I particularly like the part where they had to "manually re-ignite the engines before the aircraft hit the tarmac".

Yes. Me too.

Shades of the early service of the F50 at Ansett. The Mascot Glider Squadron was formed and the squadron motto was No Noise, No Worries.

Sir? I wouldn’t be so sure with that comment.

Well itís making all media outlets this event about time the traveling public are informed of the poor quality of these ATRs. I guess loosing an engine seems more important than almost loosing a tail and flying around for 5 days like FVR did!

And here come the haters who have never operated an ATR in their life....

Did you say the same about the 737 after Lion Air? The A320 after Air Asia.....?

Im guessing the aircraft perhaps shouldnít have been placed in that location due to the extreme precipitation at the time but it looks like the auto-ignition did its job and relit when it was supposed to.....more to come on this though no-doubt

Except the systems worked exactly as they should have and re-lit the fires all by themselves. Last time I checked Pratt & Whitney made the engines, not ATR. Hmmm, I wonder what else P&W 100 series engines are fitted to....

The threadstarter's interpretation of what the ATSB notification actually says is quite inaccurate. It was NOT a double engine rollback, initially the right engine rolled back and was automatically restarted by the auto ignition system. At that point both engines were in operation. Later the left engine rolled back and again the auto ignition system worked as advertised and restarted the left engine. At no time was there a "double engine roll back", there were 2 seperate roll back instances. At least one engine was operating at all times.

Read the ATSB's actual words at https://www.atsb.gov.au/publications/investigation_reports/2018/aair/ao-2018-081/

I think most in here get what the thread starter meant, its not worth getting excited about !
That aside whenever I see or know of heavy rain I am about to enter I push those magic buttons, I think the engineers are wondering why the buttons have such deep finger print marks on them after I fly:-):-)

Sir? I wouldnít be so sure with that comment.

Virgin ATR would surely have the highest % of female pilots of any fleet/company in the country?

Xir would like their engines back on please.

Selection of MAN IGN is only found in the EEC fault checklist and in the following conditions; engine flame out, icing, heavy rain etc. ATR have not to my knowledge required this action as an SOP other than for this particular fault/conditions.
Having said that, certainly no criticism leveled at the crew. It will be interesting to see though, whether selection of MAN IGN had any impact on this successful outcome.

Irrelevant.

VA believe that the gendar of the pilot is extremely important. Itís so important that they base their cadet assessment on it.

Nothing to do with the quality of ATRs; CASA should prohibit the loosing of any aircraft parts in public.

Kudos to the crew. Iím sure your A-holes ate the seatcovers. Donít read all the bull dust here.

Yes, I was amused by that... the media make no effort to get anything right... tarmac is a road material, runway, taxiway or apron are the correct terms. It was also said in TND of the Tiger turnback the other day that the aircraft was ďforcedĒ to turn back... by what??? Strong wind, a large hand??? No, neither, rather the PIC Ďelectedí to return.

Am I the only one who is concerned by the fact the crew put the aircraft into a position where the rain was so heavy it snuffed out the fire?

Nope. Nor am I the only one to be bemused at the semantic discussion on the severity of the ensuing sequential failures. From time to time you hear of events where good flying skills were required to save the day after bad judgment caused a problem. I hope that this isn’t one of those cases.

I wonder because here in PNG there is a company that operates 7 ATR's in far more extreme weather than in Australia..... and there does not appear to be any issues arising, at least nothing heard in crew rooms and clubs and other drinking places...

Might be something with the batch that VARA got? the Hevilift ATR had an uncommanded rollback on just one engine just a few days after, I believe theirs is an ex VARA machine?

What's wrong with them?

Losing / loosing - there's a difference.

Maybe it wasnít rain? Perhaps sudden engine intake icing, followed by the activation of the deice boots lead to ice ingestion. Wouldnít be the first time thatís happened to a turbo prop (didnít it happen at a freight company a couple of years ago, a double flame out at altitude, who also did a good job at keeping it quiet?).

Cadet assessment also irrelevant. Take it elsewhere Flyboy (if you must.)

I've got 4 figures on that piece of garbage, and happily stand with the haters. Rubbish aeroplane.

I only ever flew the 600s and much preferred it over the always AOG Dash.

Could've done with a few more horses per side though. It wasn't a climber in ISA+20.
