## Discrepancy

ON ARRIVAL DESCENT TO 11,000 FT THERE WAS A NON-TYPICAL ELEC SMELL OF STRONG ODOR.  SMELL WAS NEARLY GONE 15 MINUTES LATER AT TOUCHDOWN.  NO VISUAL SMOKE WAS EVIDENT OR INDICATED.  TROUBLESHOOTING REVEALED THE CABIN BLOWER FAN ASSEMBLY FAILED & A WIRE WAS BROKEN AT THE SOLDER JOINT WHICH WAS ARCHING & WAS MOST LIKELY CAUSE OF SMELL.  A NEW BLOWER FAN WAS INSTALLED IAW SB560XL-21-25 AS WELL AS COMPLIED WITH ENGINEERING DLP-560XL-21-00004 WHICH INSTALLS A NEW DIODE ATTACHMENT PROCEDURE, WHICH SHOULD CORRECT POSSIBLE FUTURE ARCHING IN THIS AREA.  THE SYS CHECKED PROPERLY & THE ACFT WAS RETURNED TO SERVICE.
