Thanks for explain the EC155 capability again. Having seen the comments on past kidnaps in Nigeria I'm sure having 25 minutes tested would be more reassuring that just 11 when flying over the delta.
It does go to show that some OEMs have been able to take an earlier design build it into an bigger airframe and still expand the loss of lube resilience.

It is well worth reading the
http://www.pprune.org/rotorheads/163...perations.html thread (as mentioned by TSB in their report) for the period between the catestrophic MGB test in early August 2002 (done the conventional way with just residual oil) and the December 2002 FAA certification (with the bypass added). There is a hint of the schedule pressure there.
