Summary
Investigation of a crane recertification incident aboard Noble Stanley Lafosse examines brake and sprag-clutch failures during load testing. A water bag descended uncontrollably and hydraulic fluid escaped through failed test ports. Findings identify overload-protection configuration, inadequate training and deficient testing instructions; BSEE made no recommendations at that time.
