The Sukhoi Superjet 100 has completed runway water ingestion trials at the company's test centre in Zhukovsky near Moscow.
The tests using Superjet MSN 95003 confirmed that the aircraft's two PowerJet SaM146 engines and auxiliary power unit continued to operate normally while travelling along the wet runway at a full range of speeds preceding take-off.
For the tests, a 70m (230ft) -long pool was constructed on the runway and filled to a depth of 40mm (10in).
The aircraft completed 27 runs at speeds ranging between 10kt (19km/h) and 150kt at different engine settings including low speed, take-off and maximum reverse thrust. The tests were monitored by the Russian certification authorities.
