Just a bit of info for those of us who are "blessed" with this prop. The Feds have just come out with an A.D. requiring the change to a new diaphragm with a tab noting a batch/lot number. Effective date is Aug 30, 2013. According to the AD, the new one(P/N B-119-2) needs to be installed within 12 months of the effective date of the AD. Cheers. Tom Robinson
