Tez Jet Avro RJ uncontained engine failure - March 2018
Haven't seen any mention of this yet. Has this happened before on the RJ/146 family?

It made the tabloids a couple of days ago.
Despite being described as an "uncontained failure" on Avherald and elsewhere, it doesn't look as if any parts exited tangentially, which is the accepted definition of one.

Joking aside, bits that are spat out of the rear of an engine aren't considered to be "uncontained". That term is reserved for bits that come out sideways, which have much more potential to ruin your entire day.

The jet pipe for the core of the engine is a lightweight thing, held on by a few toggle latches. Turbine parts have come out of it, looking at it, but it is not an uncontained failure withing the proper engine section itself IMHO.
Certainly looks like an uncontained turbine failure to me - based on the picture I'd say a turbine disc let go.

I agree that it may have just missed the official definition of 'uncontained', but I would argue that there's a bit too much twisted metal at the end of the cold stream duct and around the tailpipe. In my view, something flew out that had at least a tangential component to its path. Anyway, I cannot recall many incidents like this on the 146/RJ fleet, which is why it triggered my interest.
Looks to me like the 4th turbine rotor has departed the engine.....its a part that is replaceable on wing....and not the first time a liberation has happened. I suspect it came out whole rather than in fragments as the damage to the cowlings is so neat.

I did a bit more research and found a few examples of engine problems in this fleet. Somehow I must have missed these during an earlier search. Thanks for the information everyone!

hmmm yes they were a bit famous for spitting pieces, particularly the earlier 502 series engines, BAE stood for "blew another engine"...

I do know of one BAe 146 that flew back to base after heavy maintenance with all four fairings stowed in the cargo bay. No damage apart from red faces.

Over the years there have been examples of this engine spitting parts from all three major stages. Early days were N1 blades (high mass high energy), latterly a spate of N2 shreds, often taking out the adjacent engine.
No doubt AD's were produced to reduce further risk, but this looks like the back end and I have not seen this before on any of the ALF/LF series.
Guess if you abuse something for long enough it will eventually fail.
