Corporate Manslaughter?????
Wing bolt missing, maintenance records forged (on good authority) = aircraft not airworthy = aircraft shouldn't be flying = aircraft should not have crashed = persons should not have been killed and injured.
The holes in the Swiss Cheese were lining up long before the accident.
Corporate responsibility for the state of the aircraft and, maybe, corporate responsibility for the accident?
The fact that carb icing may have been the immediate cause of the accident doesn't detract from the fact that the aircraft shouldn't have been on the approach to Caernarfon that day in the first place.
