This is an interesting logic discussion. :-) Does the term non sequitur apply to correctly formed statements where the conclusion of the statement is incorrect? I would be inclined to agree with TheSpiceIsLife and say no. Because the article is based on limited sources, the article's conclusion about helmet replacement is incorrect, even if it's well-formed.

EDIT: Here's an interesting list of non sequiturs, many of which fit the same pattern as the article. I think loeg is probably right after all.
