Unfortunately our Head of Training doesn't believe in multiple failures even after out double flamout at CIA in November. All TRI/E's scared to give any 'extra' training as it would result in instant dismissal from the training department. Bollox ha?
It has nothing to do with your HoT, or any other HoT for that matter. No aviaition authority accounts for multiple failures otherwise there would be no ETOPs!
They work on statistical probability and the likelihood of a multiple failure and accept that the probability is so low that multiples are discounted.
The fact that 2 occur in 2 months does not necessarily mean that another will happen, or not happen, in N years.
Maybe they will re - examine the probabilities though and suddenly 3 and 4 jets will become popular as ETOPs restrictions build up.
