Avianca Flight 03

Avianca Flight 03 was a passenger flight from Cartagena, Colombia to Bogotá, Colombia that crashed on January 14, 1966. After takeoff, as the aircraft reached 100 ft, it stalled and crashed into shallow water. After a 14-month investigation, engine failure was found to be a possible, but unproven, cause. Poor maintenance and inadequate inspections were also suspected.

Aircraft
The aircraft involved was a Douglas C-54, the military version of the Douglas DC-4 produced during World War II, registered HK-730 to Avianca. The aircraft involved was produced in 1944; because of military needs, it was equipped with larger fuel tanks, which allowed for intercontinental passenger flights.
