A320 Fuel Leak

[Boyington]

In the fuel leak procedure for A320 it is stated that No Reversers should be deployed on landing roll. Can someone please explain the reason for this? Thanks

Don't know the official reason but I would guess that the main issue would be as follows:

1) Fuel leak could be coming from anywhere but wings/engines are prime locations for a leak.

2) In landing run fuel leak will be trailing fuel behind as the plane lands

3) Thrust reversers could/would push fuel (leaked) and air forwards an into the engine intakes. This is likely to cause a flame out of the back and cover the whole airframe in a mixture of fuel and air.

4) Atomised fuel air mixture is explosive/fire risk. In general it's better to leave this behind you than spray it in front of the engines :-)

So all in all probably not a good idea - would guess this applies to all jets with TR and not just the 320.

Just my thoughts - actual reason could be more obscure.

One reason and one reason only.
It's to allow the TRE to catch you out that you didn't finish reading the whole checklist. :E

@ EcamSurprise :ok:

Could they have made that note any smaller?

[vilas]

Yes. The reverse may cause re ingestion of fuel vapour into engine intake. Which is hazardous.

The reverse may cause re ingestion of fuel vapour into engine intake.
It is more likely to prevent fuel being thrown over the fuselage.
