Can F-15s making 9G turns with payload?

Thinking about bolts shearing I wonder if it could have been like
pylon sway brace bolts that would get worn. No visible damage to the
threads, but when you went to torque them down they wouldn't be tight
against the pod. With a pod because of the length you could shake them
and get a feel for a loose sway brace bolt. Maybe 3 bolts torqued up
tight to the plate and one a hair away from the plate would decrease
the load carrying ability enough to have a pod come off?

That could be something of a factor, but the sway brace bolts were a lot
bigger than the bolts holding the MWA to the airframe, and we were very
careful about getting them tight. Multiple inspections, et cetera.

Wasn't something said about mechanics carrying bolts around?
I remember now we use to carry spare sway brace bolts and nuts in our
truck.

We usually inspected the MWAs off of the plane, and replaced the bolts
back at the shop when necessary. Considering the size and external
placement of the sway braces, it was very easy to do a good visual
inspection before we put the pod on.

I remain unconvinced that the ECM pod ripped off as the result
of over-G's like Chad said because any G force powerful enough
to cause AN hardware to fail catastrophically like that would most
likely result in some of the surrounding airframe structure to fail
along with it. But as the old adage goes, **** happens. Perhaps the
bolts were over-torqued and were stretched beyond limits, elongation
of the plate(s), or WTF?

In addition to a small assortment of tools, I sometimes carry around
a few spare pip pins, tie-down rings, tie-wraps, rubber O-rings, and
of course, bungee cords in my A/C. On the first plane I built, I found
that 032" safety wire comes in handy from time to time not just to
help secure things, but also to unplug the carb main jets in the
field.

Bad assumption, in that you think all airframes are always new, always
perfectly maintained, and perfectly designed.

But as the old adage goes, **** happens. Perhaps the bolts were
over-torqued and were stretched beyond limits, elongation of the

Oh, *now* you start to get it. Took you long enough.

I got it from the beginning. That doesn't mean I bought it then, nor
do I buy it now.

It is problematic that the Marron lune just makes things up.
