I've received no further news since my last post. I'm assuming that the AMOC has been submitted by now; they expected to submit it very soon after my last post.

I was wondering the same thing. Is the AMOC addressing the issue or the AD or both? Seems to address the AD but after reading those reports I am not sure about addressing the issue ... . Might just be my ignorance... . Let us know if you learn anything off line.

I just checked in with Justin Carter at the FAA - he still hasn't seen a formal request for the 2020-25-12 AD AMOC from SAP.

I called Bill Ross and he stated his boss said the AMOC was a sure thing
Then Bill said to let him know when we would be ready to send the crankshaft
But I stated I wanted in writing that the AMIC has been approved and also a list of items is going to supply so we’re not duplicating them at the engine shop

We hung up and I stated I would contact him on Thursday Last week because I was really getting ready to do this
Called Thursday. No response
Called Friday left message no response
called Monday left message. No response.

I think your right it,the AMOC, has not been submitted yet.

Hoping for the best

I have a slightly different and somewhat more hopeful update.
I sent a short email this morning to Bill Ross and Rhonda at Barrett: "Any further updates? Still hoping to set up a timeline..." Later this afternoon I got a call from Rhonda; she gave me the impression that although the AMOC has not been officially approved by the FAA, it has been submitted by Superior. Bill told her that he was granted permission to begin supplying the replacement parts for the rebuilds in anticipation of the AMOC being approved. I was advised that it may be a good idea to get my engine to Barrett fairly soon so they can prepare for the rebuild. This was motivation enough for me to begin the journey...

... at least out of the shop and to a garage bay to facilitate loading. It will be a few more weeks until I can depart; my wife Amy is recovering from rotator cuff surgery and I shouldn't leave until she's able to drive and load her walker in and out of the car. Rhonda said that one customer that used a replacement crank already has his rebuilt engine back. Don't know all the details yet, but when I know, you'll know.

Over the weekend I opened an XP-360 up for crank swap.

1. Found bearings are not doweled.
2. Thru studs are not doweled.
3. Brand new engine from Superior had ECI rods in it.

Thinking about sending the crank off to have 1&2 addressed.

Superior lists the dowels and appropriate bearings here:

Wondering if anyone else has noticed and done anything about 1&2.

Personally, I'm not taking any steps fwd on this thing until I see something in writing. I have less than 4 hrs of ground operations on a new motor and haven't heard a thing from Superior. Just seems a little insulting to me
danny
with his "ticketed and ready to fly" paperweight.
but I do believe it's probably the most expensive paperweight ever!

Opened my XP 0630 case to replace the crankshaft - I was lucky enough to find one on my field - and found the front main bearing not properly nested. Probably why I had such a devil of a time splitting the case. Also lots of fretting in the saddle under the bearing. My confidence in Superior is seriously waning.

Talked to a knowledgeable crankcase guy and he said the hi-crush bearings used in the XP engines are better than the doweled bearings. So no issue there.
