Field Assist Drawings (FAD)
Field Assist Drawings are part of Delta’s Total Support Solution (TSS). We add images of all field supports on original ISOs with each shipment. Our FADs help Material Control issue the right material and help craftsmen see where supports are to be installed in the field. We take it one step further and identify all “Tack-Only” supports for safety in handling and to ensure that final field welds are not missed.
