The FAA must approve all repairs involving structural components on airplanes. NVision has a wide range of 3D scanning systems available for aviation work, with ultra-high accuracies starting as precise as .0002”. That is impressive.
Using the HandHeld Scanner, it took NVision technicians about 1/2 a day to scan the part before corrosion was removed and another 1/2 day to scan it after the removal of the defects. NVision then created an inspection report, with color deviation chart, precisely documenting the exact amount and location of any corrosion and associated metal that had been removed from the part. The report was reviewed and approved by the FAA.
I like their tag line, “The Art of Technology.”
