Narrative:

During the ILS 10 into stt, the flight crew experienced a propeller overspd on the #2 engine. The surface wind in stt at XA53Z had been reported 070 degrees at 19 KTS gusting to 26 KTS. The crew was issued a low level windshear advisory and experienced +/-10 KTS and moderate turbulence below 2000 ft during the approach. The failure occurred after the completion of the before landing checklist at approximately 800 ft AGL. The #2 acw generator fault light illuminated. During the failure, the #2 np was noted above limitations with an associated torque indication. After executing the go around, the crew referenced the manual for the np over limit checklist and completed the checklist. Due to the windshear and moderate turbulence on approach, the crew elected to return to sju single engine in lieu of a single engine approach to stt. The crew advised the flight attendants and informed them about the situation so they could be prepared. The passenger were also informed. We returned to sju and landed safely.

Title: AN ENG WAS SHUT DOWN ON APCH. PLT ELECTED TO DIVERT TO ANOTHER ARPT DUE TO UNFAVORABLE WIND CONDITIONS.

Narrative: DURING THE ILS 10 INTO STT, THE FLC EXPERIENCED A PROP OVERSPD ON THE #2 ENG. THE SURFACE WIND IN STT AT XA53Z HAD BEEN RPTED 070 DEGS AT 19 KTS GUSTING TO 26 KTS. THE CREW WAS ISSUED A LOW LEVEL WINDSHEAR ADVISORY AND EXPERIENCED +/-10 KTS AND MODERATE TURB BELOW 2000 FT DURING THE APCH. THE FAILURE OCCURRED AFTER THE COMPLETION OF THE BEFORE LNDG CHKLIST AT APPROX 800 FT AGL. THE #2 ACW GENERATOR FAULT LIGHT ILLUMINATED. DURING THE FAILURE, THE #2 NP WAS NOTED ABOVE LIMITATIONS WITH AN ASSOCIATED TORQUE INDICATION. AFTER EXECUTING THE GAR, THE CREW REFED THE MANUAL FOR THE NP OVER LIMIT CHKLIST AND COMPLETED THE CHKLIST. DUE TO THE WINDSHEAR AND MODERATE TURB ON APCH, THE CREW ELECTED TO RETURN TO SJU SINGLE ENG IN LIEU OF A SINGLE ENG APCH TO STT. THE CREW ADVISED THE FLT ATTENDANTS AND INFORMED THEM ABOUT THE SIT SO THEY COULD BE PREPARED. THE PAX WERE ALSO INFORMED. WE RETURNED TO SJU AND LANDED SAFELY.
