variants with their own articles=The ICA IS-28 was a two-seat sailplane produced in Romania in the 1970s. An all-metal aircraft of conventional design with a T-tail, it was originally produced with 15-metre wings, but in 1973, production shifted to the IS-28B with 17-metre wings and numerous aerodynamic refinements. These included a smaller tail with decreased dihedral, decreased dihedral on the wings, and redesigned fuselage contours. This version first flew on 26 April 1973 and was subsequently produced in versions with flaps (IS-28B2) and without (IS-28B1). Around 100 had been built by the early 1980s, with a substantial number sold for export.The IS-28 was also produced as a motorglider, initially as just a powered version of the IS-28B2 (designated the IS-28M1) and then as the more radically redesigned IS-28M2. This version had an entirely new forward fuselage offering side-by-side seating for the two occupants, wings relocated to a low-set position on the fuselage, and tailwheel undercarriage with main units that semi-retracted backwards into the wings. The rear fuselage, empennage, and outer wing panels remained identical with the sailplane version.
The IS-30 was a refined IS-28B2, identical in most respects other than having all-metal control surfaces (where the IS-28's had been fabric-covered) and a redesigned horizontal stabiliser.
