ActionScript 3.0 :: Event Handler To Remove A Child?

I have two classes in my project - a main class and a fancyText class. In main I create a new instance of fancyText and add it to the stage. Inside fancyText there is a timer that runs and when x time is up the fancyText fades out.

I'd like to know the best way to remove the child from main when the alpha of fancyText hits zero. Should i go down the route of adding a listener to fancyText in main, and dispatching a custom event from within the fancyText class?

I guess i could just check the child's alpha value in main and remove it when the alpha it's zero. But fancyText only gets added in a certain scenario - so i can't check it all the time - which would mean doing something like this:

Code:
...
addChild(fancyText)
checkFancyText = true (assuming a boolean declared earlier)
...
elsewhere in main -

[Code].....

Seems like there are a number of ways to do it - I don't suppose it's possible to remove a child from main from within fancyText class? or is that space cadet talk?
