The PD-14 engine designed to power Russia’s MC-21 airliner has cleared emission tests conducted by the International Civil Aviation Organization (ICAO).
The corresponding addition to the PD-14 type certificate was received by UEC-Aviadvigatel, United Engine Corporation (UEC) said in a statement.
PD-14 was first certified by the Federal Air Transport Agency in 2018 and at that time complied with ICAO standards. In January 2020, a new international standard came into force, in which the smoke and emission standards of non-volatile particles were changed – this required additional certification, UEC said.
The MC-21 jetliner fitted with PD-14 turbofan engine has been re-designated as MC-21-310 while the earlier designation was MC-21-300 which flew with the Pratt & Whitney (P&W) engine. The engine has a takeoff thrust from 9 to 18 tons.
PD-14 engine was developed after the earlier PW1400G Engine was denied to it under U.S. sanctions imposed in 2017 against Russian Aerospace entities.
The MC-21 aircraft made its first flight with this domestically-made engine in December 2020.
Serial deliveries of the aircraft fitted with UEC engine is expected to take place at the end of 2021.
