yes, I was hoping Andy would let us know the progress.
As I understand it, the AN490HT8P rod end fitting failed due to bending,
probably secondary accident damage, the aircraft had had a couple of accidents.
Andy is working on a mandatory mod which will hopefully be available late
February.
We are advised to carefully check the mass balance arm, particularly the
AN490 fitting used to adjust it.
I suppose this is an example of what can happen when taxi or trailer loads
are applied to components designed for flight. I still think the torque
tube pin wear is caused by taxi loads.
