On page 1-2, it says that; “A database was developed that includes details of 65 large engine uncontained events. The database spans the period from November 1961 through the present. The primary sources of information were private sector engine companies and airframe manufacturers…The 65 events in the database are not merely a representative selection of the data but the only events with sufficient information to conduct the type of analysis herein. There are many additional fan blade and turbine disk events that are not in the database because of a lack of detailed data.”
From data taken from Service Difficulty Reports and NTSB records, there are over 167 GE failures including 67 uncontained failures from 1971 through April 2010.
More than half have no cause given. More than 8 have occurred in 2010.
The most detailed reports come from the NTSB’s records of two CF-6-80s, which utterly destroyed 767s on the ground on US Air in 2000 and on American June 2006 described in the NTSB Safety Recommendation Letter A-06-60 through –64 and A-00-212-124 . Links >
