No, actually all it means is that of all the written squawks by pilots of this aircraft involving aileron issues, Lockheed did the work necessary to bird dog the squawks, isolate, identify, and rectify them.
These squawks point to, among others:
Boost pumps. Boost cylinder and piston. Autopilot as required MEL. Chattering Boost Control valve, fluid filtration, pressure relief and piston balance, improved scavenge of passive side, paperwork requirements, better and more frequent inspections, and many more.
It isn’t cute to leave unsafetied a single, non redundant system. But it might not be the correct answer to 706.
