Landing
During an ILS approach, the pilot executed a smooth landing. Shortly after touchdown, the airplane began to weather vane to the right.
Loss of Directional Control
The pilot lost directional control, and the airplane departed the runway to the right side.
Runway Excursion and Damage
After leaving the runway surface, the airplane collided with a runway light. The impact caused the nose landing gear to collapse.
Pilot's Account
The pilot initially stated he could not recall applying any aileron or rudder input before the excursion. He later recanted this statement in the Pilot/Operator Aircraft Accident Report.
Mechanical Examination
An examination of the brakes, airframe, and flight control systems revealed no evidence of a precrash mechanical failure or malfunction.
