It does not seem it is Boeing's issue at all.
I believe it was CX.
1. If it is a manufacturer's issue, I am sure Boeing will issue service bulletin, and more airlines will be affected.
2. AFAIK - CX 747s came from SQ (as CX is so cheap not to buy new planes). So it may suggest that the aircrafts may overused.
3. Maintenance issue - it is not the first recent incident regarding CX aircrafts.
In relation to no. 2, that is plainly incorrect. CX has only bought 3 pax 744's from SQ 2nd hand. The others are new builds (with RR engines) from Boeing. It should be noted that a couple of the SQ birds are younger than the oldest of CX's RR 744's (though I am unsure as to cycles).
These things happen with 20 year old planes, look at QF's 744's and the issues they've had.
