Boeing and Embraer say they now expect their proposed joint-venture to be finalised in early 2020, rather than the previous target of the end of 2019.
Embraer's Praetor 500 business jet has been certified by the European Union Aviation Safety Agency and the United States Federal Aviation Administration.
Brazil's Azul Airlines officially received the first Embraer E195-E2 regional jet at the manufacturer's São José dos Campos facility on September 12.
Embraer chief executive Francisco Gomes Neto says the airframer is well positioned for a promising future after the company posted a narrowing a first half loss in calendar 2019.
