Narrative:

#2 engine N2 dropped to 1/2 scale first, followed by change in engine noise, then it went to zero, so we immediately shut down the engine and proceeded to the nearest airport (btr) which was about 20 mi away. We did not have any problem whatsoever to find the airport and, of course, ZHU was with us all the way down. We landed at btr and notified the dispatch. Callback conversation with reporter revealed the following information: the reporter stated the cause of the engine loss of power and complete loss of engine oil was the fan bearing seal failure.

Narrative: #2 ENG N2 DROPPED TO 1/2 SCALE FIRST, FOLLOWED BY CHANGE IN ENG NOISE, THEN IT WENT TO ZERO, SO WE IMMEDIATELY SHUT DOWN THE ENG AND PROCEEDED TO THE NEAREST ARPT (BTR) WHICH WAS ABOUT 20 MI AWAY.
