An other tailwind "surprise"

I just read “Slippery Surprise” in the latest copy of Flight Safety Foundation’s excellent magazine Aero Safety World, April 2010. (Google: asw apr 10 pdf)

An Airbus 321 left the runway at Sandefjord, Norway March 26,2006. It was tailwind, very slippery runway probably causing no wheel spin up and therefore probably no deployment of spoilers and no function of auto brakes. Maximum manual breaking and even parking brakes gave no effect. Wheels were gliding on top of slush. (No surprise for me)

If it had been possible to extend spoilers manually, the load on wheels had increased giving contact with the runway surface.

So this was a ”design induced accident/incident” in combination with tailwind.

Compare with the Airbus 340 at Toronto August 2,2005. It also had tailwind, no wheel spin up and consequently no deployment of spoilers. (Google: Flight 358)

Airbus is, so far as I know, the only aircraft type where spoilers can´t be extended manually.And that stupid construction causes many accidents and incidents killing people and destroying Airbuses. Good business for Airbus. They can sell more aircraft to replace the crashed ones.

Tailwind again

Hello again from captain tailwind, Sweden.
I just read “Slippery Surprise” in the latest copy of Flight Safety Foundation´s excellent magazine AeroSafey World.
Sandefjord March 26, 2006. Airbus 321.

Good business for Airbus. They can sell more aircraft do replace the crashed ones.
