An Atlas Air Boeing 747 (N534MC) suffered an uncontained No. 1 engine failure while climbing through 400 feet after takeoff. The aircraft leveled at 817 feet and the crew declared an emergency. Fuel was dumped and the plane returned to Guayaquil.
When returning, the no. 1 engine turbine part was lost over Guayaquil. The aircraft landed safely. The Boeing freighter was on a flight for Lan Chile on the route Santiago de Chile-Guayaquil-Miami. Investigation revealed an airduct failure in the area of the 7th stiffener. The airduct machined into the fan mid-shaft, which separated resulting in the uncontained failure of the engine.
