The Il-114-300 has begun high-temperature certification testing in Bukhara, Uzbekistan, after arriving there from Zhukovsky near Moscow for a dedicated hot-weather campaign. The Russian turboprop made the nonstop ferry flight to the Uzbek city to support testing aimed at confirming airworthiness in extreme heat and widening the aircraft’s approved operating envelope.
The campaign comes after the type received its certificate in June 2026, but further trials are still needed before its operating limits are fully expanded. Current certification restrictions are reported at between minus 9 degrees Celsius and plus 25 degrees Celsius, leaving hot-weather performance as a remaining hurdle.
Bukhara was selected because of its dry summer climate, with temperatures around 40 to 41 degrees Celsius during the trial period. More than 30 test flights are planned from the airport, covering the powerplant, avionics, auxiliary systems and cabin interior.
The Il-114-300 is powered by Russian-made TV7-117ST-01 engines and remains part of Russia’s effort to complete certification and move the programme toward serial deliveries. Results from the Uzbek campaign are expected to be submitted to Rosaviatsiya to update the type certificate and extend the aircraft’s approved conditions of operation.
