Aircraft
I was cleared for takeoff and for a left downwind departure by Tower. After initial climb and after crosswind/downwind departure I was going to meet up with another aircraft southwest of the airport. Tower asked if I had the other aircraft in sight; and I responded 'affirmative.' Tower told us to contact ZZZ Tower; as that was our destination. I changed the frequency in my radio but had not contacted ZZZ Tower yet. Shortly after that I thought to myself 'If I'm going to catch the other aircraft; I better speed up.' However my hand was still on the throttle; and the throttle was pushed all the way in. I looked at my manifold pressure gauge and was only indicating 20 inches of manifold pressure. I jockeyed the throttle a few times with no change in engine power output or manifold pressure. At this time I was about at a 45 for left base for a landing at ZZZ. I flipped the frequency back to ZZZ Tower and requested a 'Priority Landing; please!' That was obviously granted. I made a turn for the numbers and had enough speed to lower the landing gear and two notches of flaps. On final approach I glanced at manifold pressure gauge and saw 15 in Hg. I landed in the middle of the touchdown zone and on centerline. As I cleared the reverse high speed runway exit my prop came to a stop.An hour later my mechanic arrived and removed the cowling and confirmed a throttle cable breakage.
C210 pilot reported a return to departure airport after noticing loss of power due to broken throttle cable.
