Any proper solution would need to explain the problem scientifically and (eventually) come up with a new set of rules both for Fuel Specification(s), for pipework/accessories installations and flight planning and operations.
THEN ALL aircraft, no matter what engine, would need to be checked against the new rules.
Absolutely agree
We need to learn and avoid pointing fingers at persons/organizations and stop throwing stones inside a glass house that we are all inside.
Since it's obvious to me that the industry (regulators, engine and airframers )did not know of this combination beforehand it just happend to be a RR installation that first illustrated the weakeness in all our collected ignorance.
