I agree with Bob. I believe there is a service bulletin (Not an AD)
to fix this. See the K&L site.


This is a C, the service bulletin is for 1-26 D and E. It concerns the wrong bolt being installed in some ships.

It does state that the expected side-to-side movement is 1/8" not the 1/2" that I observe.

The wierd thing is that the play is only right-left, the elevator control linkage has no play. If the cause is an elongation of a hole, I wonder why the wear is in only one axis.
