The aircraft is actually on par with the 777 in the early days, and ahead of other Boeing aircraft at the same stage in their development. Boeing
apparently got a batch of bad circuit boards, which led to the United and Qatar problems. They found 16 boards from one lot that had at least three
bad ones in the lot.
The JAL fuel leaks were both on the same aircraft. There was a design problem with fuel lines, which would lead to them leaking. This was a known
problem, it just happened to hit the same aircraft twice.
