## Discrepancy

THIS OIL FILTER ADAPTER HOUSING WAS REPLACED AT TAE AEROSPACE IN NOVEMBER 2025. IN OCTOBER 2025, OWNER WAS EXPERIENCING A SLIGHT OIL LEAK FROM THE #1 ENGINE AND GLOBAL MX, CRS 1VUR633D AT KHZL, COULD NOT DETERMINE THE CAUSE. GLOBAL MX REMOVED THE ENGINE AND SHIPPED TO TAE AEROSPACE FOR INSPECTION TO DETERMINE THE CAUSE OF THE LEAK. TAE AEROSPACE DETERMINED IT WAS THE OIL FILTER ADAPTER HOUSING WAS CRACKED AND THEY REPLACED IT. SHOWN ON THE 8130, IT WAS REMOVED FROM A SERVICEABLE ENGINE AND INSPECTED PRIOR TO INSTALLATION ON THE #1 ENGINE. THE ORIGINAL OIL FILTER ADAPTER FOUND CRACKED BY TAE AEROSPACE IS UNKNOWN WHEN IT WAS INSTALLED. THERE ARE NO MAINTENANCE RECORDS SHOWING IT WAS EVER REPLACED SO IT IS BELIEVED IT WAS THE ORIGINAL PART. THE ENGINE WAS SHIPPED BACK TO GLOBAL MX FOR REINSTALLATION, RETURNED TO SERVICE IN NOVEMBER 2025.
