TSB Report
And again as with the S76 Tail Rotor control failure ( saving weight with leave the centering quadrant out) and the 214 ST crash ( the pilot switched of one inverter the standby inverter was not synchronised needed a few extra wires) root cause of the accident is not addressed . Root cause, design engineering failure !
I vote for six steel bolts and move on to the next problem that may occur, what els is lurking to take the (or any) machine down.
