## Discrepancy

WHILE ENROUTE BACK TO BASE FROM SAN ANTONIO, ABOUT FIVE MILES EAST OF HONDO, TEXAS;  MEDICAL CREW REPORTED THE SMELL OF "BURNING PLASTIC" IN THE AFT CABIN.  THE SMELL WENT AWAY AND THEN CAME BACK.  I NEVER SMELLED ANYTHING IN THE COCKPIT.  I ELECTED TO MAKE A PRECAUTIONARY LANDING AT THE HONDO, TEXAS AIRPORT AND CALLED MAINTENANCE. REAR A/C BLOWER WAS FOUND TO BE THE PROBLEM.
