Russian airframer Aviastar has completed assembly of the first major section for the Irkut MS-21 medium-range twinjet.
The rear fuselage segment has been built for the static-test programme. Irkut says it should be delivered to Riga, Latvia, to undergo pressurisation testing at a local facility.
"To validate the design service life of 60,000 flights, trials will be carried out...and involve 300,000 test cycles lasting five minutes each," it says.
Aviastar intends to build the first MS-21 carbonfibre empennage in 2013 using materials and moulds to be supplied by the Obninsk-based composite specialist Technologia.
Under the co-operation programme, Aviastar is responsible for manufacture of around 1,300 items for MS-21 airframe structures. To date, it has produced test examples of some 900 primary parts.
MS-21 airfame designer Sergei Savin says a portion of these has already been handed over to the Central Aerohydrodynamics Institute for structural testing.
He adds: "Other parts are being checked for lightning and static electricity protection at the Gromov Flight Test Institute."
