The wing of the 728 was a derivative of the "Tragflügel Neuer Technologie" (TNT) ("English: Wing of New Technology") wing configuration that had been originally developed by Dornier for their earlier Dornier 228 utility aircraft. While much of the wing design is a straightforward, if scaled-up, implementation of TNT, it was furnished with novel "Super Shark" blended winglets, which were developed and incorporated into the wing around 2001/2002. The low-mounted position of the wing was uncommon amongst Dornier-built aircraft; prior aircraft designs, including the Do 28, Dornier 228 and Dornier 328, had all featured wings that were mounted in a high position relative to the fuselage.
