A Beechcraft B200 Super King Air experienced a significant landing accident at San Carlos de Bariloche International Airport in Argentina. The aircraft landed in poor weather conditions, including low clouds and reduced visibility, resulting in a nose landing and damage to the nose and propellers. The aircraft executed an instrument approach to runway 29 using ILS, and air traffic control did not provide track surface conditions. The crew had visual contact with runway 29 at 270 feet, 32 feet above decision height. The aircraft?s landing configuration involved deploying full flap, which could have influenced control during the flare. The aircraft impacted the runway approximately 1375 meters from the headland, displaced from its axis to the left, and was impacted by snow and ice on the edges of the runway. The left propeller struck the snow bank.A Beechcraft B200 Super King Air experienced a significant landing accident at San Carlos de Bariloche International Airport in Argentina.
