The FAA, the US aviation regulatory agency, said that even if there is no direct threat to flight safety, new manufacturing quality issues need to be addressed.
The Federal Aviation Administration (FAA) stated that some undelivered Boeing 787 Dreamliners have new manufacturing quality issues, and the largest aircraft manufacturer in the United States will resolve the issue before the aircraft is delivered.
The FAA said late on Monday that the problem was “near the nose of certain 787 Dreamliners in the company’s undelivered aircraft inventory.” This problem was discovered during a system-wide inspection of the Boeing 787 shimming process required by the FAA. “
The FAA added, “Although this issue does not pose a direct threat to flight safety, Boeing has committed to repair these aircraft before resuming deliveries.” The air regulator added after reviewing the data, “It will decide whether to respond to the Similar modifications were made to the 787 aircraft put into commercial service.”
Boeing declined to comment. Reuters first reported on the new production problems of Boeing’s troubled 787 Dreamliner. The company has approximately 100 undelivered 787s in inventory.
After the FAA expressed concern about its proposed inspection method, Boeing suspended 787 deliveries at the end of May, stating that it was “waiting for more data from Boeing before determining whether the company’s solution complies with safety regulations. .”
In May, the FAA issued two airworthiness directives to address the production problems of aircraft in service.
Since the end of last year, the American aircraft manufacturers 737 MAX and 787 have been plagued by electrical and other problems. After a five-month interruption, the company resumed 787 deliveries only in March, but stopped deliveries again in May.
Two important US lawmakers said in May that they are seeking records from Boeing and the Federal Aviation Administration on production issues involving the 737 MAX and 787 Dreamliner.
The FAA said in September that it was investigating manufacturing defects involving some of the 787 Dreamliner. Boeing said in August that the airline operating its 787 Dreamliner had suspended eight aircraft due to two different manufacturing issues.
In September, Boeing stated that the gasket size of some 787 aircraft was inappropriate, and the area of some jet aircraft did not meet the skin flatness specifications.
At a meeting last month, Boeing CEO Dave Calhoun stated that the 787 aircraft “performed well.”
But he added: “The FAA naturally wants to learn more about the analysis and process control we implement, which is different from what we used to, so that we can become more perfect.”
Calhoun stated that he hopes that the FAA’s review of Boeing’s method will be “monthly, not more than a calendar year.”
In February of this year, Reuters reported that Boeing had begun arduous maintenance and forensic inspections to repair at least 88 parked 787 aircraft deep internal structural integrity defects.
The fuel-efficient 787 has always been favored by airlines. They have ordered nearly 1,900 advanced dual-aisle jets with a list price of nearly US$150 billion.
In recent years, the FAA has been criticizing some of Boeing’s safety practices and imposed a fine of 6.6 million U.S. dollars on Boeing in February for failing to comply with the 2015 safety agreement.
After two fatal crashes, the agency did not allow the Boeing 737 MAX to resume flight for nearly 20 months, and only after adding important safety measures to critical systems.
Last month, Reuters reported that the FAA told Boeing in May that its planned 777X was not yet ready for important certification steps and warned that it would “actually” not be until mid-to-late 2023. The aircraft will be certified.
