my idea was to take out about 1" of the failed tube and
fishmouth(spelling?) both open ends. Inserted tube (with about twice
wall thickness) is visible and can be welded in. How's about this?



I wouldn't even consider it, snake.

This mount BROKE.

It's either too light, or has a stress riser at the break - or both.
(I'm guessing both from the pic)

Consider yourself lucky (you dodged a big bad bullet) and build it again.

Better this time.

It would be helpful to know if there are any more samples of this
airplane design flying, and in particular, are there any more examples
of this engine mount in existence?
If there ARE, then that would focus the debate onto material defect or
construction defect or test rig defect.
Richard reminds us that you didn't see a permanent distortion of the
mount - which is the desired failure mode (supposing that any failure is
desirable) but a clean break - presumably two clean breaks. That should
not happen, ever on a test.
