Boeing said Feb. 4 that about 50 undelivered 737 MAX aircraft had to be reworked after supplier Spire Aerosystems discovered quality issues with some of the aircraft's fuselages, which could lead to near-term delivery delays.
According to the report, an industry source previously said that an employee of the Spire Aviation System found that the spacing of the drilled holes on the fuselage window frame was unqualified during the inspection, but Boeing said that the safety of the aircraft was not affected, and the existing 737 series aircraft can continue to fly.
This was confirmed by Boeing Civil Airplanes Group CEO Stan Dill in a letter to employees. He also said that while this potential risk will not immediately pose a flight safety issue, about 50 undelivered aircraft will be reworked, focusing on checking the location of two holes in the window frame assembly.
According to statistics, as of February 5, Boeing has found this quality problem on the fuselage of 22 aircraft, about half of the number of inspections made. In addition, some 737 series aircraft in service may also have this problem.
Reuters reported that such quality problems are common in aircraft manufacturing, but at the moment the aircraft type is facing strict scrutiny due to the failure of an inline emergency door in the air of a Boeing 737 MAX 9 passenger plane of Alaska Airlines.
