I was in full agreement until the last paragraph. The Safety Assessment called for by FAR 33.75 is not easy to do . If it were we would never have any unpleasant surprises. In general the discipline is a pretty good coarse filter and certainly better than nothing.
And we fought long and hard to retain the rigour of European Requirements. So there is no such thing as JAR 33.75. It is JAR E, or in this case I believe something called CS-E 515.
bearfoil - Could you please state in simple terms the failure progression you are postulating? Your thoughts are very interesting but I sometimes have difficulty in following them.
Do you think there was not an oil fire?
