## Discrepancy

DURING FINAL APPROACH, THE PILOT DECLARED EMERGENCY AFTER PERFORMING A PRECAUTIONARY SHUTDOWN OF THE ENGINE DUE TO OBSERVED HIGH TEMPERATURE.  AN UNEVENTFUL SINGLE ENGINE LANDING FOLLOWED.  POST FLIGHT INSP FOUND A STUCK COMPRESSOR BLEED VALVE (BOV) PISTON AS A CAUSE FOR THE EVENT.  THE BOV WAS REPLACED AND THE ACFT RETURNED TO SERVICE.
