SAA A340 technical in NY

Sun Nov 26, 2017 7:57 am

An SAA A340 is stuck in NY with fuel contamination, can anyone there give us an update on the situation?

Has sat there with almost no activity for over a week now at a remote pad between T4 and T5. Most likely will require quadruple engine change as well as other fuel parts and fuel system cleaning. Anyone from virgin Atlantic would have better insight as they provide SAA maintenance at JFK and have had a bread truck sitting by it since it got here.
Nothing better than the sound of a 77W GE90-115B on engine startup.

What's a "bread truck?"

Could SAA sue the fuel provider for this? This could have ended up like Cathay 780 when it returned to Africa.

Additives added to the fuel caused the issue, don’t think it was the fuel provider itself but maintenance who added it. Could also have been a bad batch of additives or too much was added.

Luckily this occurred on the ground and not in flight. I find it strange that it happened there and not back in JNB if it was indeed due to biobor treatment.

A truck that delivers bread. A large aluminum box on wheels. Many mtc providers use trucks that look like delivery vans for mtc support vans. They get called bread trucks.

It was done in JNB, it had engine issues coming into JFK but arrived without incident. On Pushback I believe none of the engines were able to be started.

They were doing engine runups on the closed rwy 22R/4L this morning. It’s parked back at the remote bays opposite T4. Still not going anywhere soon.

Just FYI there were no issues coming into JFK at all. The first sign of anything wrong was when none of the engines would start on pushback 4 hours later.

She was ferried home on Thursday as SA4204. Was back in service today on the JNB-CPT run.

Typically engine fuel filter changes and subsequent runs is all that is required on contamination - once you get them running again.
Have never seen an engine change for fuel contamination.

I can second that.

Drain the fuel tanks
Add some Biobor/equivalent
Refuel
Leave it in for a while
Filter changes/runs

...off we go!

How much "old" fuel in the fuel lines that would be used first?
i.e. how far forward towards the engines is fuel recirculated .. ?

( Friends of mine operated an old steam tug that had been converted to heavy fuel oil firing the boiler.
they lamented that it was a pita to start the boiler from cold ( and with light heating oil )
my advice at the time: switch over to light oil before turning the burner to off.)

Basically the only old fuel would be in the fuel manifold in the wings and down the strut to the fuel control units.
