This may be a dumb question, but why use materials that can corrode on such an important part? Just use stainless steel (or AL or TI), problem solved?
One of the inspection checklist items: Measure the clearance between the flapper bushings at both locations on each engine bleed air 5th stage check valve. If the clearance between the flapper bushings is a minimum of 0.004 inch (0.102 mm) at both locations, the engine bleed air 5th stage check valve at that location has passed this inspection. I knew that aviation engineering dealt with tight tolerances, but boy, it…
The title here should have "737 NG, Classic" not "737 NG Classic". As in "Boeing 737 NG and Classic aircraft", not "Boeing 737 NG Classic aircraft".

Most english speakers also wouldn't be familiar with the term, but it is called 'Headlinese'. https://en.wikipedia.org/wiki/Headline#Headlinese
And it's dumb. We're not setting hot lead into column inches anymore.

I really struggle to understand how you could have used the term "well-respected" here. It ain't muscle memory, this was done deliberately. Could you explain how you can refer to Boeing being well-respected after the 737 MAX fiasco? Maybe I am missing something. [edit] remove a word
Your post seems to imply that a bad product negates the respect earned by leading an industry, nay, multiple industries, for several decades. Do you really truly think that just because the MAX is a POS, that everything that comes out of Boeing can be evaluated under that same lens? Surely you aren't so blind to the reality that engineers do occasionally produce quality work. To your credit, I wouldn't fly myself or…
No I do not. I still wouldn't ever refer to Boeing as well-respected nowadays. Granted, it may be irrational quirk of mine.
To clarify, do I respect Boeing? Yes. But I would not make a post on the Internet and write out "well-respected". I understand Boeing's cultural shift from being an engineering-first company and its MAX fiasco would not warrant "well-respected" in many people's eyes nowadays.
Was Boeing well-respected in the past? Yes. Is Boeing well-respected nowadays? Yes. But to deliberately write it out to me feels like trolling and stoking fire. You surely must understand that a lot of people lost a bit of respect for Boeing in recent years.

Perhaps an odd question from someone who only just found out that feeler gauges exist - do they periodically calibrate or confirm the measurements of the gauges? If someone is sticking the same gauge into tight spaces all day wouldn't it wear down, even slightly, and alter the reliability of the measurement?
They are typically harden steel, so wear minimally and when you test a gap, you’re not really applying much force. If the feeler gauge doesn’t slip in with minimal force, then that tells you the gaps is smaller than the gauge.
The numbers of sets of comically bent out of shape feeler gauges I've encountered in my life demonstrates that there's a bunch of folks out there who don't understand how they're supposed to be used. As in "maybe if I just push harder this'll fit" :)

They are a respected company with many respected products, despite your personal feelings towards them. They did screw up big time with the 737 MAX, but they still have a huge portfolio of well engineered products and will surely launch more well respected products in the future.
They can regain respect by building new good products. Or by admitting mistakes, surely not by laying blame on the pilots.
I am less forgiving. If you want to forgive them, that's your choice.

You don't scrap a 737 for some worn out parts.
This is why I still own most of the vehicles I've purchased over the last 30 years. It is much cheaper to replace worn parts, ideally before they fail, than it is to replace the entire vehicle. I have the skillsets needed to maintain my own equipment and the tools so I just monitor the operating condition of each and replace or repair things as needed. These planes have regular maintenance checks and diagnostics to h…

4 thou isn't a particularly high degree of precision. For about five bucks you can get feeler gauges more accurate than that, and for about thirty you can get a micrometer that's accurate to 0.0005" over a whole inch. (I checked mine against a set of grade 2 gauge blocks at their calibrated temperature.) Normal CNC machines, not designed for extreme precision but the sort of thing an exceptionally serious hobbyist or…
