Failed GE jet engine in O'Hare fire had manufacturing flaw: NTSB

New York

AN engine on an American Airlines plane that exploded on a Chicago airport runway on Oct 28, triggering a massive blaze, had an apparent manufacturing defect, US investigators say.

A disk within the General Electric Co (GE) CF6-80 engine had an "internal inclusion", meaning some type of foreign debris was embedded within the special alloy designed to withstand the heat and high stresses of a jet engine, the US National Transportation Safety Board (NTSB) said in a statement last Friday.
