ripped,
I would have sent this privately as it does not directly relate to this accident but I wanted to share. I did fly the 601-3A for about 7 years but this is not about that. It's about RAT's and HMG's. Again not related. My younger brother flew for United. About 20 years ago on a EZE-MIA night flight they lost electrical power south of Columbia. B767 ETOPS. They were unable to get RAT (I think that's what the 767 has, if not HMG). System design prevented auto deploy (apparently no manual deploy) because the system sensed normal AC power from both gen's. Problem was the ground. Both the AC and DC system share the same grounding bracket which had a little bit of corrosion breaking the ground. Google Cast BP Witcher and United Airlines. It was flight UAL 854/EZE-MIA/13 April 2004.
