What happened
During an ILS approach, the pilot was unable to see the runway at the decision height and subsequently initiated a missed approach. Shortly after the missed approach was started, the runway became visible, prompting the pilot to reduce power and attempt a landing.
During the flare phase of the landing, ground fog caused the pilot to lose sight of the runway again. The aircraft drifted to the right of the runway centerline, touching down in a grassy area. As the aircraft slid across the wet grass, it became uncontrolled. The impact and sliding motion resulted in the collapse of the main landing gear, followed by the collapse of the nose gear when the aircraft slid back onto the paved runway surface.
No injuries or fatalities were reported in the accident.
