Here you can read more about it: http://troygilbert.com/2009/05/loading-flex-based-swfs-in-as3-only-swfs/

Here is the code for loading the flex swf:

var loader:Loader = new Loader();
addChild(loader);
loader.load(new URLRequest("my-flex-app.swf"));
loader.addEventListener("mx.managers.SystemManager.isBootstrapRoot", systemManagerHandler);
loader.addEventListener("mx.managers.SystemManager.isStageRoot", systemManagerHandler);

function systemManagerHandler(event:Event):void { event.preventDefault(); }
