Aircraft; Human Factors; Procedure
First flight in this aircraft after being released from Maintenance for a speed brake rigging problem. Trims were all adjusted for neutral settings prior to departure. Immediately upon rotation aircraft rolled hard to left; it took immediate and concerted right aileron and rudder to maintain wings level flight. Verified position of trims at neutral position. Trimmed aileron approximately half way to right stop and rudder several clicks to the right to achieve straight and level flight. Aircraft flew normally from this point. Landed a few minutes later. Straight and level trim settings were outside parameters for normal takeoff. Wrote up aircraft for maintenance action. This is the 4th write up for roll control surfaces in less than a month. This could have easily ended up disastrously.I am not comfortable flying this aircraft until checked out by qualified test/Operational Check Flight (OCF) pilot. Also; there should be a policy in place that any time control surface rigging is adjusted or corrected then a flight by a qualified test pilot/OCF pilot should be performed before releasing the aircraft to the line pilots.
CE680 Captain describes roll control problems at lift off after accepting an aircraft from Maintenance that had had work done on the speed brake/spoiler system. Half of the maximum possible aileron trim is required to trim for wings level flight. Flight diverts to a nearby airport.
