I know this is not the first case in history, but is certainly a not so common occurrance.... How can the slides deploy with the doors firmly closed and with the speed at that stage of the flight ???

I guess is not the best experience for the average "nervous" passenger    http://avherald.com/h?article=46b1cead&opt=0

That must suck. I heard from a very close friend (whose son is engaged to an OZ flight attendant and who was on OZ 214), that one of the flight attendants was nearly killed because the slide deployed inside the plane after the crash landing, and pressed her into a wall. They had to use a couple axes to deflate the chute, and the FA was half-blue by the time she could be freed.

According to the AvHerald report: "The slide subsequently separated from the aircraft."

I wonder where it came down, and if it can be found?

Right...but how is that relevant here?

The over wing slide comes out of the fuselage towards the aft of the wing. It really has nothing to do with the doors!

The slide is in the wing to body fairing and has from time to time come out on its own without door activation, similarly on the 757. Search for inflight slide deployment and you'll find more than a few reports.

A Boeing 757 on a B-1 flight out of RNT took off with the advisory light for the slide illuminated (shouldn't have) and the slide deployed, hit the horizontal stabilizer and fell into Lake Washington. Rumor has it that airplane (if still in service NWA/DAL) flies crooked to this day.

Odds are this event occurred overwater, and the off-wing ramp slides on the 767 are weighted, so it likely sank.

This plane was taking off and climbing out from Bogota, Colombia. The sea is very far , so the odds are this event ocurred over land.

Yes, very quickly I can say with experience. I have not blown one myself, but I was nearby when someone opened the hatch. The disarm procedure is very long and must be followed or it may blow when the slide door is opened for inspection.

Yes, that's the normal way to get it to deploy--I'm guessing this was an "abnormal" deployment.

It is interesting as these slides are fairly heavy and substantial and while severe damage could potentially occur to the ext airframe, they can in fact kill if deployed in unusual circumstances...I rather liked the added aspect and thread diversion.

I'm somewhat worried here about the possibility of interference with the horizontal stabilizer in inadvertent escape chute deployment which could lead to serious controllability problems. If too many more of these instances occur, sooner or later we could have a less desirable outcome.

Slightly weird occurrence. But I suppose anything is possible. I don't want to imagine the passenger's, who was sitting next to the OW exit, face while the escape chute erected. What a scary sight.

He didn't see anything, it probably didn't inflate, was out of his line of sight, just a "thunk" and gone. They probably did have to replace his seat at the next stop though.

What is the chance a slide could impact the horizontal or vertical stabilizer in flight and cause damage?

Based on the comments from people who were on a 757 once upon a time that deployed a slide inflight, it scared the **** out of them and they weren't sitting anywhere near the wing.

I imaging hearing "a loud bang" right next to you would be unnerving for even the most seasoned flier.



I'm tired of the A vs. B sniping. Neither make planes that shed wings randomly!

I would GUESS small, since the chute deploys downwards and the airflow over the wing at that point is flowing downwards so the chute will most likely be torn off at an angle downwards.

Based on what I've seen in films (I know, but it's my only frame of reference), I'd expect the event of the slide deploying to not be particularly noisy in itself- A "pop" as the cover releases followed immediately by "sssss-whump" as the slide inflates like a life raft. However, I'd imagine the sound of a weighted and inflated slide whacking against the outside of the fuselage in the 400 mph breeze a few good times before it finally tore free might be a bit unnerving for the passengers in the rows just aft of the emergency exit.

Very true. The passengers must have been really scared.

If it was me I would be wondering what else is going to fall off or malfunction.

How does an aircraft handle in such a situation? Does it suddenly veer off course?
