Hi Roger,

It was 10 or more years ago and I hired the repair, although I do recall the plate itself did not fail and pulled clean out.  So it was the fasteners or the bedding for them that failed.

I was beating hard into a heavy chop, winds about 20 kt.  That's a lot of sway and pounding for the IMF mast.  Along with the repair, I added a compression post and had stringers installed under the inner edges of the cockpit benches.

Regards,

Rick Lange
