On August 1st ,2019, #C919 104 prototype test aircraft completed its first flight. The aircraft flew 85 minutes and landed safely back at Pudong airport in Shanghai. This 104 prototype test fight will essentially undertake flight test activities for avionics system, which is simultaneously a significant milestone for SAIFEI EWIS ( Electrical Wiring Integrated System) product.
This is a new major milestone of the C919 program, paving the way to an acceleration of the flight test campaign.
The 4th prototype of C919 Chinese narrow-body twinjet aircraft, embarks the 4th EWIS system designed and produced by SAIFEI.
Close to the structure and to all the systems in the aircraft, the whole EWIS is an assembly of 500 harnesses and more than 7000 connectors and connections, linking together more than 40 000 electrical extremities and totalizing 88 kilometers of cable length.
SAIFEI has already delivered the EWIS system for the 5th prototype, and will finalize in the coming weeks the delivery of the last development aircraft. Development phase manufacturing activities for C919 EWIS will be completed this year, and serial production is expected to start in a very near future.
