HH-60G tail rotor 3° bias degradation
Greetings! Question for the engineers: what would cause a 3 degree bias to go out over time? Main rotor rig is in check, tail rotor rig is in check, all pins slip fit, cable tension is fine, but the bias when checked is out by between half and a full degree around the whole tail rotor. And yes, it was rigged and biased correctly the first time. The time frame I speak of its just over a year. Thanks!
