Etihad Plane in Trouble - Melbourne

[Sprucegoose]

Yes, my apologies for trying to have a life outside of AFF.

Apology accepted.

There seems to be an issue with the Etihad flight leaving Melbourne this evening—it's circling over the bay and dumping fuel.

Dammit, I was fooled! I thought this post was about an Etihad fuel dump but instead it was an emergency on board! So much for the days of Canada Dry fuel dumps.

Plane in trouble apparently. Do we have a link that explains the emergency on board?

Given it'd just taken off & I presume it's fuel tanks were pretty close to full (as I assume it was heading to the Middle East which is a decent distance) ... it can't be good having that much avgas dumped? I mean obviously better than a giant full 'plane consumed by a fireball ploughing into a crowded airport terminal, but it still can't be good?

Would the same crew really be allowed to operate MEL-AUH with a duty time 5 hours longer than planned?

Good question, @jb747 might have some intel.

I think it’s unlikely EY would have a set of 787 crew here on standby.

just about every aircraft is designed to land safely fully loaded. I mean if you are dealing with a serious issue, you’re not going to waste an hour dumping fuel (some aircraft’s were lost due to pilots making this error). However, the issue with such arrivals is that you cannot bring them back into service right away, inspections have to be completed to determine whether the heavy landing damages aircraft components like the landing gear.

So I suspect in this case the crew made a calculated decision, the issue wasn’t severe enough for them to require an immediate landing but was serious enough that they couldn’t make it all the way to Abu Dhabi. So in such instances dumping fuel to perform an uneventful landing resulting in the issue being fixed and the bird refuelled in a couple of hours made the most sense.

With respect, there are issues with overweight landings and I would suggest leaving it to the pilots and other appropriate experts to comment on the technical aspects.

To be fair… this isn’t the ‘ask the pilot’ thread!

IIRC in that thread (ask the pilot) it was stated by one of the pilots that planes can land ‘overweight’… but requires inspection etc.

KF88’s proposition makes sense… if the lives of all those on board were in immediate danger, an overweight landing would be better than no landing at all?

Well it ended up departing 2328pm local after an assumed engineering check. Sure will be one heck of a long duty for the crew.

Would the same crew really be allowed to operate MEL-AUH with a duty time 5 hours longer than planned?

The duty period would have been somewhere around 20 hours. The CASA limits were 20 hours, but who knows what (or indeed if) the UAE limits are. I'll see if I can find out.

I am guessing their hours are regulated by their local aviation authority.

Yes, although it's pretty much a department of EK/EY.

Of course they wouldn't. Nobody does.

All aircraft can be landed at their MTOW immediately after takeoff.

Overweight (NOT HEAVY) landings require inspections, depending largely on the assessment of just how smooth the landing was. For that reason, it's generally recommended that they be autolands. An overweight and heavy landing is the worst of both worlds, and wouldn't be back in the air any time soon.

The decision on whether to return immediately or not is up the the Captain. Not all that many things really force an immediate return, and virtually all involve fire of some sort. An engine issue, even including a shutdown, doesn't need to be hurried. I'd know what their issue was, but looking at the approach numbers, it doesn't look like they had a shutdown. Perhaps they just realised it was a 787 and got scared.

Is that a demonstrable Airbus bias I detect?

I would be shocked if any aircraft would be allowed to be manufactured if it could not land at or near the MTOW. Emergency situations on aircraft are rare, but when they occur pilots need to have the ability to make split second decisions safely. That's generally why there is a safety margin built into most aircraft.

The duty period would have been somewhere around 20 hours. The CASA limits were 20 hours, but who knows what (or indeed if) the UAE limits are. I'll see if I can find out.

What rules generally apply for these flights? Would it be CASA since they are departing from an Australian port or would it be the nation of the carrier (i.e. UAE)?

Great to hear confirmation on that.

An overweight and heavy landing is the worst of both worlds, and wouldn't be back in the air any time soon.

I'm guessing that's why generally if the pilots deem it is safe to do so, they'll jettison fuel first then land at a safe weight.

An engine issue, even including a shutdown, doesn't need to be hurried. I'd know what their issue was, but looking at the approach numbers, it doesn't look like they had a shutdown.

I could think of a couple examples where that would be necessary. For instance, dual engine failure (e.g., miracle on the Hudson or Gimli glider). If you're in a situation like that, weight doesn't matter any more, it's all about getting the right glide into the airport.

More like a bias against Boeing.
