Incident Overview
A non-instrument rated pilot conducting a night flight encountered unexpected ground fog during the landing phase, resulting in a collision with runway lights and subsequent landing gear failure. The pilot had received a weather briefing before departure and was advised that Visual Flight Rules (VFR) flight was not recommended.
Sequence of Events
While arriving at the destination airport at night, the pilot circled twice over the airport and observed that the runway lights were clearly visible. He then entered the traffic pattern to land. According to the pilot, just before touchdown, he experienced a momentary, unexpected white-out. Reports indicate that a thin arm of ground fog was encountered. During that brief moment, the aircraft drifted to the right over the runway lights.
Damage and Consequences
The aircraft sheared off two runway lights. The right main landing gear collapsed when the wheel struck a concrete slab at the base of a runway light.
Pilot Background and Conditions
The pilot held a non-instrument rating. The flight was conducted at night, and weather conditions included ground fog in the vicinity of the airport. The pilot had been informed that VFR flight was not recommended, but proceeded with the flight.
