Not even four crews per flight now....
The reason why Bristows were never seen to have these kind of 'foul ups' is that they paid lip service to issues like WTDs, readiness states etc (RS15 with a gearbox on the hangar floor?)
The issue is, with a recent change from ninteen to twenty-four hour duty period, most crews are over their 2000 hour limit. The question is are they legal to fly and in the event of an accident, would they be covered or hung out to dry?
