@SNI
With some interest I am following your comments concerning the "Crash worthy" fuel tanks.
Working on EC155 for quite some time, I never heard anything on this "crash worthy" tanks.
So based on your comments, I have checked the SB/MODS/FLM and Type certificate and can not trace any reference to these tanks. I even checked out the original Bristow order for the EC155 that now operate for Shell, without any trace.
Could you please share more information concerning these tanks?
Regards,
Mark
