What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot stated: Monday 5/19/2014 at about 2:30 pm. N9316K at arb weather was clear, wind was reported as out of 180
After preflighting in my hangar in the NE "tees", I moved to the run up area and did a normal run up.
After I was cleared for take off I moved into position on runway 24 and applied power. The aircraft began to turn left and my control inputs would not straighten it out. I immediately pulled power as the aircraft exited the runway into the grass left of the runway. My left gear leg must have encountered a runway light as the fairing on the left gear leg was damaged. After stopping I was able, with clearance from the tower, to taxi back to my hangar. During the taxi back the aircraft seemed to be normally controllable.
I suspect that the left brake stuck or the tailwheel did not lock after my turn onto the runway.
An aircraft log entry was made stating; checked the tailwheel and brakes for proper function. Aircraft taxi tested and test flown, all systems function normal.
