Magneto – Optical (MOI) is a portable system that produces images showing irregularities and discontinuities in the inspected material. Rivet holes, cracks, and subsurface corrosion are readily visible. The MOI uses eddy current imaging, which is a technology which allows nondestructive method of inspection of most ferromagnetic and non-ferromagnetic metals.
Apex Inspections is one of the few companies that acquired a MOI unit for Boeing Aircraft inspections. We have utilized the MOI on Cessna Citation Lap seams and during SID and heavy “C” inspections on the DC-10 and MD-11 aircraft. Using our 3D headset we are able to find the defects that are sometimes overlooked.
