On Thursday, local time, Boeing and federal officials said Boeing had once again halted deliveries of its 787 jetliner because of questions about a supplier's analysis of parts near the front of the plane.。The halt to deliveries of the 787 is the latest hindrance involving the twin-aisle aircraft, which Boeing calls Dreamliner and is used mostly on international routes.。

Boeing says the issue does not currently pose an immediate safety concern for aircraft already in service。The Federal Aviation Administration is more cautious, saying it is working with Boeing to determine what repairs will be needed on planes recently delivered to airlines.。

The Federal Aviation Administration said in a statement on Thursday that "Boeing has temporarily halted deliveries of the 787 Dreamliner after notifying the FAA that further analysis of airframe components is underway."。"。"Delivery will not resume until the FAA is confident the issue has been resolved."。"

In response, a Boeing spokesman said the company "discovered an analytical error by our supplier related to the 787 forward pressure bulkhead," which separates the aircraft's nose from the pressurized compartment.。Boeing did not name the supplier.。

It is reported that as early as September 2020, Boeing 787 broke out with production quality problems.。One of the problems exposed at the time was that the shims between the two structural parts of the aft section of the aircraft fuselage were not installed in place, resulting in insufficient structural strength in the aft section of the aircraft fuselage.。The other is that the composite fuselage of the aircraft fuselage mounting skin is not polished and smooth, which makes the skin unable to fully fit and reduces the strength of the skin.。At the time, the problem directly led to the grounding of eight 787s for inspection, and it was estimated that about hundreds of 787s had similar problems.。

After the FAA's involvement in the investigation, the 787 quality problems were completely exposed, which eventually led to the U.S. FAA (Federal Aviation Administration) on May 29, 2021, ordering the Boeing 787 to stop delivery.。The ban on deliveries was lifted on July 29, 2022, for 14 months.。

In response to the latest shutdown, Boeing said near-term deliveries will be affected, but is not expected to change the company's forecast for deliveries this year.。
