I believe the widely accepted (but not universal) format for acronyms is all caps if each letter pronounced...for example MIT. Only the first letter is capitalized if hte acronym is pronounced as a word...for example Nasa.
Historically, MIT is not an acronym since it’s not pronounced as a word. MIT is just an abbreviation (specifically an initialism), while NASA is an acronym.
I don’t think there’s any rules about capitalization and acronyms, as scuba and laser are acronyms, and not capitalized, but NASA is. I’ve also never seen Nasa, it’s always all capitals NASA.
"Detailed analysis by Boeing shows that even where this crack is present, it does not immediately compromise the safety of the aircraft – as indicated by the time-frame given by regulators to perform the checks."
Part of engineering is to form a reasonable understanding of how quickly cracks grow, and then document that as "check for cracks every x/2 days", where x is the number of days necessary for a crack to grow to a dangerous size and 2 is a number I invented ten seconds ago.
It has been said that Boeing has been a little sloppy about that second bit recently, though, so perhaps Quantas is distrustful and has reason. Here for example: https://www.reddit.com/r/videos/comments/bdfqm4/the_real_rea... and I quote: "James had constantly raised red flags about safety corners Boeing was cutting on the 787 rollout. Things like putting the plane out before there was a good understanding of crack propagation speed, nondestructive testing protocols and repair protocols for all the carbon fiber on the plane. These were extremely serious issues that Boeing swept under the rug to get the 787 out faster. Because he wouldn't toe the line on this, James got exiled to the shitty little backwater …"
