Jet manufacturer Boeing is investigating another quality issue with its undelivered 787 Dreamliner aircraft.

The company announced hundreds of fasteners were incorrectly installed on the fuselages.

Per Reuters:

The latest in a series of manufacturing snags affecting the U.S. planemaker involves incorrect “torquing” or tightening in a Boeing plant of more than 900 fasteners per plane – split equally between both sides of the jet’s mid-body, they said.

There is no immediate concern about flight safety but Boeing is working to understand what caused the problem and will decide how much if any rework needs to be done once its investigation is complete, the sources said, asking not to be identified.

Boeing confirmed the checks in response to a Reuters query on Thursday and said it saw limited to no impact on deliveries.

“Our 787 team is checking fasteners in the side-of-body area of some undelivered 787 Dreamliner airplanes to ensure they meet our engineering specifications. The in-service fleet can continue to safely operate,” a spokesperson said.

“We are taking the time necessary to ensure all airplanes meet our delivery standards prior to delivery. We are working closely with our customers and the FAA (Federal Aviation Administration) and keeping them updated.”


From The Economic Times:

FAA Administrator Mike Whitaker told reporters in Washington he could not comment on the fastener issue, but said he was headed to Boeing’s 787 plant in South Carolina on Friday and would hear from people in the facility.

Shares of Boeing initially fell 1.7% before paring losses to be flat.

The U.S. planemaker has been under scrutiny from regulators and customers since a January 5 incident in which a smaller 737 MAX operated by Alaska Airlines was forced to make an emergency landing after a fuselage panel blew out mid-flight.

The latest manufacturing flaw was discovered inside the company’s South Carolina plant where the 787’s lightweight carbon-composite skin is attached to skeletal supports inside the fuselage sections called longerons.

The sources said the affected fasteners had been torqued from the wrong side, using the head instead of the associated nut.

In January, Boeing issued a bulletin to suppliers that laid out practices to ensure bolts are properly torqued following inspections of 737 MAX 9s grounded in the wake of the blowout.
