The next question would be, where does that maintenance take place? A former coworker's hubby was an aircraft mechanic, and he had strong opinions about the trend of setting up maintenance facilities in second- and third-world countries and having the work done by locals there, instead of in the US. His concerns had to do with the ability of non-English speakers to fully grasp technical documentation written in English, oversight of the work, and a fear that the supply chains were more likely to end up with counterfeit parts, which are not built to spec and are thus more likely to fail.
The counterfeit parts bit resonated with me, because I have a brother whose career involved supplying industry, the military, and nuclear power plants with electrical hardware. He had lots of stories about corrupted supply chains and counterfeit parts. Sometimes the procurement persons for the organizations would bypass their established (and sometimes mandated) supply chains because the temptation to save all that money was just too great - and then learn the hard way why that was such a dangerously bad idea.
His best story that can be shared was about a prison that needed a replacement industrial capacitor (these are bigger than garbage cans) for their power plant. They requested bids and my brother, the official sales rep for the factory that built these, submitted his bid. To his shock and horror, the prison accepted a bid from the little local neighborhood hardware store in the small rural town near the prison. There was no way that business could've procured this part - they weren't authorized sellers and the factory confirmed they hadn't supplied them - but the prison ignored my brother's warning and purchased the suspicious capacitor. The cap soon blew up, damaging the power plant and causing a blackout at the prison. The prison had the chutzpah to submit an official warranty/damages claim for the bad cap through my brother to the ostensible manufacturer, who denied the claim, pointing out they'd already been told the factory hadn't built it.
