During the landing approach on an instructional flight, the certified flight instructor (CFI) initiated a go-around and experienced restricted elevator control movement. The elevator control became partially jammed in a nose low and then a nose high position. Roll and yaw control was not affected. Using considerable force, the CFI maintained airplane control and landed without additional incident. Thereafter, the airplane was inspected. Evidence of mechanical binding to the elevator pitch control cables was noted. Specifically, a screwdriver was found wedged between the nose gear actuator retract rod and the elevator control cables beneath the forward spar cover, between and under the pilots' seats. When the nose gear retracted, the nose gear actuator retract rod moved the screwdriver against the elevator control cable resulting in binding. Upon removal of the screwdriver, the elevator operation was normal. Two days prior to the incident, a contract mechanic had performed maintenance on the airplane. The maintenance required taking off the forward spar cover to allow removal and installation of a flap motor gearbox assembly and flap flex drives. Since this maintenance, the airplane had been operated 5.8 flight hours.
Probable Cause: During landing approach, mechanical binding of the elevator control cable occurred due to a contract mechanic's improper maintenance.
