Gulfstream will not be able to deliver its first G500 ahead of schedule by the end of 2017, as promised, because of a delayed supplier.  

The super-large cabin business jet will be ready to service clients as of early 2018 as outlined in the initial schedule given by the company in 2014.  

Jason Aiken, parent company General Dynamics’ chief financial officer, refused to name the supplier or which component is causing the delay but confirmed that it was due to the paperwork necessary to comply with European Aviation Safety Agency (EASA) certification requirements. The G500 is the first Gulfstream aircraft that is seeking joint certification by the US Federal Aviation Administration and EASA at entry into service. 

The new G500 is going to replace the G550, the deliveries of which are phasing out. Gulfstream also announced last delivery of G450 was this January and confirmed that the other new jet – the long-range G600 is expected to enter service one year earlier.
