The Merriam-Webster Dictionary, published since 1828, defines "gauge as a measurement (as of linear dimension) according to some standard or system, such as the distance between the rails of a railroad." Merriam further notes "variants: or less commonly gage" Same meaning, but gage is less commonly used; not archaic, just less commonly used.
Might the NTSB analysis and report be a legal document that might find it's way into court? Could the word "gage" be appropriate or even required in a legal application? Might it be an engineering term? It does seem to be gramatically correct.
