My Cub is slated for a C90 and Baumann 1500 upgrade.
Back in the Jan/Feb timeframe, I ordered a 76AK-40-2 from Univair. I wanted mine painted black with white tip stripes, but Univair neither offered the paint option, nor would they order it from Sensenich.
So I contacted Sensenich directly, and asked for the paint option on my Univair order. Denise at Sensenich nicely accomodated me.
In February, she advised me that my prop was in the next batch of four props to be manufactured, and that I’d receive my prop in a few weeks.
Within a day or two of that communication, she regretfully advised that an entire batch of their raw forgings recently had failed conformance inspection, and that new dies would be required to create conforming forgings. Sensenich management immediately chose to discontinue the AK76 (and one other model, the number of which I’ve forgotten) which also had nonconforming raw forgings. The decision was made due to the expense, and long payback of the investment in new dies.
I later managed to source a lightly used 76AK-39-2, which upon receipt, I took up to Aviation BL in Quebec for their “5 year inspection “ which is basically a strip, corrosion removal, dressing, conformance check, and repaint.
I was pretty dismayed at the Sensenich decision, as the 76AK is one of very few props applicable to our planes - particularly on floats.
