Trijets have been around for a very long time, and aside from the DC-10's various misfeatures, have been rather reliable, even when the number two engine goes out with or without detonating itself in various ways. Given that this plane will almost certainly be fly by wire, I imagine that it'll be a lot easier to design the hydraulic systems in ways to further avoid certain failure modes that did occur in those planes.
Regarding maintenance, the article discusses how the reverse design gives a benefit of having the parts of the engine most difficult to service in a position to make such service easier, so I imagine maintainability will be /different/ but not necessarily worse.

- frik 12y agoTrijet design will almost always consume more fuel than a comparable twin engine design. This results in higher operating costs and reduced range. Although trijets are more efficient than four-engine aircraft, the difficulty and complexity of mounting the center engine through the tail will somewhat negate this advantage. quote from http://en.wikipedia.org/wiki/Trijet http://en.wikipedia.org/wiki/Trijet
