While not doing any specific research on the topic, I maintained that
there was no requirement (for part 91) for paper charts to be on board
(other than the "all available information" requirement). Just that
any charts you had on board had to be current.

I know of no regulation prohibiting the carriage and transport of
outdated charts.
