Aircraft
While preparing for takeoff; the Gust Lock would not completely disengage in the Thrust Lever Quadrant; jammed mechanical linkage. Told ATC we would need a minute or so in position and was told to taxi clear of the runway. Maintenance problem; probably unavoidable. Rejected Takeoff (RTO). Flight was delayed.
Reporter stated the Gust Lock control handle only disconnected about half way forward; would not fully disconnect; jamming Thrust lever movements. The Gust Lock did release elevators; but would not disengage in the Thrust column.
A Captain reports the Gust Lock on an EMB-145 aircraft would not completely disengage at the Thrust Lever Quadrant while preparing for takeoff. Crew cleared the runway due to jammed mechanical linkage.
