Sort of. Depends on what you mean by "being done". You can only operate the aircraft to 13:00 (or 15:00 if voluntarily extending). But the company can deadhead you or make you sit around for as long they want under FAR117. It is literally unlimited. As long as you're not operating the aircraft. Until you are released you can wind up sitting around waiting to see if the company wants to deadhead you somewhere, waiting for an airplane to get fixed, weather to clear, whatever. The worst part is when you can't get ahold of anyone on the phone because they are in full IROP meltdown and don't even answer the phone. Notice you can't email or text crew tracking either.

But wait! That's where our PWA comes in to finally say when we're done. The ON DUTY ACT/MAX column shows that. Add two hours to MAX and include 30 min postflight - and you've cracked the code. After that time you are not obligated to remain on duty for anything. Can't get ahold of crew tracking now? Go to a hotel. Go home. Wait for them to work through their stack of broken rotations and call you.

Read all about how that is determined in the live contract on the DALPA website. Language highlighted in green is current language, language highlighted in yellow is future changes.
