Ethical Considerations and Communication Failure. Research articles such as The Ethical Failures Behind the Boeing Disasterssee: https://blog.apaonline.org/2019/04/08/the-ethical-failures-behind-the-boeing-disasters/  Address questions such as:

Did anyone at Boeing behave unethically in approving the plane for sale. Or did communication breakdown lead to the failures (it is now delayed through 2020 by the FAA).  In addition to ethical violations, does their conduct also raise violations of the law? What is the difference between a legal and an ethical violation? Should the penalties be the same for both? Why is the cover up of wrongful conduct often worse than the conduct itself? What are the benefits of full disclosure of unethical behavior? What could Boeing have done to better educate their employees about ethical and legal violations?
