I wonder to what extent that reasoning could be used on other non-US accidents. Even if the AF447 aircraft had Rolls-Royce engines, the placard on the outside of the FDR chassis clearly says "Honeywell". Could the NTSB participate in an accident investigation for the sole reason of being the state of manufacture of the very same recorders that potentially hold the answers to solving the cause of an accident?
