Jeremy,
Who wants to take it out? Is there likely to be maintenance on TP4? If
it was easy to take out now why don't we do that and place the TP 14s
for something better. The fact is it is very hard to take it out now, is
it not? If you had to then the spot weld could be dismantled.
Food for thought.

Because then, Tim, you'll never remove TP4 for maintenance again... At
least, you won't without the need to replace it in its entirety, with
all the difficulty of re-drilling accurately for the TP6 pip-pin holes.
Kind regards,
Jeremy

Why don't we get a certified welder to weld TP12 to TP04 to avoid any
torsion stress on TP6 sleeve?

Graham and Mike,
I agree. Mod 73 is a very poor fix for a bad design. I like the idea
of he single tube with a flange.
I am also concerned about relying on a single pip pin to secure the
tail plane to the aircraft. As there is no way to visually check that
the pip pin is fully engaged and the balls are protruding below TP6, a
pull test would be highly desirable. A special plier would be needed
for that pull test. Alternatively, a big recess on the underside of the
tail plane would allow an uneasy visual inspection with a flashlight.
The rear wing pip pin can be checked that way. Moreover I like the idea
of a back up tail plane locking device such as the spring loaded lever.

I agree with you. A simple redesign would be to make TP5 and 6 one
single tube, with lightening holes, weld a flange on it that bolts
onto
the inside of the root rib. Relying on a bond between epoxy and
stainless steel is not sensible. imho
I still wish we knew more about what went wrong with G-HOFC though.
