Honestly desertboki you are clutching at straws.
It’s been well know Boeing have issues at the moment. You don’t even have to follow aviation to know this. B787 B737 have supply issues this has been going on for a while.
A little bit more info for you. Many new aircraft are delivered and have teething problems. No aircraft is ever delivered perfect. I forget the exact number but they always have something like 40 odd issues. Some might be minor some major. These don’t always show up until a long delivery flight. That’s why they often send the more experienced pilots to collect them so they can report back fully.
You say you worked for flydubai but you don’t seem to know much about aviation.
