Does this kind of situation happen, or is this a test situation? Are there mechanisms to prevent inward deployment of emergency slides?

  • $\begingroup$ Isn't that an independent raft inflated inside the cabin by accident? This image is used to illustrate such earlier incident on a DC-8. The story itself is funny (use Google translate, the account is written in quite rude style) $\endgroup$

    $\begingroup$ I know there was a crash once, back in the 70's I believe, where one of the slides inflated inside the plane and pinned a flight attendant until someone was able to cut it and free her. $\endgroup$

Yes, they can inflate into the cabin. The FAA has been criticized for not taking better action regarding this and several other escape issues. Consider what happened on July 6, 2013 when Flight 214 struck the sea wall while landing...

Here is a direct quote:

During the crash two of the inflatable chutes deployed into the cabin. The first chute, which blocked the forward right exit, nearly suffocated a flight attendant and was deflated by a pilot with a fire axe from the cockpit. The second chute expanded toward the center of the aircraft near the fire. It trapped a second flight attendant until a co-pilot deflated it with a dinner knife.

When I worked for Continental Airlines, a slide would deploy unexpectedly either while the aircraft was stationary at the gate or while the attendants were opening the door (no fault of theirs). I have never heard of a slide deploying while in flight.

Escape slides are absolutely valuable means to provide safe egress way to ground in emergency evacuation. But it is absolutely true that escape slide can be inflated inside aircraft, so that means safety device can be fatal obstacle to saving life. There were many cases that the slides were inadvertently inflated in the cabin in case of emergency landing.

I wonder why NTSB is so passive to recommend to modify the technical requirement of this emergency equipment. I strongly believe that it should not be inflated at any time inside the cabin.

    $\begingroup$ Hello JINAir, welcome to SE aviation! This site prefers comments to have some authoritative reference to back up answers. The statement "There were many cases that the slides were inadvertently inflated...", will need a couple references or you will find folks will soon mark your answer negatively. Good Luck!!! $\endgroup$
