Boeing faces additional malpractice claims


Chicago - Additional safety issues about the 737 MAX jets were reported to the FAA anonymously by the current and former Boeing employees.

A new report revealed four people who are supposed to be current and former Boeing employees called the anonymous safety hotline of the U.S. Federal Aviation Agency to report additional safety problems with the Boeing 737 MAX jets. According to CNN, this happened one day after the Ethiopian minister of transportation released the preliminary report of the Ethiopian Airlines flight 302 crash.

All four denunciations were about the anti-stall system of the aircraft, which was believed to cause the two recent crashes.

"How the Boeing MCAS System Really Works"

The Agency confirmed the reports via its safety hotline and said the calls may require further investigative action about the aircraft's anti-stall system known as MCAS (Maneuvering Characteristics Augmentation System).

Last Month, a report published in the Seattle Times revealed that the Boeing safety inspectors did not fully understand the strength of the new anti-stall system while conducting the safety review for the plane before certification.

Although Boeing 737 MAX series jets have two AOA (Angle of Attack) sensors connected to the MCAS system, the system was designed to intervene with data from just one of the sensors. The updated software now requires data from both sensors to prevent the aircraft from a potential stall.

One of the whistleblowers reported that they once had seen damage on the electrical system that was connected to the angle of attack (AOA) sensor. The AOA sensor provides data to the MCAS system so it can determine whether an intervention is needed to prevent the plane from a stall situation.

It is not the first time Boeing was blamed for not securing plane parts against foreign object debris produced during the manufacturing process.

Two weeks ago, New York Times claimed that Boeing reportedly forced its employees to speed up production despite the employee complains about potential safety risks and defective manufacturing at the Boeing North Charleston factory where the Boeing 787 Dreamliners were produced.

After interviewing more than a dozen current and former employees and reviewing hundreds of pages of internal emails, corporate documents, the New York Times reported that the safety often was sacrificed over the speed at Boeing's Charleston factory.

Boeing did not tell Southwest a safety alert was turned off on the 737 MAX jets

Another mind-blowing claim came on April 28. According to the Wall Street Journal, Boeing did not tell Southwest Airlines, its largest 737 MAX customer, that a safety feature related to the MCAS system was turned off.

The safety feature is a warning system that lights up in the cockpit if one of the AOA sensors transmit faulty data about the plane's angle of attack. The feature is known as the "angle-of-attack disagree light" which was also included in previous generations of the Boeing 737.

The Wall Street Journal reported that Southwest did not know about it until after the Lion Air flight 610 crash in Jakarta, Indonesia.

Safety inspectors and supervisors of the Federal Aviation Administration were also unaware of it, according to the experts that spoke to The Wall Street Journal.
