I remain perplexed as to how this was missed during the airframe fuel system & engine certification and design paths and why the problem has remained hidden until now.
. Good point. Missable perhaps because the certification and design used familiar and well-accepted principles, and the BA038 flight probably strayed into new territory.
I wonder if we were previously on the edge of an (as-yet undefined and only just realised) envelope and have stepped outside that envelope with this combination of aircraft, route, cold soak, fuel, testing, and specification. Not just an issue specific to the manufacturer or supplier, but rather a global issue with global consequences for the present system. Which includes engine and airframe manufacturers, and certification authorities (and not to forget the operators and crew).
Don’t Hang Up hinted at the new territory. I think it is wider than BA038 and similar operations. The new territory encompasses specifications, design and test methods, and presenting the biggest challenge of all - it questions how we will deal with the much bigger issue of the new bio-fuels. There is much work to be done (as PG said). And I think we are only at the start.
PS - Pinkman picked fuel as the cause of BA038 about a year ago, and Hotdog (The Reverend) has been contributing wisdom here for many years.
