SAO PAULO, April 15 (Reuters) - Brazil's Embraer SA , the world's biggest maker of regional jets, delivered 14 commercial planes and 20 executive aircraft in the first quarter, according to a Tuesday filing.
A year earlier, Embraer delivered 17 commercial jets and 12 executive jets in the first three months of 2013. The company does not consolidate information on deliveries of military aircraft.
Embraer's backlog of firm orders, a measure of expected revenue, rose to $19.2 billion at the end of March from $18.2 billion at the end of December. (Reporting by Brad Haynes Editing by W Simon)
