well after having flown about 6000 hours on a lynx..with GEM.. there is no connection between a max. contingency check and sloppy cyclic and aircraft vibraton.
Max. cont checks..never fail.. you just reach a max value.. either TQ, or NH or T6.. aircraft vibration... depends on your speed and good vibration analysis. 96 % Nr with max cont. better that you check something else...
sloppy control on a lynx at 10.000 feet ... not at sea level even with max. cont.
