On May 4, 1997, about 1850 central daylight time, a Cessna 182P, N1530M, registered to Markat Inc., operating as a 14 CFR Part 91 personal flight, crashed on rollout at Mobile Regional Airport, Mobile, Alabama. Visual meteorological conditions prevailed and an IFR flight plan was filed. The airplane sustained substantial damage. The private pilot and one passenger reported no injuries. The flight originated from New Orleans, Louisiana, about 1 hour before the accident. The pilot stated he was cleared for an ILS runway 32 approach, and canceled IFR before landing. The wind was down the runway and the touchdown was described as smooth. The airplane weather vaned to the right, he lost directional control and the airplane went off the runway to the right. He could not remember if he applied any rudder input before going off the side of the runway. The main landing gear collided with a runway light, and the nose gear collapsed after going off the runway. The pilot stated in the NTSB Pilot/Operator Aircraft Accident Report that he applied full right aileron and left rudder. Examination of the airplane by a fixed-base operator revealed no evidence of a precrash mechanical failure or malfunction of the brakes, airframe or flight control assembly. Review of weather information obtained from Mobile Regional Airport, Mobile, Alabama, for the time of the accident revealed no recorded record of turbulence, downdrafts, windshear or gusts, and the wind was 010 degrees at 9 knots.
