2、M) with the LH2 carrier plate. Due to mechanical design the interface connection is very poor. The LO2 interface is identical and has experienced leakage in the past. Undetected leakage could cause a major fire resulting loss of life or vehicle.Lesson(s) Learned: Lack of adequate LH2 Leak detection
3、at the 8 inch T-0 flexhose QD/interface could result in fire.Recommendation(s): Design/install a new leak detector sensor console to accommodate additional leak detectors.Evidence of Recurrence Control Effectiveness: N/ADocuments Related to Lesson: N/AMission Directorate(s): N/AProvided by IHSNot fo
