Zhitong Finance and Economics APP learned that on Tuesday Eastern Time, a current employee of American Airlines giant Boeing (BA.US) became a new "whistleblower", and the timing of this "whistleblower" is quite critical, because just a few hours later, Boeing CEO David Calhoun will testify before the Senate in Washington about Boeing's "broken safety culture".

According to the latest media reports, a Boeing quality assurance investigator at the 737 factory in Renton, Washington, said there were obvious quality hazards in Boeing components. The company mishandled key parts of planes with defects or unresolved issues, and some of those key parts may have been installed on new Boeing 737 MAX planes.

According to a complaint, as of last year, Boeing had "lost" up to 400 parts with failure properties of the Boeing 737 MAX aircraft and deleted records of many of those parts from the company's internal catalog system.

The employee, named Sam Mohawk, also claimed that the company had "intentionally hidden" improperly stored defective parts, including important large parts such as rudder and flaps, before the Federal Aviation Administration (FAA) conducted on-site inspections of Boeing's company. The Senate committee released the memo to its members on Tuesday, Eastern Time; Boeing said it was reviewing the claims and new allegations after receiving the relevant documents on Monday night.

The FAA has previously said that safety issues reported by Boeing employees increased significantly since the cabin door of an Alaska Airlines Boeing 737 MAX 9 aircraft ruptured shortly after takeoff on January 5. After the shocking mid-air panel explosion of the Boeing plane in January, production of the Boeing 737 MAX jetliner quickly plummeted. Boeing's report said that jetliner deliveries fell 55% year-on-year in March, primarily due to safety issues with the production of the 737 MAX. The aviation regulatory agency in the United States has placed strict limits on the production of the 737 MAX and established extremely stringent quality inspection standards following the massive crisis that erupted after the Alaska Airlines explosion event on January 5th.
