Broken Wings And Falling Engines...

Mon Oct 15, 2001 7:43 pm

Has a wing ever snapped in flight? I noticed that during heavy turbulance, the wing moves a lot, and I know this is tested and designed to flex, but has a wing ever snapped, either in its entirety, or just the end part?

As for engines - has an a/c ever lost an engine in flight because of turbulance?

An El-Al 747 cargo plane lost a engine prior to the Bijmer-crash in Amsterdam (1992 or something). I don't know if it had to do with turbulence, I believe not.

wasn't that due to fatigue/corosion in the engine mounting pins?

Early Lockheed Electra's suffered from wing loss during flight as a result of resonance from the engines etc.

You're right Trident3. I got this from http://www.aviation-safety.net


PROBABLE CAUSE: "The design and certification of the B747 pylon was found to be inadequate to provide the required level of safety. Furthermore the system to ensure structural integrity by inspection failed. This ultimately caused - probably initiated by fatigue in the inboard midspar fuse-pin - the no.3 pylon and engine to separate from the wing in such a way that the no.4 pylon and engine were torn off, part of the leading edge of the wing was damaged and the use of several systems was lost or limited. This subsequently left the flight crew with very limited control of the airplane. Because of the marginal controllability a safe landing became highly improbable, if not virtually impossible."

I used to fly on Delta's DC-8's back in the mid 70's a lot when I was a kid, and I used to love sitting over/behind the wing, because the wings on those planes would really move up and down a lot. The engines roared and made a ton of noise which I liked as well.

I know the 737 1 and 200 series engines are designed to where they will seperate under certain circumstances, but whether they'll come off automatically or intentially I'm not sure.

I once read on the NTSB web site about a JAL 747 that lost an engine in turbulance and had to land in alaska.
