A trade group representing hundreds of airlines pushed again for additional training on Boeing 's 737 Max plane and for a coordinated effort to ensure the safe return of the aircraft after two deadly crashes.
The Max software was developed at a time when Boeing was laying off experienced engineers and pressurizing suppliers to reduce costs.
Several others who testified also criticized Boeing's pilot training for the aircraft, with some saying that Boeing's zeal to minimize pilot-training costs for airlines buying the 737 Max jet contributed to design errors and inadequate training.
According to Mark Rabin, a former Boeing software engineer, most of the programmers were employed by third party software developers like HCL technologies and Cyient. "All that's very understandable if you happen to guage of it from a industry standpoint". While the final code allegedly complied with their strict specifications, the efficiency of such work was below expectations, as subcontractors were pressured to avoid any major changes that could cause delay. "It took many rounds going back and forth because the code was not done correctly". "Slowly over time it appears to be like to be that's eroded the ability for Puget Sound designers to in discovering". Both the Lion Air crash in Indonesia and the Ethiopian Airlines disasters were linked to the improper work of the Maneuvering Characteristics Augmentation System (MCAS), which was created to prevent the plane from stalling, but instead sent the aircraft into nosedives.
Boeing's top-selling aircraft was grounded in March after two fatal crashes and the company has since begun upgrading the model's flight control system, which has been a key focus for crash investigators.
Rebecca Smith, Aviation lawyer at Irwin Mitchell, who is working on the case against Boeing and Rosemount, said: "Joanna's family are understandably devastated and angry".
A Boeing spokesperson told Bloomberg that safety is consistently the principle focal point, including when working with birth air companions. The news articles wrongly claim Cyient's involvement in software development for the flight test equipment.
In a statement, HCL added that it "has a strong and long-standing business relationship with The Boeing Company, and we take pride in the work we do for all our customers".
