Evac With Door Problems

Sun May 06, 2001 8:03 am

Recently read someplace that with the 747, evac procedures state that, if a door cannot be opened due to a pressure problem, the F/A must break the window with a fire extinguisher to release pressure on the door seal. is this the case? Also, on the 747 door, center area just above the slide pack, is what looks like a small panel, not that easy to see, but gives access to something-access to what?

The small access panel covers the the slide release mechanism to release the slide from the door for maintenance.

I have had a look at our Emerg Procs manual and can find no reference to breaking windows, not that I think you could anyway.

Break a window? I don't know if that's such a good idea. Do you know what airlines train thier F/A's for this procedure?
If there's enough pressure in the cabin and someone manages to break a window, well lets just say I wouldn't want to be near the window.

I don't know too many people tough enough to break an airliner window. Crack one maybe, but break all the way through?? not possible...

Doors like the 747's and DC-10's have a hydraulic blow out function if the door cannot be opened. It is kind of like the hydraulic blow on a small airplane if the gear cannot be lowered. I have never heard of someone being supposed to break a window in a pressurized airplane.

DC10 & 747 pax doors have to come inwards (against any cabin pressure) before they open upwards or outwards repectively

They are called "Plug type doors" will not open with pressure inside the cabin. Also rather impossible to even break a window with the cockpit crash axe. I have seen firefighters on demo use a axe and it was 4 feet long and it just bounced off..

Im not a real pro in this but how about break the whole door if you have an axe???  Smile

Still I agree with Tprop. I wouldn't like to be near that door at that moment...  Smile
