On March 31, 1991, the pictured Vickers Viscount 745D HK-1708 of Intercontinental de Aviación was damaged beyond economic repair while on a flight from El Dorado International Airport in Bogota to Gustavo Rojas Pinilla International Airport. Both artificial horizons failed in turbulence at 16,000 feet (4,900 m). Control of the aircraft was regained at 4,000 feet (1,200 m) and a successful emergency landing was made at Olaya Herrera Airport, Medellin. The lower main spar was found to have cracked. The aircraft had previously suffered a gear collapse on February 14, 1988.
