RP:-
A combination of unforseen events may, or may not, have caused the accident.
Were the events not 'foreseen' by the Airworthiness Regulations? Did they not forbid the passing of fuel lines joined by couplings through a dry bay that included a source of ignition? Wasn't that the situation with XV230? Wasn't it therefore unairworthy? So how was the coroner being disingenuous?
Pot calling kettle black?
