Sukhoi Civil Aircraft hopes to make the first engine runs on its PowerJet SaM146-equipped Superjet 100 this week as it awaits authorization to begin flight tests that it now says could take place in about a month’s time. A second aircraft, now undergoing completion, could fly before June, according to Sukhoi.

Initial engine runs on the first aircraft will be followed by taxi and shimmy tests. Approval to fly hinges on the outcome of almost 50 hours of trials at Zhukovsky, Russia, running since early December with an Ilyushin Il-76LL testbed.
