So I was out flying a practice approach and as I reached the MAP and poured the coals on I heard a pop and the RPMs redlined. I immediately pulled power and discovered I had zero prop control. As we were on 15 miles from home, and all other engine parameters were green I opted to limp back at 14-15", 2500-2600 rpm which gave about 90 KTS. After getting home safely we pulled the cowl and discovered that piece of the prop gov case, approx 1/16" wide and 1/2 " long had peeled back for some reason (obviously something internal disintegrated) and spewed oil over the bottom cowl.
Anyone ever seen of a failure like this?
Anyone have a recommendation for a replacement prop gov (IO-540): MT vs Hartzell?
