AA DFW Ground Ops - oops!
 

AA had an 777 that arrived @ DFW from Brazil...taxi in, jetwalk out, passengers start to de-plane...Plane starts rolling BACKWARDS 200', nripping off the door (depositing it in the jetwalk)...Someone "forgot" to chock the wheels...Ruh-roh Scooby!:eek:

yeah, yeah, I know what you're thinking....That's strange but not as strange as finding the box of human heads (50) on the Southwest 737 in Little Rock.

ouch, that's gonna leave a mark. No parking brake?

Once the engines/ hydraulics are shut down, that renders the "parking brake" rather moot, right? MUST chock.

Or, shoulda left it in gear.

the news "media" was saying that the door "FLEW" off
made it sound like an in-flight incident, just trying to scare the public??

I dunno, I've never driven a 777, and I've got no knowledge of their hydraulic systems.

Cars have parking brakes that work when the engine is off.

They should have fit in a hydraulic emergency brake. When the brakes are applied and the plane stops, the HEB is activated, locking the brakes until released.

Just a thought...

Geez what the hell did the pilot think the "P" was for on the selector.

"P" is for push
or is that just Fords

That is the way it works.

Concerning parking brakes on jets, I've never flown a Transport Category aircraft that doesn't have some sort of hydraulic accumulator that hold pressure in the system for some major period of time (many hours), and which allows a certain number of emergency brake applications before running out of pressure. The jet I currently fly has a emergency/parking brake accumulator that allows up to 24 hours of brake pressure or at least six applications of the parking brake.

I can't directly speak for the 777, but I have a hard time believing it doesn't have a similar system. Why the emergency/parking brake was not applied is beyond me.

We aren't supposed to leave the parking brake set on our aircraft if the brake temp monitoring system indicates they are hot. Of course the Captain is required to verify the chocks are set.

Maybe the AA has something similar for the 777. I've seen the rampers chock only one wheel of a dual nose wheel before, that doesn't work so well, maybe that's what happened.

Previous aircraft\ company:
chocks in = brakes released.

the current aircraft\company has the same policy but its due to a unique feature of the airplane. (IE the center gear "walks" during loading)

Yep, brakes off at the ramp. Standard ops. But chalks should be in prior!
