Fullmetal no longer has weekday rerun airings, however new episodes do air and repeats hours later on Saturday nights. It will be airing at 12am EST, and will start back up with episode 41, Holy Mother.
Looks like they've also listed the episode titles for 42 and 43.
Fullmetal Alchemist 41 - Holy Mother
Fullmetal Alchemist 42 - His Name is Unknown
Fullmetal Alchemist 43 - Stray Dog
Do note that the titles for 42 and 43 are subject to being different than the actual title of the episode like previous episodes have had.
Again, new FMA episodes on [as] at 12am EST on Saturday nights, with a repeat airing at 3am EST.
11pm and 2am for Central, and 12am and 3am for Pacific time zones. Not gonna bother with Mountain, Hawaii or Alaska. *cough*
