Not sure that merely landing on a taxiway is cause for license

It was an active taxiway. Had there been an aircraft on that taxiway, it would
have been Tenerife all over again, with hundreds dead. That's excellent cause
for revocation of a license.

BTW, what about landing at the wrong airport? Some airliner did that
many years ago, confusing then-Moffet Naval Airstation in the south Bay
Area for the intended San Jose Municipal (back then it was Muni, not
Intl.) Don't know what happened to them.

I haven't heard of that case, but in a case where Northwest landed in the
wrong country (as I recall), the navigator was fired, and I'm not sure about
the others or about their licenses. Landing at the wrong airport isn't as
dangerous as missing the airport by 150 nm or landing on a taxiway, though.
Still, it's a serious mistake for an airline pilot and could easily justify
certificate action.

I saw a bizjet land at the wrong airport a few years ago. A 3-engined
FalconJet landed at my home airport (KEDU) by mistake instead of its
intended KDWA (No. Calif). Runways: KEDU 3176 x 50 ft; KDWA 6000 x 100
ft. This was mid-morning, full sunshine. It was kinda funny for us on
the ground, we all heard the roar of the approaching jet, couldn't
believe it was going to land, and as soon as the mains touched the PIC
kicked in reverse thrust, full power. Somehow he made the turn onto the
end taxiway and parked, found out he was at the wrong place. Even
stranger to watch him take off, we don't get many jets here . We joked
he wasn't going to log that airport.

Was he IFR or VFR?
