Yep, Hartzell props, AD 2006-18-15. Requires an initial eddy current
inspection within 50 hours time in service then every 100 hours
thereafter. Cost for the inspection where I'm having it done is $300.
Figure another $100 for fuel and engine time and we're up to $400 every
100 hours. At the rate we fly (approx 300 hrs/yr), a replacement hub
(available at a discount, IIRC, just south of 2 AMUs) is the likely
option for permanent compliance.

Ouch. Well that's Harzell for you.

If you're concerned about it, you need to verify your prop serial number
against the AD. If your hub serial number matches the format of the AD
and is a "non-suffix" hub (as in no -A or -B) at the end of the hub
serial number, guess what, you're affected.


No, doesn't affect me now, I put a 3 blade McCauley on my Comanche.
But used to have a 2 blade Hartzell on it that had a 5year/500 hour
AD. I was just curious about the one on your Arrow, seems like Hartzell
comes up with a new AD once every couple of years.
