Hi guys,
The F/O was and is still a friend of mine's. His old brother too.
They were flying this company for a few months.
The F/O is now flying on ATP in europe, and his brother on A320 at Qatar Airways.
The Captain was put in jail because he was advised before the flight of this gearbox HS. The F/O wasn't, but him and his brother had a lot of issues leaving Gabon.
