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) aeronautical engineer who designed it. The 15-metre (49 feet) 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 metre (62 ft) -29E2 and 20 m (66 ft) -29E3 versions and a flapless, fixed gear 16.5-metre (54 feet) ‘club’ model -29G.
The aircraft demands advanced training skills from the pilot, being known for its capability to enter into a deep stall, a maneuvre which can be (and has proven) fatal for unexperienced pilots. The recovery from the deep stall is carried by releasing (pushing) the stick forward until the aircraft speed increases and the sink rate decelerates. The pilot should be always aware of the stalling speed during flight and especially at the proximity with the ground (at take offs and landings) where the recovery from this scenario is impossible to perform.
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.
