blades before D47534 are affected. Expect this to grow in the future.

AD 2007-26-09

Unsafe Condition
(e) This AD results from operators
requesting clarification of certain portions of
AD 2002-09-08. We are issuing this AD to
prevent failure of the propeller blade from
fatigue cracks in the aluminum blade shank
radius, which can result in damage to the
airplane and loss of airplane control.
