if the FBI is an authority then it is NOT a fallacious appeal, dipshit
School time for the divebitch:
Fallacious appeals to authority take the general form of:
1. Person (or people) P makes claim X. Therefore, X is true.
(1. FBI says 95% flight 93 recovered. Therefore it is true 95% has been recovered)
A fundamental reason why the Appeal to Authority can be a fallacy is that a proposition can be well supported only by facts and logically valid inferences. But by using an authority, the argument is relying upon testimony, not facts. A testimony is not an argument and it is not a fact."

Furthermore, the FBI is not the expert authority on plane crash investigations.
What a lying sack of rancid rotten menstrual drippings. The FBI is not required to be THE expert (as though there is only one possible expert) on plane crash investigations to be AN authority (especially when working together with the NTSB).
Since when did it become required that the "expert" be the leading expert in order for an expert opinion or assessment to avoid the fallacy of an appeal to authority?
You snake-y slimy dishonest fucking dripping pussies are a thoroughly disreputable lot.
The FBI has developed a pronounced expertise in INVESTIGATIONS generally, you imbecile. And how much expertise IS required, anyway, to conclude that plane crash debris -- constituting less than 100% of the plane itself -- amounts to about 95%? And THAT is the real question, given a VALID definition of the fallacy of "appeal to authority."
If I point to YOU, for example, as an "expert" in brain surgery and cite your opinion that all brain surgery poses an unnecessary and unacceptable risk of the patient contracting syphilis, THEN the complete lack of expertise you have matters. But, when a person cites an ACTUAL expert, then the question boils down to how much expertise is required? YOU have no expertise. The FBI in conjunction with the NTSB has a massive amount of perfectly valid expertise.
I suspect that your actual complaint is not even associated with the alleged fallacy of "appeal to authority." That "complaint" is ridiculous on its face. Instead, I suspect that what you are actually attempting to grunt out is the question of whether (or not) the FBI was being truthful. That issue is entirely distinct from one of credentials.
