Tez Jet Avro RJ85 suffers uncontained engine failure

Another uncontained engine failure, this time on an Avro RJ85. Luckily, engine parts did not penetrate the cabin.

Tez Jet Avro RJ85 powered by Lycoming / Honeywell ALF 502R-5 engines suffered uncontained engine failure and made an emergency landing at Manas airport in Kyrgyzstan.

The four engine airplane with 96 passenger heading from Bishkek to Batken sustained no 1 engine failure shortly after takeoff from Manas airport.

The crew requested for an emergency landing and the plane landed safely after 13 minutes into flight on 1 March 2018.

Ouch! :crazy:

At least it wasn't fatal, but the damage to that engine looks severe.

Must be hard to get a new engine for a Jumbolino these days, so I wonder how they'll manage to get one.

I was on this jet a few days before the incident happened. I think they have another RJ, or they could bring the 146s back :P

See this is why you need 4 engines 4 short haul. ;)

With the Avro's being phased out by most major airlines, ALF507 (the original article is wrong with 502) engines and I imagine spares are easy to come by.

Less than 400 BAE146/ARJ were built.

Of those many have been scrapped or are engineless.

This could be tricky.

Really? Before the RJ craze in the 90s, the Avro was the first RJ really in the US. Remember them in the 80s with Air Wisconsin in United colors at ORD.

Is it true the Avro engines is a short of GTF? Or geared down.

It is a GTF. But obviously, the engine is quite small and so the gearbox involves much lower power than the PW1000 family.

Has there ever been another uncontained failure for an engine of this type? I haven't heard of one.

That engine is also used on corporate jets. so they still make parts.

An interesting fact is that the nacelle is very intact despite what happened.

Interesting. This almost 36-year old aircraft started out in California in 1986 with AirCal (which I worked as an agent in SMF), then to AA and even painted in modified AA livery (grey, not silver fuselage). OC configured it as 85Y having learned from rival PSA's mistake of trying 6-breast 100Y. AA actually reconfigured it as (IIRC) 8F 63Y. Silly. With their frequent engine start failures, we were glad they went away. From AA it went to Malmo Aviation, as did most of the 6 OC/AA 146's. Looking at the serial number history just now, it went on to WDL who apparently farmed it out to most of Europe's airlines at some point. And now Kirghistan. And if there were 96 pax on this flight with the engine failure, clearly they crammed in the 100 seats that never should have been there. BAe actually advertised it as a 106 seater before actually going into service.

(Edit: corrected Malmo Aviation)

It looks like it blew way back in the tail end of the engine; a lot of the other incidents we've seen recently (yes, on much larger machines obviously) have been more towards the middle/middle rear of the powerplant.

This one just a few months ago:

The way the engine is designed the flow wraps back toward the middle before the turbine. The ALF502/507 is a geared fan, axial-centrifugal flow high pressure compressor, reverse flow combustor, two-stage high pressure turbine, two-stage low pressure turbine

I was on a South African Airline Avro about 2 years ago from TNR to JNB and the number 2 would randomly act like it stalled and a puff of black smoke would exit the engine. It almost acted like a compressor stall without the fire normally associated with a compressor stall. I was sitting on that side of the plane and watched it do that numerous times. Each time this occurred, there was a small pop sound from the engine as well.

Why did not sell better? It was the only RJ at the time it was introduced.

Off the top of the head:
low range, bad economics at 5 abreast, bad pax reviews at 6 abreast, 4 engines, repeatedly talks about oil fumes in the cabin, oil crisis in the 70ies.
The 146 was developed for breaking even at 250 pieces, so I imagine it returned a decent profit...

Well, BAe means "Bring Another Engine", so it's living up to its name?

Interesting insight, when you say "engine start failures," the engines won't even start at all?

You have the wrong aircraft. The one in question was built in 1997 (EX-27005).
