Let's not speculate too much. This is not as simple it appears IMO.

I was on the phone with the FAA Engineer this AM. He has a difficult
problem on his hands, and the MFG is not being helpful. We need to
ping the Mfg via Vitek, and the SSA to get on board with this problem.

Accident aicraft had been overhauled in the past, recent annual, and
only 2318 hrs.

I urge you all to look at the overhaul manual, and understand the
structure and fatigue concerns, there is a lot of info there.
