Boeing 737 MAX Ethics: MCAS Failures and Corporate Responsibility

Introduction: Aviation History and the Ethics of Innovation

For millennia, humanity has been fascinated with air travel. History is riddled with risk-takers who used the innovations of their time to engineer mechanisms for flight. These mechanisms often failed, resulting in both death and disappointment. Yet such setbacks never deterred the human spirit of innovation as it relates to air travel. As far back as 1506, Leonardo da Vinci, in his Codex on the Flight of Birds, detailed many aerodynamic principles of nature and flight that served as precursors to modern aviation. Nearly 200 years later, in 1783, Joseph-Michel and Jacques-Étienne Montgolfier created the first hot air balloon, using a duck, a sheep, and a rooster as its first test subjects. By 1809, the study of aerodynamics had become much more mainstream due to the contributions of philosopher George Cayley and his seminal work On Aerial Navigation. By the early 1900s, the Wright brothers, during the industrial revolution, altered air flight forever with their well-documented flight at Kitty Hawk. This monumental event ushered in an entire industry that has ultimately had unfathomable impacts on human civilization.

With this achievement came the rise and viability of an entire aerospace industry. People became better able to move from place to place in a more efficient and safer manner. Goods could now be transported seamlessly across borders. Even space travel became far more possible due to the innovations first established by the Wright brothers. Unfortunately, as with most innovations in society, those with nefarious motives also took advantage of this progress. Many of the deadliest wars were fought shortly after the invention of the airplane. Just as people and goods could be transferred through air travel, so too could weapons of mass destruction. The world witnessed the attack on Pearl Harbor on December 7, 1941, carried out by Japanese aircraft, and the horrifying destruction of the September 11th terrorist attacks. All of these events — both the beneficial and the catastrophic — stem from how humans choose to leverage innovation to serve or to destroy (Adamson, 2020).

Within each of these decisions, innovations, and technological breakthroughs, there was always an element of ethics. Ethics underlie many of the attributes and principles ascribed to the historical figures described above. For example, Joseph-Michel and Jacques-Étienne sent animals rather than humans to test their hot air balloon — it would have been unethical to use human test subjects in an unproven and unreliable aircraft when there was no meaningful difference in outcome between sending a human and sending another living subject. Likewise, there were profound ethical considerations involved in using aircraft as tools of war. On August 6, 1945, the United States became the first nation to use nuclear weapons in armed conflict, delivering them by aircraft. The two bombs killed over 350,000 people, many of whom were civilians. These acts illustrate how ethics within the aerospace industry play a major role in shaping how air innovations are applied in society.

Although there are many ethical considerations within the aerospace industry, they vary considerably in depth and magnitude. As innovations continue to occur, so too do the ethical considerations surrounding them. Of particular recent note is the Boeing 737 MAX. In developing and deploying this aircraft, the company faced a variety of ethical considerations that ultimately affected the public, its shareholders, employees, and society at large. The implications of these decisions will resonate throughout the industry for many decades to come. Multiple crashes and the resulting loss of human lives eroded public trust in Boeing's ability to design safe and reliable air travel products. This erosion of trust lowered profitability, as air carriers became less willing to purchase Boeing's products, which in turn adversely affected the company's stock price. Shareholders — often ordinary retail investors — also suffered as their holdings declined due to poor ethical decisions by company management. A few wrong choices impacted a very large proportion of the population, both directly and indirectly. The central argument of this paper is that ethical decision-making must be embedded in company culture and reinforced by senior management (Ahmed, 2019).

To understand the ethical implications of the Boeing 737 MAX debacle, it is first necessary to examine the types of ethical conflicts that affect large corporate organizations. The 737 MAX suffered from a range of ethical issues. The first was related to design flaws in the flight-control software. Second, competitive pressure from Boeing's rival Airbus created internal urgency and rushed development timelines. Third, Boeing lacked a robust communication mechanism, resulting in a lack of transparency regarding new software within the 737 MAX model. Finally, the FAA was heavily negligent in its monitoring of the certification process, even after the first crash.

These elements can be distilled into roughly three ethical principles. The first is Duty/Responsibility vs. Malice/Indifference — a scenario in which corporate managers simply ignore unethical conduct by others. This is common on Wall Street, where traders use proprietary information to "front-run" other traders' orders using complex financial algorithms. The second is Duty vs. Self-Interest, which encompasses bribery, misuse of power, and intentional information leaks. Here, managers or executives may subordinate their duty to others in order to advance their own interests. The third concept — arguably the most directly relevant to Boeing — is Duty vs. Duty. In this scenario, corporations must balance the duty to maximize shareholder wealth against the duty to act responsibly toward society. This tension can even extend into the grey area between the duty to maintain confidentiality and the duty to blow the whistle on harmful behavior. Table 1 below summarizes these ethical concepts.

Table 1: Ethical Conflict Concepts and Corporate Examples

Ethical Frameworks Applied to Corporate Decision-Making

Duty/Responsibility vs. Malice/Indifference: Ignoring ethical whistleblowers due to indifference.

Duty vs. Self-Interest (Conflict of Interest / Principal-Agent Problem): Wall Street fund managers charging excessive fees without delivering commensurate investment returns; investment banks front-running client trades for profit.

Duty vs. Duty (Conflicting Ethical Considerations): Duty to shareholders vs. duty to society.

Each of these ethical concepts is directly correlated to Boeing and its handling of the 737 MAX. The first and perhaps best-documented ethical issue concerns pilot training. Boeing designed the 737 MAX as a natural extension of its highly successful 737 model — the best-selling commercial aircraft in aviation history, with nearly 16,000 units sold. Building on that success, the company sought to leverage the infrastructure of the prior model to design an improved version. However, development of the 737 MAX was rushed internally due to competitive pressure from Airbus, which had announced its own upgraded A320 family of aircraft. The Airbus aircraft were larger, more fuel-efficient, and cheaper for operators to maintain. To remain competitive, Boeing released the 737 MAX — which became the fastest-selling airliner in modern aviation history, with 5,000 orders from 100 airlines worldwide. Critically, Boeing designed the MAX to be sufficiently similar to the previous 737 models so that pilots would not require retraining, further enhancing the aircraft's value proposition (Arnold, 2019).

Pilot Training and the Duty vs. Duty Dilemma

This design decision represented the first major ethical consideration. By avoiding retraining requirements, Boeing saved millions in expenses. While the similarity to the prior model offered a reasonable justification, the MAX was a new aircraft with new systems, and an argument can be made that Boeing had a duty to familiarize pilots, crew, and other stakeholders with those differences. This situation is a clear example of the "Duty vs. Duty" conflict described earlier. The company had a duty to shareholders to maximize profits and a simultaneous duty to the aviation industry to properly prepare the personnel who would operate the aircraft daily. Boeing chose the former, electing not to spend large sums on pilot training based on the belief that the aircraft's similarities to its predecessor made such training unnecessary — a belief reinforced by the widespread existing familiarity with the prior model among air carriers. Opponents of this reasoning, however, can point directly to the lack of training as a contributing factor in two devastating and high-profile crashes. Moreover, it is arguable that properly training pilots would have been in shareholders' best interests as well, given the catastrophic reputational and financial damage that followed.

The Boeing 737 MAX groundings that resulted from the crashes illustrate how a short-term cost-saving decision can produce far greater long-term losses — a cautionary lesson for any organization weighing financial efficiency against comprehensive safety practices.

The next ethical issue is related to the MCAS (Maneuvering Characteristics Augmentation System) software, a new feature within the 737 MAX product. This software was needed primarily because of design changes relative to the older 737 model. The MAX featured the GE Leap engine, which was significantly larger than its predecessor and required placement further forward on the wings. This repositioning created a substantially higher risk of the aircraft stalling if the pilot angled the nose too high. The MCAS software was introduced to mitigate this risk: it would automatically nudge the nose of the aircraft downward if onboard sensors detected that the angle of attack was dangerously steep. Boeing touted this system as an additional safety feature, intended for deployment only in extreme circumstances (Bellamy, 2019).

This framing, however, led Boeing directly into its next ethical failure. The MCAS software was never disclosed to pilots. As noted above, Boeing had already decided against retraining pilots on the new model. No training was provided on the MCAS system — not on its purpose, its functioning, or how to respond if it activated unexpectedly. More egregiously, the MCAS system was not even mentioned in the flight manuals. This omission added an unnecessary and dangerous layer of complexity to the aircraft's operation and contributed directly to two fatal crashes.

When MCAS activates, it tilts the rear stabilizer upward, causing the nose of the aircraft to point downward. Under normal circumstances, a pilot can correct this by pulling back on the control column to raise the nose to a neutral position. However, the new MCAS system was designed to reset each time the pilot initiated this correction, potentially triggering again if sensors detected the nose rising too high. This created a dangerous "tug-of-war" between the pilot and the software. During the first 737 MAX crash — involving Lion Air Flight 610 — this cycle repeated nearly 22 times over the course of the flight.
