April's 1.9 percent increase was the biggest percentage advance since December 2007, when orders rose 4.1 percent, the Commerce Department said.

However, March orders were revised sharply lower, falling 2.1 percent from the previously reported 0.8 percent decline.

Analysts polled by Reuters had expected overall new orders to rise 0.4 percent in April, and orders excluding transportation to ease 0.3 percent.

New orders excluding transportation climbed 0.8 percent in April after declining 2.7 percent in March, boosted by orders for communications equipment, machinery and fabricated metal products.

However, there were some dark spots in the report. Civilian aircraft and parts tumbled 6.8 percent after surging 7.5 percent in March.

Non-defense capital goods orders excluding aircraft, a closely watched proxy for business spending, fell 1.5 percent in April. The prior month was revised to show a 1.4 percent decline, previously reported as a 0.4 percent gain.
