The main rotor head hydraulic damper beam has been over tensioned. This would cause
- too much stability and over sensitive controls.
- too much stability and less sensitive controls.
- instability and over sensitive controls.
Explanation from PART66Online
The hydraulic drag (lead-lag) dampers control how the rotor head responds to control inputs and disturbances. Over-tensioning the damper beam upsets the designed damping balance so the head no longer settles smoothly, giving instability with controls that feel over-sensitive. Correct damper tension is needed for stable, well-damped rotor behaviour.
