Past participle of “flaw”

According to Wiktionary, the past participle of "flaw" is flawed, and flawn is not mentioned as being a valid alternative. However, the past participle of "draw" is drawn. I know that Modern English is irregular with regard to many forms and conjugations (for better or worse), but at first glance it is logical that the past participle form should be flawn, and not flawed. In short, what is the correct conjugation of the past participle for the verb flaw?
