Narrative:

The flight was conducted at the request of the maintenance department to try and verify a rough running engine condition at certain power settings. I was accompanied by an a&P mechanic from the maintenance shop. We completed a preflight inspection and performed a run-up prior to departing. We noticed no unusual engine performance during the run-up and proceeded with the flight. We requested a departure to stay in the pattern for a maintenance check flight. We were then assigned a runway departure and instructed to flew east before turning back to orbit the airport over the runway using right traffic. After orbiting the airport 3 times; we called the tower to request a landing. We were over the runway in the upwind traveling north and requested a full stop landing on another runway. The tower came back with an instruction to turn left [then join] final for runway 10. Before making any turns; I requested from the tower to clarify the instructions as I had heard them initially did not make sense. The controller reissued instructions to turn to fly to [a local road crossing]; then enter a left downwind for runway 10.I proceeded to fly the new instructions and entered a left downwind for runway 10. Approaching being abeam the tower; the controller issued an instruction to remain east of alpha taxiway and cleared to land on runway 10. I pulled the power to idle and set up for a short approach. The aircraft touched down [and] I proceeded to apply braking to get the plane slowed down. The brakes became locked up and the aircraft began to lose directional control. At this point; the aircraft stuck one of the runway end lights. We notified the tower that we had struck the light and advised that we could move the aircraft off the runway to the taxiway. When the aircraft started moving; we noticed that there was a flat tire. We notified the tower of this and proceeded to shut down the engine and secure the aircraft.
