Repentance as Rebuke: Betrayal and Moral Injury in Safety Engineering

Area of Science:

• Safety Engineering
• Aviation Safety
• Engineering Ethics

Background:

• The Boeing 737 MAX accidents, resulting in 346 fatalities, highlight systemic issues in safety engineering.
• The U.S. federal regulator's approval process for the Boeing 737 MAX is examined in the context of these accidents.

Purpose of the Study:

• To explore the roles of betrayal and moral injury in safety engineering failures.
• To analyze the tension between humility and hubris in engineering complex systems.
• To investigate the relationship between moral injury, outrage, and disaster outcomes.

Main Methods:

• Qualitative analysis of the Boeing 737 MAX case.
• Examination of ethical frameworks in engineering.
• Discussion of corporate culture and employee voice mechanisms.

Main Results:

• The study identifies betrayal and moral injury as significant factors in safety engineering failures.
• Ambiguity, uncertain judgments, and equivocal test results in complex systems exacerbate ethical challenges.
• The need for enhanced employee voice protections indicates a failure in core engineering ethics.

Conclusions:

• When engineers need to rely on external protections to speak up, the ethical foundation of engineering has eroded.
• Addressing moral injury and fostering an environment where skepticism and questioning are valued are crucial for preventing future disasters.
• Systemic failures in regulatory oversight and corporate culture contributed to the Boeing 737 MAX tragedies.
