Pretty much any word, a native speaker can forget to type it.Most of the native errors are spelling mistakes, noun-verb agreements, and things like "they're" "their" and "there," confusing when to use "was" and "were" are common among natives.

In any event, I think "an" and "a" are far simpler to understand for english learners than say the "en," "de" and "à" of french which in many cases seem completely randomly chosen and don't follow a logical "in" or "from" forms. There's this theory of native speaker infallibility, that says native speakers don't make grammatical errors. They do make typo's, tongue slips, and spelling erorrs, and there are often grammar problems when you go back and edit part of a sentence without fixing the rest.
