Even though AirRabbit's whole string of posts is an exercise in ignorance I'll chime in one last time for the sake of spreading valid knowledge:
The 8900.1 is the guiding document for the FAA, it is law to the FAA inspectors as much as the FAR is law to aviators. And yes, FAR is an official designation in the 8900.1 for use in FAA documents:
8900.1 Volume 1, Chapter 1, Paragraph 1-46, Table 1-1 contains all FAA abbreviations, which includes:
"FAR Federal Aviation Regulations"
The abbreviations on that page are in alphabetical order.
And as an aside, the FAR (Federal Acquisition Regulations) are Title 48 of the Code of Federal Regulations (CFR), while the FAR (Federal Aviation Regulations) are Title 14 of the Code of Federal Regulations (CFR). So technically both are "CFR" by AirRabbit's argument.
