Members of the Delaware National Guard's 166th Airlift Wing Aircraft Maintenance Squadron work to maintain and complete "ISO" Inspections on the DEANG's fleet of C-130H3s.
The isochronal periodic preparation and inspection, also known as ISO Inspection
are a vital part to ensuring operational aircraft safety and gives an in-depth vigorous inspection to every component of the airframe.
Thank you to all of our Air National Guardsmen that go above and beyond to make the 166th missions possible.
