Summary
BSEE reports synthetic-base mud discharge following an LMRP H-4 connector integrity failure and additional connector bolt failures. Preliminary evidence identified hydrogen-embrittlement-related stress corrosion cracking as a contributor, with improper electroplating treatment a possible cause. The alert calls for affected-bolt identification, independent certification and vendor quality-assurance reviews, including heat-treatment compliance.
