## Discrepancy

DURING FINAL APPROACH TO THE HOSPITAL IN LOVELAND CO, THE CREW REPORTED THE SMELL OF BURNT RUBBER. AFTER LANDING, THE PILOT INVESTIGATED AND FOUND THE A/C COMPRESSOR BELT SHREEDED. HE ALSO NOTED THAT THE DAMAGED A/C BELT CAUSED SIGNIFICATE DAMAGE TO THE HYRDAULIC BELT THAT IS IN PLACE RIGHT NEXT TO IT. THE HYRDAULIC BELT HAD 50% OF THE BELT RIPPED APART FROM THE A/C COMPRESSOR BELT. MAINTENANCE ARRIVED AND REPLACED THE HYDRAULIC BELT AND MEL'S THE A/C FOR COMPRESSOR REPLACEMENT ONCE PARTS ARRIVED.
