cockney...the bolts would be in tension, not shear...
given that about 150 batteries have been replaced, and the issues, dont you think routine inspection would be in order? So those 52 bolts times 2 boxes..
The test noted that moisture buildup inside the existing box may have been a cause of the short....what is to prevent that in this box?
What about the other Li battery, the backup for the avionics?
I see that most of the news regarding test flights beginning this week is now gone....perhaps the NTSB warning from their lead counsel to Boeing had something to do with that..
