There are many reasons they might not deploy even if armed. Looking at the main gear touchdowns (multiple) and possible power settings they might not have meet deployment criteria. It’s also worth noting that for at least the first 15 years of 767 flying it was not required to even arm them. In fact we never armed them at my airline unless the runway was shorter than 8000 feet as they would ruin a great landing. If unarmed they will deploy on reverse thrust selection. We manually deployed them by easing them out. Made for really great landings. The 767 is an absolute sweetheart to land. You really have to work at it to screw it up this bad.
I’d hate to have been in that cockpit. The go-around was executed waaaay later than it should have. As soon as that PIO started the PF should have gone around and the PM should have called it if not. That was seriously sloppy. The pax had to love it.
It appeared the “pogoing” had resolved. Realize they shouldn’t have been in a PIO situation in the first place, but after bounce settled, did they even need to go around?
