(Reuters) – Boeing Co said late Thursday that it was in discussions with US safety regulators about a manufacturing issue found last year in its 787 Dreamliner.
Como News Radio in Seattle called for 787 to include vertical tail fin, citing federal records, and 680 airplanes could be affected.
This was the fourth production issue to be revealed in recent days involving the 787.
When asked about the latest issue, the Federal Aviation Administration reiterated on Thursday “it is investigating manufacturing flaws affecting some Boeing 787 jetliners” but had not made a decision whether to issue new airworthiness instructions.
KOMO stated that the issue involved excessive gaps that could pose a safety concern and over time the strain on the aircraft’s structure.
Boeing said in a statement that the new report “the issue was found in late 2019” and addressed in production. It determined its engineers “it does not immediately affect the safety of the flight and does not require immediate action.”
The largest US airplane manufacturer said it is “working with the FAA to finalize guidance for the in-service fleet. We expect that inspection will be required once during regularly scheduled maintenance.” “
Boeing said on Tuesday that it was discovered during construction of the 787 horizontal stabilizer that some components were added with greater force than specified, which could result in improper differential verification and brightness.
One person on the matter reported that the issue of horizontal stabilizer may require inspection of about 900 airplanes.
On Monday, the FAA said it was also investigating two other construction flaws in the 787.
Boeing said in August that the airlines had removed eight 787s from service as a result of two separate manufacturing issues in the torso sections.
Boeing said on Monday that some airplanes had shims that were not of the appropriate size, and some airplanes had areas that did not meet skin-flatness specifications. Shim is used to close small gaps in joints. Boeing identified the shining issue in August 2019.
Boeing stated, “These issues, individually, are not up to specifics, yet meet the limits load conditions. When combined in one place, they are in a condition that meets the limit load requirements Don’t. “
