Lessons Learned - continued
- Following the accident, the FAA conducted a Critical Design Review (CDR) to address potential DC-10 safety issues related to CF6 engine fan blade fragment ejection. The CDR put considerable focus on fan blade fragment ejection and its potential hazards to the aircraft for a specific fan blade problem that was resulting in frequent fan blade failures in revenue service. This review may have been too focused on a specific revenue service problem and did not address system level threats such as loss of the aircraft's hydraulic system due to uncontained engine debris. The investigation needs to be broad enough to look for other possible accident precursors.
