Boeing improperly conducted late-night engine testing in Seattle

More than 100 people complained to King County after Boeing loudly tested the engines on its new 777x late Tuesday night.

"It's like a mini earthquake at my house," said Colin, a Beacon Hill resident. "It seems like Boeing didn't have any regard for their neighbors during this time."

King County officials say they gave the company authorization to conduct engine run-up testing from 6-9 p.m. Tuesday on the plane parked at Boeing Field.

County officials say Boeing actually conducted the tests from 9:30 p.m.-12:30 a.m., in violation of the airport’s noise abatement policy.

County officials say they received complaints from Beacon Hill, Georgetown, South Park and southern West Seattle.

Boeing issued this statement to KIRO 7: “The test extended beyond the allotted time agreed to with the King County Airport and we are sorry for disrupting nearby residents. This was not a normal occurrence and we are making adjustments to prevent it from happening in the future.”
