FED-EX Engine damage on landing YSSY

[Tony G]

Your correct Tim. I only noticed my photos when i got back from dinner. This is what caused the go around for the A380 and SIA Cargo. Two shots, one in crop of the engine.

Ouch, this damage occurred when the reverse thrust was applied?

[Tim Bowrey]

The aircraft departed RWY34L tonight to Subic Bay as FX77A. She was towed from the bay after sunset so photos weren't good. I will post one of the engine which wasn't in such bad shape.

[Russell D]

Pardon my ignorance, but is there any particular reason why the little door/hatch thingy is open near the "d" on the fuselage painted "Federal Express"?

Outflow valve?

[Erik H. Bakke]

Dumping the overpressure so the doors can be opened

[AdamC]

maybe an overlap in panels.

Who gets the investigation into this matter?

[Brenden S]

It is the outflow valve which controls the air leaving the aircraft when pressurised.

Isn't it country where the incident occured, country where the aircraft is registered, and country where the aircraft was made?

Thats what I have been lead to believe in the past.

[AdamC]

thanks Nick wasn't sure.

my first thoughts were being an incident in australia i thought the atsb or even casa may get it.

pardon my ignorance. I thought that reverse is purely the air in the engine being pushed forward upon reverse to slow the aircraft down. And to prevent ingestion of FOD. So how could this happen. Could it be an airflow problem.

someone please explain?

Sorry if this sounds a bit over the top.

[NickN]

In order for the reverse thrust to work the engine cover slides backwards to allow the air to be blown forwards, perhaps at this point it caught the panel behind it and forced it off.

For all we know the engine could have hit the tarmac although that seems highly unlikely as the Md-11 has a high angle of attack when touching down compared to other aircraft.

Not sure if it hit the runway or not. I was at the terminal taking photos as it landed and Thai 777 aircrew ( who were on Taxi down to the bay, 34L) alerted the tower to some debris on the runway from the FED-EX aircraft. The tower organised a clean up. During this time QF A380 and SIA 747F conducted Go-Arounds.

Just in my opinion, from the damage it looks like it hit, there is quite a big chunk missing. Can the force of the reverse thruster going back in place cause this damage?:confused:

There were a few people behind the old control tower waiting for the A380 including Tim who added his pfoto of the engine on Jetphotos. They might know what happened.

[NickN]

They would have had to drop her on the deck real hard to have an engine strike the runway, the MD-11 touches down with a high nose up pitch.

[Nigel C]

You obviously haven't seen lots of MD-11 landings....;)

[NickN]

Nige, when the MD-11 was in service as a passenger aircraft I was probably just a baby, seen plenty of FedEx and UPS touchdown but nothing that ever caused any sort of alarm. Are there any good clips on YouTube of bad MD-11 landings? If someone knows of any links would be appreciated.

This one is pretty bad:

[NickN]

Holy crap Batman, that was a seriously bad landing AJ. Although, being in a typhoon and all probably didn't make it easy.

[Gareth Forwood]

... and after 10 hours of watching YouTube links, I'm back...

[Blake Riley]

mate of mine is a pilot for fedex told him about what happened to the MD.
He told me that it had a thrust reverser jackscrew break. trying to stow it on rollout dorked it all up

[NickN]

Blake thanks for the confirmation mate.

I noticed 604 on the General Aviation apron this morning - seemingly fixed?

[Nigel C]

It was, but the tug that towed it to the international this afternoon sprung a coolant leak just as it was crossing Rwy 16R, thus resulting in the runway being closed for a short time for the recovery of the tug and aircraft.:eek:

[Philip Argy]

I suppose the word "jinxed" has no place on a technically precise and objective forum like this ... :)

And surely a coolant leak can be ignored for the amount of time it would have taken to tow the a/c clear of the RWY? So what if the tug overheats for an extra minute?

[Nigel C]

It was the appearance of what they thought was 'smoke' that made them stop, and they didn't want to risk the thing by running it any hotter than it was already getting.

I don't imagine the engines on those tugs would be cheap to repair or replace!

Ah, that would explain the sudden slow down we recieved for RW16L on QFA46 with RW16R closed due disabled aircraft! It wound up being a 330kt descent to RW34R.

So it was all fine when they got clearance to cross 16R, yet between when they started to cross 16R and before they had cleared 16R it became impossible to complete the crossing?

Maybe I'd better resurrect the "jinxed" word!
