Narrative:

Initiated snap roll in the active aerobatic box at 3;000 AGL and the left rudder cable failed resulting a loss of rudder control. Proceeded directly to enter left traffic to land. On landing; plane yawed left and I used left brake for directional control. Left brake locked up resulting in a prop strike. No substantial damage and no one was injured.I performed a thorough preflight prior to departure which included checking rudder cables and attachment points and did not notice any fraying or damage to the rudder cable. The area where the cable snapped is enclosed in an 'south' shaped tube which requires cable removal in order to inspect and is normally only inspected by a mechanic at the annual condition inspection.
