There was never a body recovered, or positively identified plane wreckage found from her final trip, but in the unlikely event that she did survive, she would now be 113 years old. As there would be only a handful of 113 year old people alive now, much less any of them being famous aviator pioneers, I would surmise that she is dead.
As an aside, there cannot be too many people still alive who were alive when the first powered flight was made. Certainly it is unlikely any remember the time as they would have too young. Soon, everybody alive, will have been alive during the era of powered flight.
For English learning, your question would have been better phrased as "Does anyone know if Amelia Earhart is already dead?"
