Embraer delivered 61 executive jets during the fourth quarter, bringing the delivery total for Phenom, Legacy and Lineage aircraft last year to 144. While the fourth-quarter tally exactly matched that of 2009, the Brazilian aircraft manufacturer shipped 29 more airplanes in total last year�a 25-percent increase. By model, Embraer last year delivered 100 Phenom 100s (93 in 2009), 26 Phenom 300s (one in 2009), 10 Legacy 600/650s (18 Legacy 600s in 2009) and eight Lineage 1000s (three in 2009). Embraer claims that the Phenom 100 was the ≥most delivered≤ executive jet in 2010, though this canπt be verified until the GAMA full-year shipment statistics are published next month. The first Legacy 650 was handed over to launch customer Amsair Aircraft in November. Embraerπs firm order backlog�which includes executive, commercial and military aircraft�stood at $15.6 billion at the end of last year. This backlog was boosted in the last quarter, when the aircraft manufacturer inked a firm order in October with NetJets for 50 Phenom 300s, as well as options for another 75.
