Additional certification campaign was carried out in the Arkhangelsk region and evaluated the aircraft’s performance in real conditions of natural icing.
A OAKa Russian aircraft manufacturer, has completed additional certification testing program for MS-21, SJ-100 and Il-114 aircraft in natural ice conditions in northern Russia. The campaign was carried out in the Arkhangelsk region, with flights over the White Sea coast, the Kola Peninsula and the Naryan-Mar area.
According to Rostec, the tests were conducted based on data from the meteorological service. During the missions, the crews located clouds with potential for ice formation and entered these areas to monitor, with the help of special equipment, the accumulation of ice on the surfaces of the aircraft.
After reaching the required thickness, the planes were taken to altitudes where their behavior in real natural ice conditions could be evaluated. Among the parameters analyzed were stability, maneuverability and the functioning of on-board systems.
According to the Russian state-owned company, the SJ-100 carried out nine flights within the additional certification program in natural ice. The MS-21 completed six flights, while the Il-114 performed eight missions. During the campaign, the aircraft spent between four and seven hours in flight over areas of the Russian far north.
A Rostec reported that the program was fully fulfilled and that the results demonstrated that the MS-21, SJ-100 and Il-114 meet Russian and international aeronautical standards for operation in natural icing conditions.

In addition to freezing environment testing, the SJ-100 also underwent go-around landings and stall approach warning system checks as part of the additional certification program.
With the completion of this stage, the MS-21 and the SJ-100 They have already headed to Zhukovsky, on the outskirts of Moscow, where they will continue the main certification testing campaign. The Il-114 has also completed checks in Arkhangelsk and is preparing to return.
