On January 19, 2026, about 1303 mountain standard time, a Cessna 500 airplane, C-GJVK, was substantially damaged when it was involved in an accident at Great Falls International Airport (GTF), Great Falls, Montana. The pilot and passenger were not injured. The airplane was operated as a Title 14 Code of Federal Regulations personal flight. The pilot reported that during the approach he extended the landing gear and received an unsafe indication for the left main landing gear while the nose gear and right main landing gear indicated down and locked. He then moved the landing gear lever slightly and received a down and locked indication for the left main landing gear. All three landing gear down and locked lights were illuminated for the remainder of the approach. The landing was smooth and as the airplane slowed to about 30 knots, the pilot felt the left wing begin to lower and the left wing and flap then contacted the runway. The airplane veered slightly to the left and came to rest with the left wing over the grass and with the left main landing gear collapsed. Postaccident examination revealed that the airplane’s left wing sustained substantial damage. The airplane was recovered and retained for further examination.
