On April 13, 2006, about 1755 central daylight time, a Beech C24R, N1826A, registered to and operated by a private individual, as a Title 14 CFR Part 91 personal flight, veered off the runway during landing in Panama City, Florida. Visual meteorological conditions prevailed, and an instrument flight rules flight plan was filed. The private-rated pilot and three passengers were not injured, and the airplane incurred substantial damage. The flight originated in Macon, Georgia, the same day, about 1720. The pilot stated that he made a normal landing with a left to right crosswind, and the airplane started to turn to the right. He said he applied left aileron, and he was activating the left brake, while also applying left rudder input. He said that none of his corrections seemed to have any effect, and he applied full braking action before exiting the runway. The airplane continued to turn and slide to the right, and it stopped facing the other direction, with the left main landing gear and wing in a ditch. According to the pilot, the right main landing gear tire was flat, and the airplane incurred damage to the left wing, empennage, and left landing gear area. Postcrash examination of the airplane and runway by an FAA inspector, showed that damage to the wheel rim and marks on the runway were consistent with the right main tire being low or flat during the landing roll.
