John,
Thanks for that, your reply is reassuring, I will just keep the
inspections going.
Cheers,
Bill Hamilton.

My 500B has 18,000 hours on it. My rudder pulley brackets are cracked.
Morris includes an inspection of them on his 100hr. inspection sheet. He
informed me that when they manufactured the brackets, they folded them but
didn't stress relieve the corners. He's seen multitudes of cracked ones, and
he says even the ones that haven't been stop drilled only crack to a certain
point. He says it's a problem he's been aware of only for the last 20 years
or so.
He is of the opinion that they probably cracked about 10 minutes after the
airframe was built (ok, maybe a little longer than that). He's also
mentioned that he's never *ever* seen or heard of one failing.
I guess I'll just continue to keep an eye on my pulleys, and see if anything
changes....
