SAO PAULO, Oct 27 (Reuters) - A weaker 2018 performance outlook for Embraer SA EMBR3.SA is not related to a newly announced partnership between Airbus SA AIR.PA and Bombardier Inc BBDb.TO , which should have a limited effect on the Brazilian planemaker next year, Chief Financial Officer Jose Filippo told journalists on Friday.
Filippo said Embraer's preliminary 2018 forecast for weaker revenue and profitability was due to the inefficiency of parallel assembly lines as the company transitions to next-generation aircraft.
