I'll raise you with this PDF report on a 737 problem, where for no reason that can be discovered, autothrust just shuts itself off, uncommanded. Oh yeah, and the warning system that tells pilots it's just happened may be inadequate!

But that just goes to show the level of monitoring which goes on worldwide on all aircraft to ensure what are rare events (given the number of hours the type has flown, versus the number of incidents), are fully investigated and corrective re-design put in if required. Because I bet very few of you were even aware of this incident (Small regional airport, charter airline, no casualties, probably didn't even make the press), but it's been the subject of a full investigation by AAIB. And that to me is why no one aircraft type is safer than another - because they are all closely monitored and investigated as soon as a possible problem may be detected.
