Hello all, I couldn\'t work out why my last topic for discussion was getting no responses. I now know why! New webpage. Anyway, has anyone ever experienced an engine rollback from a partial or full loss of the ESS AC BUS \'a\' phase circuit breakers (qty - one, two or three) on the 245 bulkhead. There is a note in our flight manual that talks about if a full or partial loss of the ESS AC BUS circuit breakers will or could cause a four engine rollback in torque by 2000 inlbs through a low voltage to the synchrophaser resulting in the speed bias motor reducing speeder spring tension and decreasing blade angle. It also talks about a low voltage to the TD amp resulting in:huh: the valve to take fuel causing a rollback in LSGI and above crossover. And if anyone is using the solid state amplifiers for their TD system, could you make comment if any issues have been encountered. Much appreciated. Cheers, Sideshow.
