An aircraft suffered a landing gear failure during touchdown at Sioux Lookout, resulting in significant structural damage and total loss of the airframe without any injuries to those on board.

What happened

The incident occurred during the landing phase at Sioux Lookout. Upon touchdown, one of the landing gear units failed, leading to an immediate mechanical malfunction. The failure resulted in substantial damage to the aircraft structure. Despite the severity of the impact and the resulting wreckage, there were no fatalities or injuries reported among the occupants. The extent of the structural compromise rendered the airframe beyond economical repair, classifying it as a total loss.

Findings
