rainer version (see UTI) of the
I-16 Type 5. Introduced in 1937. At the time each
fourth airframe of the I-16 was completed as a trainer. UTI-4 engined by the M-25,
later M-25A and M-25V power plant.
All improvements of production versions were reflected on trainers, like new instrumentation, improved flaps, new engines.
Some of UTI-4 had fixed landing gear.
Despite the I-16 was withdrawn from service in the
1944, the UTI-4 trainers still were used for pilot's training. Reconnaissance
front line missions also were flown by the two-seaters during early stages of the Great Patriotic War.
No armament carried to save weight.
Rear sliding "Blind flight" hood on the rear cockpit for instrument training.
