Does civil aerospace not use paint pens to mark torque marks on bolts that have been torqued?
Yes we used to use torque seal when we had torqued and or secondary locked a nut or bolt.

Apart from preventing fretting (rattling around), the door bolts in this instance simply prevent the door moving upwards, as long as they are in place the tightness has no relevance in this case.
Ergo, imo they forgot to refit them and only gravity kept the door in the guides and therefore shut.

Ryanair boss seems to have issues with quality control of the planes he's received as well, and thats a totally different model. Its totally unacceptable that Boeing just seem to wait until the regulator points something out, and then does the bare minimum asked of them to be able to get their planes flying again. They should be falling over themselves to show how their quality control is up to par, and maybe have independent inspections of every single plane to allay any concerns. Using passengers as beta testers for the max is unreasonable.

He has a point.

But also maybe he should look for a correlation...

"... largely due to price comparisons with its rival Airbus, Ryanair had found instances of poor standards in new planes sent from America."

Exactly.

You get what you pay for, and Ryanair, Southwest etc have pushed Boeing down a route to retain the custom, which is leading the manufacturer to cut the quality of the product to meet the price point.........and then the customer complains about the quality.

I’m sure if Boeing were shifting more of these planes then the discounts for big customers like Ryanair and SouthWest would be less. Ryanair don’t seem to be in a hurry to get rid of the Lauda A320s, so O’Leary isn’t as wedded to Boeing as some of the other Max operators are. As much as Airbus seem to have a full order book, it’ll be interesting to see if some of the larger mixed operators, eg American, United, start looking to cancel 737 Max orders, especially if they can get the alternative built in Mobile and claim they’re still buying US built aircraft.

Can you really blame the customer for that? Airbus would have been getting the same kinds of pressure from their customers and they pitched their planes at a price, which hopefully included a reasonable quality control structure. If Boeing want to lowball Airbus then it's their fault if they can't deliver due to quality control issues.

I don't blame the customer, but the customer gets what they pay for.

That said, I think Boeing is rotten, as is their relationship with the FAA. It's a form of state support that the US operates to counter Airbus, who they thought was an unfair market disproportionate against Boeing's right to hold their market position.

The ultimate customers are the people who end up plummeting into a field. Are they to blame for the vehicle they are riding in being not really airworthy?

And that story has a link to another story - weeks before the latest mishap, workers at Spirit (who make the fuselage) lodged a complaint

LeverNews said:
documents were filed in federal court alleging that former employees at the company’s subcontractor repeatedly warned corporate officials about safety problems and were told to falsify records.
...
According to the court documents, the employee told a colleague that “he believed it was just a matter of time until a major defect escaped to a customer.”

Might be brand new, might be 20 years old; perhaps a compressor stall, sounds and can look very exciting but unless there's a major fault is straightforward to stop it.

Presumably not much to do with Boeing either; they don’t make engines do they?

No 747-8s have reached the age of 20 yet.

They'd be General Electric on this aircraft.
