You guys are lucky. We get all sorts here but our number one is Sunlight Dishwashing Liquid. In fact I used to work in the Unilever factory that made the stuff. I wouldn't recommend using our Sunlight as it had quite a acidic ph to it and was likely to rust out the surrounding metal. The guys on autobody101 swear by Dawn for washing down panels prior to a wax and grease clean.

Not sure how it is in the civilian aircraft industry but in my career at Lockheed Martin building military
aircraft there are no substitutions allowed during assembly . Every technician/mechanic has a set of work instructions for the task they are performing . Those work instructions include every tool and chemical needed to perform the build . ZERO tolerance for deviation unless engineering signs off AND all work planning are updated . Strict adherence " should " mean the end product does what it was designed to do . And that the process is repeatable regardless of the individual performing the task .

Written or electronic work instructions are there for a reason . Many hours are spent mistake proofing and making sure that any mechanic or technician can rotate into a position and perform the task/s as intended . When the individual decides he or she knows better and deviates from the planning that's when bad things can happen . And those bad things may happen years down the road and at Mach3 + speeds !

I can't believe they don't have a procedure. McDonalds figured this out years ago. They could have copied them.

A friend was a highly qualified helicopter mechanic and there were written procedures for everything. And he had another qualified mechanic next to him that checked every nut and bolt he touched.

I guess that's why Boeing is hiding the supervisor or foreman mentioned above.
Edit: Sprint is hiding the employee.

Surprise! PLANE LOSES PANEL MID-FLIGHT

It sure seems like United is having a lot of problems lately? Or does it always happens to every airline, it just wasn’t reported?

Don't believe that for a moment. Very troubled guy who might well have killed himself over the angst and figured it would help his cause.
Not that I doubt that he had valuable things to share, I just wouldn't assume Boeingcide.

Is that the same guy that they said was on 'medical' leave? (Post #196.)

Looks like the cause of the Dreamliner plunge was a loose seat switch-F/A inadvertently moved pilot forward into controls, causing the dive. https://www.youtube.com/watch?v=cRF1YTVJ1Q4

Holy crap. So..... nothing to do with a power loss after all. I've been reading about airliner power systems but not specific models of Boeing 700 series. Seems like there are 2 hydraulic systems and a tail mount auxiliary power module.

I think my questions about 'default' settings under a failure were germane.

another day, another part falling of a boeing.. older 737 Max this time... underside fuselage panel...

Seriously... When reservation sites allow to "deselect" certain airplanes you know it's not going well.

Boeing: we can land with 95% of our panels

Boeing CEO being questioned.

For years, one of my interview questions has been, “if you’ve been instructed to do a job a certain way, and you figure out a better way to do the job, what do you do?”

It’s amazing how many otherwise good candidates are weeded out with this simple question.

In the oil patch, it isn’t always life and death but a cheap mistake only costs $100,000. Countless times, I’ve arrived on location in a black hard hat with no name on my coveralls to ‘help’ (read observe what is actually happening). Numerous times, I’ve had to intervene, cut through the bull5hit and do things correctly. It’s bruised a few egos.

Looks like Boeing cut a deal

We absolutely want to encourage folks to "find a better way", but there are ways of going about vetting their "better way". It usually isn't, but sometimes it really is.

My worst example was a job in Mumbai. A mechanic working on a structural repair in the nose landing gear well was installing a new part that had to be drilled on installation to the surrounding structure. I had provided a drill jig that mounted to established locations in the surrounding structure. It took a bit of time to install, but it would precisely locate the new holes.

"Meh, who needs that? Takes too much time. Damn tool engineers... I'll just drill them by hand." I'm sure you can guess what happened. He screwed up not only the new part, but the surrounding structure as well with his miss located holes, all of which had short edge margins into radii in existing structure, on the new part, and so forth. Now we needed to tear out and replace the existing structure he had damaged (which was out of production at that point, necessitating special order of those parts), in addition to having another example of the new part made back home.

Lead time on all of that was going to be several weeks. The sequence of work would not allow us to "do other things" while waiting. We all got sent home, something like 40 of us. Then sent back a month later when the new parts were available. Business class for all international flights for all of us. Plus, additional downtime on a pretty expensive piece of revenue generating equipment. Gotta wonder what that cost...

And they didn't fire the guy.
