## Discrepancy

CREW REPORTED HYDRAULIC SYSTEM A LOW QUANTITY DURING FLIGHT FROM TEB TO PBI. CREW FOLLOWED CHECKLIST AND LANDED WITHOUT INCIDENT. UPON INSPECTION, FOUND 2 HYDRAULIC LINES ON THE A SIDE COMPARTMENT CHAFFING. FURTHER INSPECTION REVEALED A STANDOFF WHICH KEEP THE LINES SEPERATED WAAS BROKEN. THIS LEAD TO CAUSING NO SEPARATION BETWEEN THE TWO HYDRAULIC LINES AND CAUSING THEM TO CHAFE.
