A330-200 flameout / relight of both engines on approach
 
https://thepointsguy.com/news/a330-s...nes-in-flight/

The A330-200, built in 2000 and flying with the Belgian registration 00-SFU, was bound for Brussels from Kinshasa on December 11 when it experienced a failure of the left Pratt and Whitney PW4000 while cruising at 40,000 ft. The pilots immediately declared an emergency and planned to divert to Djerba, in Tunisia, as a precaution. The pilots, while working the problem, were able to get the left engine to reignite, and chose instead to proceed to Brussels.

The flight proceeded without incident until its approach into Brussels. The Belgian aviation saferty agency BEA is reporting that on approach the right-hand PW4000 failed and reignited multiple times. The pilots landed the plane safely at Brussels and at the time of touchdown both engines were powered.

Though there was no point in the flight in which the plane didn’t have one of its two engines powered, failure of both engines during a single flight is very rare. The 18-year old aircraft is still on the ground in Brussels while the investigation into the incident proceeds.

What could be the common element here? Fuel system?

Could possibly be fuel contamination issue similar to this:

Hopefully they can isolate the cause. Engine problems at throttle back can point to super-absorbent polymer (SAP) contamination. The reduced fuel flow causes the fuel temperature in the HMU to increase, dessicating the globules of SAP creating small spheres in the 10-15 micron range that can jam the main metering valves. That was what happened with CX780. Most fuel hydrant trucks have SAP laden filter monitor elements, so the lesson with CX780 will be repeated until the industry learns.

...that can jam the main metering valves.
all sorts of bad things can happen when this happens including an engine stuck at high power during landing approaches as well as the opposite (stuck at low power).

What should have been the appropriate procedure here? While I know this was not an ETOPS flight, if an engine shuts down during flight -- even if it relights, isn't it appropriate to land at the nearest suitable airport -- especially if the reason for the shutdown is not absolutely known with certainty by the crew. It will be interesting to learn what their thinking was in deciding to continue on to BRU.

As long as they thought about it, I have no complaints

I've never understood the logic of continuing if an engine shuts down and you then manage to restart it. It's not as if they shutdown as a matter of course. Something is wrong, even if you don't know what.

Yes, something wrong, but if you are up in the air, isn't the most conservative action to remain up there? Rather than to try to land overweight. The risk of an engine failure is not something that urgently demands you be on the ground ASAP.

Sailvi767 25th Dec 2018 23:58

The only risk for a overweight landing is blowing fuse plugs. The A330 is designed to land up to max structural Takeoff weight if needed.

No, but as you don't know why the engine failed (and then relit) in the first place, isn't the risk really more like the Cathay double failure case.

krismiler 26th Dec 2018 01:02

Departing from Kinshasa and problems with both engines would put contaminated fuel right at the top of the list. Icing could be a possibility as could any work done on the engines during the transit.

Start with the most likely and work from there.

What on earth posessed them to continue to BRU after the first failure?
That really is not very smart.

Yaw String 27th Dec 2018 13:36

Use exactly this scenario during linetraining..you regain a failed engine,either after volcanic ash encounter,or for any other reason.
What kind of flight profile would you use for the diversion airport approach?...discussion point only.
Having had a birdstrike engine fail after 4 hours,at top of descent when thrust reduced to idle,inducing severe surge,a descent maintaining some degree of thrust may have prevented the surge.
if you really don't know why an engine failed,then fuel contamination is a possibility.....Whatever,..a diversion to overhead a SELECTED airport,then let down,so that in the very worst case,you have a better chance should the unimaginable happen.
All food for thought,is it not..
Safe and happy flying for 2019..

Brussels Airlines A330 - both engines failed
 
https://airwaysmag.com/airlines/brus...ngine-failure/

Would you really continue having relit the failed engine? I know I wouldn’t.

Already covered in this thread:A330-200 flameout / relight of both engines on approach

midnight cruiser 31st Dec 2018 10:17

Nor me.

That's two extreme opposite approaches to dealing with an engine failure in a few weeks - Norwegian engine failure (just low oil pressure wasn't it?) - spiral down to a place you really really don't want to put a an aeroplane, it's passengers and crew, when a descent in a straight line would put you close to a good diversion field (KWI) ...

And continuing to destination in a twin, after an engine failure.

The sensible approach must be somewhere between (albeit closer to the former option imo) ..

Agreed... I came across this flight while looking at recent EIO diversions. Looks like the same flight different date?
Geneva to Brussels (287nm) is a bit further than Shiraz to KWI (243nm) would have been.

Incident: Brussels A332 near Geneva on Nov 5th 2018, engine shut down in flight

A Brussels Airlines Airbus A330-200, registration OO-SFZ performing flight SN-359 (dep Nov 4th) from Kinshasa N'djili (DR Congo) to Brussels (Belgium), was enroute at FL400 about 20nm east of Geneva (Switzerland) within French Airspace when the left hand engine (PW4168) emitted a loud bang, the crew received an "ENG1 STALL" warning. The crew shut the engine down, drifted down to FL280 and continued to Brussels for a safe landing about 55 minutes later.

You can get a A330-200 on the ground in 20 to 25 minutes from cruise. There were numerous airports that were suitable in that time frame. The reality is they flew an extra 30 to 35 minutes. Wise or not we are talking about remaining airborne a lot longer than a few extra minutes.

guess the whole discussion is about nearest "in point of time" or as they used to say anyway....
