On November 10, 2015, AAL 953 enroute to Buenos Aires declares an emergency shortly after departure from KJFK. The flight returned to KJFK and performed an overweight landing. The flight crew stated that the problem had to do with the radome; something had come loose and was banging against the aircraft. The flight landed safely without incident.
It's interesting to note that NY Tracon activated their final approach frequency (132.4) just for AAL 953...it was otherwise not in use at the time.
