What was found
(CAN) PERFORMING A 1000 HOUR / 5 YEAR INSPECTION ON CARGO HOOK SWING FRAME ASSY. THE CARGO HOOK AND LOAD CELL WERE SENT OUT FOR O/H TO THE MFG. WE SENT THE FRAME AND OTHER PARTS FOR NDT INSPECTION WHICH WAS NOT A REQUIREMENT IN THE ICA DOCUMENTATION BUT WE WANTED THE EXTRA INSURANCE THAT NOTHING WAS DEFECTIVE AS THE VISUAL INSPECTION REVEALED NO DEFECTS. THE NDT INSPECTION REVELED CRACKS AT ALL 4 WELDED CORNERS OF THE SWING FRAME WELDMENTS ASSY. THE PARTS WERE SENT BACK TO THE MFG FOR A SECOND OPINION AND THEY WERE DETERMINED TO BE CRACKED AND WITH NO APPROVED REPAIRS IN PLACE THEY WERE SCRAPPED. THE ACFT IS PERFORMING A LOT OF EXTERNAL LOAD OPERATIONS.
