A Fokker 100 passenger jet, PH-KLC, sustained substantial damage in a landing accident at GenŠve-Cointrin Airport (GVA), Switzerland. All 95 passengers and five crew members survived. Flight KL321 had departed Amsterdam-Schiphol International Airport (AMS) at 13:06 local time on an international flight to GenŠve-Cointrin Airport (GVA). The flight was uneventful. At the end of the approach in the automatic mode, the aircraft landed gently on runway 23. Immediately after the aircraft developed severe vibration, which increased causing the fracture of the left main landing gear leg. The left wing struck the runway and the airplane came to rest at the left runway edge. CAUSE: The accident was due to the rupture of the left main landing gear after the occurrence of severe vibration. Contributing to the accident: – Insufficient damping of the main landing gear and its connection to the structure as a dynamic system; – Random, simultaneous occurrence of factors that caused a resonant oscillation of the left main landing gear.
