You take me for an idiot. What apparently happened (apparently) was that it wasn't that nothing happened when the systems went down. Something changed so much to the point that the plane dove at a greater rate than gravity. IOW, it was aimed down suddenly. In the loader comparison, the bucket would have slammed down faster than the rate of gravity. That doesn't happen. I've been around a lot of backhoes and such. If the motor loses power and the bucket is off the ground, it stays off the ground. Yet the plane apparently decided to go somewhere other than into a glide. You would think that (a glide) would be the default, not to nose dive. If I'm an idiot for thinking that, so be it. Quote:

I'm guessing a sensor (gyro/elevator angle/pitot tube) could have been faulty....leading to auto-pilot thinking that rapid diving was best to stabilize level flight.
It thought it was in severe stall conditions and needed to fix it. |
Maybe I missed something..... Re. the wheel coming off, one report was that the wheel hub failed. The nut holding the wheel on remained in place.

The reporter calls the use of dish soap 'alarming'. I would say the only serious issue is that the procedure is not properly documented, or they made up their own procedure. Concerning, but not alarming. And misplaced 'alarm' by the idiot reporter, who failed to grasp the root cause of the issue. |

Post merger with Douglas the culture of the company moved away from a engineering firm to being driven by financial returns.

Not airplane related but:
At the time I wasn't much of a pump expert (I'm a turbine guy) but I was called out to a plant to look at a pump our shop had repaired maybe 15 years ago. The pump packing flange or gland (the thing that pushes in the packing on the shaft to keep whatever's in the pump from leaking out the shaft had fallen off and hit the moving shaft. Why did the flange fall off? They couldn't get the required water drip through the packing (it must leak a little) so they kept loosening it. Why wouldn't it leak? The mechanic said they put anti-seize all over the packing like they had for 30 years before installing it but this time it didn't work. I'm thinking to myself, I'm not a pump expert but I think anti-seize would keep anything from leaking... at all. I start my pump education by finding out what you're supposed to put on pump packing: packing lubricant or if that's not available... dishwashing soap! So for 30 years or more, our whole field pump department was putting anti-seize on pump packing. In their defense, most modern pump packing looks like anti-seize; it's silvery and slick. To this day, I'm still convincing them not to use anti-seize. I also ask every pump expert I meet if they've heard of such a thing and they usually have one case or two they've seen but they're amazed by the stupidity. Of course the main problem is there's no procedure. Our shop has a procedure for almost everything. Except which way the zipper goes. |

Dawn is a miracle product for pressing bushings. Seem to recall using it when I rebuilt the suspension on my now long gone ‘70. Helps install which saves the bushings from tearing damage.

Dawn is getting too much publicity here. I use Ivory Soap for almost everything but the laundry and the occasional dishwasher use. I use Ivory on nails and screws, I use it machining, I wash my hands with it. I've used it as shampoo. No worse than a lot of pricey stuff.
