What we don't know is if the maintenance performed corrected the imbalance and subsequent vibration in the pedals. Until they determine the failure sequence of the T/R Assy, it's quite possible those engineers did exactly as they were required to do. As to signing off something then have a fatal accident, I would not wish that on any mechanic/engineer as it is the most sickening feeling out there. Sometimes catastrophic failures hide behind the most routine types of discrepancies....
