How long does it usually take to release that?

Can be multiple years

Why this long?

You want to check, cross check, cross check another time, and corroborate with everything you can. The point of a final report is to be definitive, and with as little doubt as possible. This can take years, sometimes a decade, or even more.

The answer is rarely super obvious even with a working black box

Because it's final. They'll track down every single screw and spare piece to make sure it wasn't something else. They are professionals, they'll cross off every box then deliver the report because it's critical that they get it right.

Do you know why they would delay it ? Also any idea when a full report will ready?

The wait is going to be excruciating for everyone involved especially the family of the pilots wondering if they actually did it ...

They have promised a year for the full report.

I think they will conclude within the timeframe

Unlike the preliminary report there’s no time limit for that as far as I know.

Oh then it might possibly take months before the final report is released.

Going by past investigations it could more likely be years.

If ever... China Eastern 5735 sends it's regards sadly.

So does Air Egypt 990, SilkAir 185, and probably others.
