How is this possible? Surely the terminal velocity of a free falling item like that won’t be much. 100kt?
Why not put a patch on the inside instead? You would need to put in an insert but it would look much better. Crappy repair IMHO.

If you shoot more or less vertically up – then yes, but most probably some idiot shot with a moderate angle – like 10-20 degrees and the velocity of the bullet is still much much greater when impacting the ground.
A quick google find a lot of data on this – the terminal velocity is 100-200mph depending on details.
It would have been cheaper and better looking to just put in another GPS antenna, connected to nothing!
One A&P described this as a “sh*itty repair” (should be done from inside) and anyway the guy got ripped off paying 6k for it. But a TBM gets a bill for 5 digits every time it sees a shop; the owners are used to it.
An antenna would probably require a doubler (pressurised hull) but there will be approved methods for that, so yes that would also work

You mean a patch and a plug plate? It’s only a bullet hole, way too small to rivet on an additional plug plate.
