A US Senate subcommittee has summoned Boeing CEO David Calhoun to testify about the company’s jetliners in an inquiry prompted by new safety-related charges from a whistle-blower.
The panel said it is to hold a hearing on Wednesday next week featuring a Boeing quality engineer, Sam Salehpour, who is expected to detail safety concerns involving the manufacture and assembly of the 787 Dreamliner.
The subcommittee said in a letter that those problems could create “potentially catastrophic safety risks.”

Boeing would not say whether Calhoun plans to attend the hearing.
In response to a query from The Associated Press, a spokesperson said only that the company is cooperating with the subcommittee’s inquiry and has “offered to provide documents, testimony and technical briefings.”
The US Federal Aviation Administration has also been investigating Salehpour’s allegations since February, the subcommittee said. It did immediately respond to a request for comment.
Salehpour, whose concerns were featured in a New York Times article on Tuesday, is also expected to describe retaliation he faced after bringing his concerns forward.
According to that account, Salehpour worked on the 787, but grew alarmed over changes to the assembly of the fuselage, the main body of the aircraft. That process entails fitting together and fastening giant sections of the fuselage, each one produced by a different company, Salehpour said.
Salehpour told the Times he believed Boeing was taking shortcuts that led to excessive force in the assembly process, creating deformations in the composite material used in the aircraft’s outer skin.
Such composites often consist of plastic layers reinforced by a mesh of carbon or glass fibers, increasing tensile strength and making them a useful substitute for heavier metals.
However, composites can lose those benefits if they are twisted or otherwise deformed.
Salehpour alleged that such problems could create increased material fatigue, possibly leading to premature failure of the composite, according to the Times’ account. Over thousands of flights, those pieces of fuselage could risk breaking apart mid-flight.
Salehpour said that Boeing not only failed to take his concerns seriously, it silenced him and transferred him to work on a different jetliner, a move he took as retaliation.
In a 1,500-word statement, Boeing said it was “fully confident” in the 787 and called concerns about structural integrity “inaccurate.”
The company added that the issues raised in the Times story “do not present any safety concerns” and said the 787 “will maintain its service life over several decades.”
“Retaliation is strictly prohibited at Boeing,” the company said in the statement, adding that it encourages employees to “speak up when issues arise.”
Tropical Storm Usagi strengthened to a typhoon yesterday morning and remains on track to brush past southeastern Taiwan from tomorrow to Sunday, the Central Weather Administration (CWA) said yesterday. As of 2pm yesterday, the storm was approximately 950km east-southeast of Oluanpi (鵝鑾鼻), Taiwan proper’s southernmost point, the CWA said. It is expected to enter the Bashi Channel and then turn north, moving into waters southeast of Taiwan, it said. The agency said it could issue a sea warning in the early hours of today and a land warning in the afternoon. As of 2pm yesterday, the storm was moving at
DISCONTENT: The CCP finds positive content about the lives of the Chinese living in Taiwan threatening, as such video could upset people in China, an expert said Chinese spouses of Taiwanese who make videos about their lives in Taiwan have been facing online threats from people in China, a source said yesterday. Some young Chinese spouses of Taiwanese make videos about their lives in Taiwan, often speaking favorably about their living conditions in the nation compared with those in China, the source said. However, the videos have caught the attention of Chinese officials, causing the spouses to come under attack by Beijing’s cyberarmy, they said. “People have been messing with the YouTube channels of these Chinese spouses and have been harassing their family members back in China,”
UPDATED FORECAST: The warning covered areas of Pingtung County and Hengchun Peninsula, while a sea warning covering the southern Taiwan Strait was amended The Central Weather Administration (CWA) at 5:30pm yesterday issued a land warning for Typhoon Usagi as the storm approached Taiwan from the south after passing over the Philippines. As of 5pm, Usagi was 420km south-southeast of Oluanpi (鵝鑾鼻), Taiwan proper’s southernmost tip, with an average radius of 150km, the CWA said. The land warning covered areas of Pingtung County and the Hengchun Peninsula (恆春), and came with an amended sea warning, updating a warning issued yesterday morning to cover the southern part of the Taiwan Strait. No local governments had announced any class or office closures as of press time last night. The typhoon
The Central Weather Administration (CWA) yesterday said there are four weather systems in the western Pacific, with one likely to strengthen into a tropical storm and pose a threat to Taiwan. The nascent tropical storm would be named Usagi and would be the fourth storm in the western Pacific at the moment, along with Typhoon Yinxing and tropical storms Toraji and Manyi, the CWA said. It would be the first time that four tropical cyclones exist simultaneously in November, it added. Records from the meteorology agency showed that three tropical cyclones existed concurrently in January in 1968, 1991 and 1992.
