How do US aircraft registrations work?
Air crash on takeoff at Birmingham UK (BHX) today, a Challenger, tail no N90AG, 5 dead. Twelve years ago (4 Jan 2002), another air crash, also at Birmingham, also a Challenger, also tail no N90AG, also 5 dead.
But when I look at the FAA Registry, N90AG is a Maule. How can there be multiple aircraft with the same tail no at the same time?
And why aren't tail nos also unique over time? Surely you don't re-issue the tail no of an aircraft that was in a fatal accident?
Update: My bad. Sorry everybody for wasting your time. There was no crash at BHX on that date. Somehow (I think, listening to the radio), I got the wrong of the stick, and when I checked online, the Daily Mail report page DOES NOT HAVE THE DATE OF THE CRASH IN IT. It only has today's date. So I fell for my own false belief.
I would like to give Best Answer to several of you - but I can't. So I'll give it to the one that answered the headline question.

When a registration ceases to be used on deregistration in the US it becomes available for reissue. That registration has been issued to three aircraft so far. First to a Fairchild which was deregistered in 1991 on export to Italy, next to a Challenger which was destroyed at Birmingham in January 2002 and deregistered in April 2002 and now to a Maule. It has not been involved in any accident since 2002.
Your source of information appears confused.

I think something is wrong with the reporting. Two identical US arircraft with the same tail number at a UK airport with the same number of dead? Hmm.... all I see are reports for the original in 2002. I expect tail numbers are reissued when an aircraft is damaged beyond repair since the original is no longer using it.

Definitely something wrong here. N90AG was a Bombardier which crashed at Birmingham in Jan 2002.
While I might accept that the number could be re-issued, I would not accept that two identical aircraft, with the same registration, crashed from the same runway, at the same airport, in identical circumstances with an identical casualty list.
I am reinforced in that opinion by the fact that there is no report on today's Daily Mail website, nor on the Birmingham Airport website
Someone is kidding someone here!

Only 1 aircraft can be registered under a particular number at a time. However, registration numbers can be cancelled and transferred to other aircraft. And yes, it can be the number from an aircraft that was in a fatal accident. There is no restriction on that.
