Arkansas ANG four engine rollback. in C-130 General Posted November 10, 2008 I had two, four engine rollbacks in four years of fly T models...the sad part was it was with the same S/N sync box. We were trained and practiced the malfunction in every sim. On line checks we would have to talk our way thru the procedure and get to the place where we pointed to the sync box and simulated pulling it. I think the Col was blowing crap out his behind.
