You reckon the Apache Rotor system and flight control linkages might be susceptible to the same sort of thing?

Thinking "Pitch Cone Coupling" which is a section of the AH-1S Flight Manual contained at the Link below.

The AH-1G/S used the 540 rotor system, as did the UH-1C/M. Pitch cone coupling was a feature of that system due to the flexure plate. The AH-64 uses a conventional articulating system.
