The Boeing Co. has completed an engine run test on its new 747-8 Freighter, the company said Wednesday.

“We are very pleased with the engines’ performance during this test,” said Mo Yahyavi, vice president and general manager of the 747 program. “The engines and all the systems performed as expected.”

Boeing began the engine run at 10 a.m., yesterday here in Everett. The engine run test began with the auxiliary power system providing power to start the first of four General Electric GEnx-2B engines. The engines are run at varying levels of power during the test to make sure everything performs as expected.

Basic systems checks continued throughout the test. The engines were powered down and inspected and will be restarted following a technical review. The team completed a vibration check and monitored the shutdown logic to ensure it functioned as expected.

“This milestone is an exciting one for the GEnx-2B team and we anticipate the engines will continue the same high performance that we have experienced in our ground and flight tests,” said Tom Brisken, general manager of the GEnx Program at GE Aviation.

Boeing has said its 747-8 Freighter will make its first flight early next year.
