Well, I'm not familiar with the type but I'll take a wild guess that even a bearingless head needs to be inspected from time to time, presumably even during preflight. Also note that while the blades are bearingless, the flight controls are not.

On the other hand the fairing itself probably requires maintenance. They said it was rather complex to adjust the gap below the head fairing. If this is not done properly, the aerodynamical effect might even be negative compared to no fairing at all...
