During a routine training flight; while doing unusual attitudes the ailerons momentarily locked up. In order to break the ailerons free it took a lot of pressure. I advised Air Traffic Control of the situation and reported that I was not declaring an emergency at that time but that the situation was urgent. Upon touchdown and taxi in to the ramp; I was met by emergency crews who needed various information. Maintenance inspected the airplane and determined that lock up in the controls was caused by the aileron linkage behind the dash was getting caught on a fuel pressure gauge line. Maintenance repaired the defect. In hindsight; the only thing I would have done differently would be that I would declare an emergency in order to be ATC's priority.
BE55 instructor pilot reported the ailerons locked up and it took considerable effort to break them free. Post flight inspection revealed the aileron linkage was caught on a fuel pressure gauge line.
