You're assuming of course that the FAA was not already considering this, and had no idea whatsoever that the case might affect some people other than the principles in the court case. It's possible of course, but not very likely. I'd bet good money the lawyers at the FAA were already looking into all this. It's what they're paid for, and surely the ramifications of the case couldn't have escaped the attention of everyone at the FAA while simultaneously being so troubling to AOPA and EAA. It's extremely unlikely the letter from AOPA/EAA caused all this.
