The ICA IS-29 was a sailplane built in Romania in the 1970s. The prefix IS comes from Iosif Silimon, the romanian IAR (Industria Aeronautică Română) plane engineer that designed it. The 15-meter single place sister of the IS-28 series, the IS-29D2 single-seater has retractable gear, camber-changing flaps and Hütter type airbrakes on the upper wing surface only. The T-tail has a fixed stabilizer and elevator. The –29D model is of all metal construction while the earlier –29B has wooden wings. Developments include 19 m. (-29E2) and 20 m. (29E3) versions and a flapless, fixed gear 16.5-meter ‘club’ model (-29G). All EXP except IS-29D2, ATC
Like the IS-28, the IS-29 was also produced in a motorglider version, designated the IS-29EM. This shared the low-set wings and three-point undercarriage of the IS-28M2, and the new wings of the IS-28MA.
