Shenyang Aircraft Corp has manufactured the first engine pylon for the Comac C919 narrowbody.
The pylon will be sent to engine maker CFM International and be mounted on its flying test bed when the Leap-1C engine gets tested, says a Comac spokesman.
He adds that it is important to verify that the pylon fits well with the engine. The successful manufacturing of the pylon will also ensure that flight tests for the Leap-1C can be done in time and that the C919 will be able to make its first flight as scheduled in 2015, says the spokesman.
Nexcelle, a joint venture between General Electric and Aircelle, is responsible for the nacelle, thrust reverser and exhaust system that will envelope the Leap-1C engines.
Comac says that Xian Aircraft has also manufactured the mid fuselage and outer wingbox of the C919.
The Chinese airframer announced in August that the C919's first flight has been pushed back a year to the end of 2015. The programme has entered the "most critical stage of engineering development" as detailed design continues. Aircraft structural data has also been distributed, while parts and components manufacturing is currently "in full swing" across at least five different Chinese cities.
Comac has secured 400 aircraft on its backlog for the C919, mostly from Chinese airlines and leasing companies.
