767 Escape Slide Inflates Mid-flight

Interesting story here about an Air Zimbabwe flight to Gatwick last summer. When coming into land the pilots noticed the aircraft was reponding strangely, and an after-landing check found that one of the emergency slides had inflated and completely detached from the aircraft.

Now, this raises many questions and about safety; indeed the report states that old parts may have caused this incident. But wouldn't / shouldn't someone have noticed? And had this slide caught on the wing, or been sucked into the engine, couldn't this have been a full-blown mid-air accident?

it sounds to me like it was the overwing exit escape slide. the same thing happened to one of our 767's at usairways while landing in ams a few years back.

good thing it was an over wing slide stored in the wing itself, other wise god knows what kind of injuries if it was a regular exit slide

That would be an interesting situation inside the plane. Talk about your in-flight entertainment! I'd pay $2 to see that!

This does not mean that Air Zimbabwe's Maintainence teams fault that the slide deployed.
There could be a series of events that happened on this flight to cause it to deploy....

Its very bald to go around saying airlines have bad MX....

According to the AAIB report. The plane was on approach to Gatwick. The Slide did not inflate, the door was secure, all that happened, is the panelling came off and the slide compartment fell away. Not quite as drastic as the media puts it.

You'd pay $2 to see people die? Do you realize the force that those slides have will kill instantly if it hits a person while inflating?

How would it do that form inside the aircraft? Guys - the incident described above is only possible with a slide that is stored outside the aircraft, like some over wing slides. All other slides that are inside the door will inflate inside the aircraft unless the door is open for some very odd reason.

Soooo if your flying Ryanair and there's an emergency, and they have to deploy the slides. Do you have to swipe a credit/debit card before you can exit down the slide?

if i rember correctly my TR. 767 has this kind of slide at doors 3LR.

Whilst much is made of the fact that it was an Air Zimbabwe 767, a similar slide deployment occured on either an Air NZ or Qantas 767 when operating through Auckland a few years ago. As already mentioned, these are wing mounted slides. Given the US Air example as well, this shows that what happened to Air Zim is not out of ordinary.

The same Virgin Atlantic 747-200 (ex-QF) had an over-wing slide separate and fall from the aircraft twice during 1996, once after departing LHR and once after departing JFK.

767 overwing slides are stored in a panel in the wing to body fairing not in any door.

They are set up so that if the panel opens it triggers the slide. Its a rigging issue usually.

Its kinda hard to miss if you are a pax in a window seat over the wing and it deploys.

It cant get into the engine because it is behind the leading edge. The airflow over the wing will push it aft.

Since it's above the wing, it would be very hard to get stuck on the wing leading edge or enter the engine...caught on the tail, maybe, but I suspect the aero loads would just tear it off.

Even if it went through the engine, it couldn't take out both engines. Single engine operation isn't a safety hazard.

Everybody keeps talking about the slide getting sucked into an engine. Not the worst-case scenario at all.


What I'd really be afraid of is a large portion of the slide damaging the tail or horizontal stabilizer. A 767 will fly with a failed engine. A smashed-up tail or stabilizer, however, is potentially another story.

Poster Tdscanuck has it totally wrong. He is also off his rocker in writing that, "Single engine operation isn't a safety hazard." My above statement notwithstanding, he is being a little too casual about it. Of course it's a f*%#% safety hazard!


(Meanwhile try to go easy on Air Zim. I know they're a tiny company, but they have a good record. They haven't had a fatal accident since Air Rhodesia days!)

And Air Rhodesia's only fatal accidents were two Vickers Viscounts shot down by SAM missiles in 1978 and 1979.

That must be why all of the OEM's and the regulators catagorize an IFSD as an economic, not a safety, event. Single IFSD's are *far* more common than just reading the press would have you believe. They're not exactly routine, but they are not considered safety events for certification or risk analysis (the do impact ETOPS risk analysis, but that's because of the risk of *dual* engine failure, not single).

There's a reason that all the safety-critical FAR's are met on one engine (for twins).

I understand the technicalities in terms of regs and certification, but as a practical matter, of course it's a safety hazard.

You wrote, and I quote: "Single engine operation isn't a safety hazard."

That's ridiculous. You just lost one of your two engines. It's not a dire emergency, but it's it's serious, especially in an ETOPS/EROPS situation.

Not to sound snippy, but I am relatively conscious of the complications and implications of losing an engine in a 767, since I fly one for a living.
