This needless and avoidable accident should send out a clarion call to the military aviation community of the importance of a fully functioning Air Safety System and what can happen when there isn't one, as then, and as now.
This seat did not have a Safety Case. If it had then a continuous auditing process would have highlighted the possibility of the drogue shackle nut being overtightened as a result of the improper use of an RTI requiring the nut to be unfastened and refastened on the line every 50 hours. It would also have highlighted reports of the SPH pin being inserted leaving the seat live, and for that matter the ease of misrouting the crotch strap through the SPH, and measures would have been taken to alleviate all of these issues.
There was no Safety Case though, and the aircraft RTS was therefore illegal. There was no overview of this vital safety component by the Regulator, rather all was left to the airmanship of the pilots and the professionalism of the ground engineers. The Regulator should be in the dock in my view, attempting to defend the indefensible. Unless and until it is, then needless and avoidable accidents will simply carry on happening...
