Just because an FSAP was filed doesn’t necessarily mean the event was sole source or self disclosed. Program was never designed to be a get out of jail free card after other entities became aware of the incident. For example, if you go out and cause a runway incursion and get a pilot deviation you can’t just file an FSAP and the whole thing automatically goes away. They just can’t use the content of the FSAP against you and your self disclosure may cause the powers that be to let the ERC counsel you instead of turning it in to a bigger deal. No idea the specifics on this event but the fact that one example being in an FSAP isn’t surprising or necessarily egregious to me.
