In the aviation industry, the safety of the people who fly is directly linked to the decisions that are made by the employees of the organizations that produce the airplanes and engines that power them. As a member of such an organization, Mr. Herzner experienced the gravity of making such decisions when he was involved with an airplane accident where 111 people lost their lives. That experience caused him to reflect on how and why such decisions get made. He drew some important conclusions and used them to formulate recommendations on how to make decisions which avoid such devastating consequences.
However when several recent very big events involving large organizations came into the news, he used them to benchmark his recommendations. What he found was several of those event involved unethical behavior. That was an eye-opener because he had never been involved with such behavior. That led him to modify his perspective on how decisions get made.
Using all of that, Mr. Herzner describes the principles that influence how decisions get made and makes recommendations on how organizations and the people in them can avoid what he calls the ‘doomsday event”.
During my 38 year career at GE Aircraft Engines, I was privileged to have had the opportunity to work on a variety of projects ranging from advanced technology demonstrator engines, military bomber and fighter engines and commercial engines for many of the world's commercial airplanes. It doesn't get better than that for a person who has been fascinated with airplanes and aviation for his entire life. In addition to that, I worked for a good company which considered safety and reliability as being their underlying value. Then on July 19, 1989, a DC10-10 powered by CF6-6 engines crashed in Sioux City Iowa killing 111 passengers. At the time of the accident, I was the engineering manager responsible for the CF6 engine product line.

The post-accident investigation revealed that the event 48 was initiated by the failure of the fan disc which was at the front of the engine mounted in the tail of the three engine DC10-10. That failure released high energy debris which breached all three hydraulic lines running through the horizontal stabilizer of the airplane. That loss of hydraulic pressure made the aircraft essentially uncontrollable and, in spite of heroic efforts by the crew, the airplane crash landed in Sioux City.
That accident was a life changing event for many people especially the victims and their families. However, what I didn't expect was that it was life changing for me as well. Why? Because a number of years before the accident, I was working on a problem which was eventually proven to have been the initiator of the event. Not only that, in retrospect, I concluded that I had made a decision which, had it been different, may have prevented the accident. I was devastated!
For a number of years following the accident, I tried to figure out why it happened and why a good company and people with good intentions could have made mistakes which led up to this tragedy. I was particularly focused on what I knew and what I did preceding the event. I drew a number of conclusions and, when I became Chief Engineer, instituted a company policy based on those conclusions addressing how we made product safety decisions. That policy is essentially the same as the one GE Aviation uses today.
Following my retirement in 2002, I watched as a number of really big/bad events happened which involved large organizations. Specifically those events were the BP oil spill into the Gulf of Mexico and the GM ignition switch problem. They not only involved a loss of life but had huge financial and reputation consequences for BP and GM. I immediately looked into them and had the thought that, if those organizations had the benefit of what I had concluded about the Sioux City DC10 event, those events might have been prevented.
Then two other huge events involving large organizations happened. They were the Flint Michigan lead in the water and the VW Diesel emissions cheating events. But these events were very different for Sioux City, BP, or GM. Why? Because the involved unethical behavior inside the organization. That was an eye-opener for me. I could not believe that the organizations and the people in them could resort to behavior that was so egregious. That was especially true of the Flint Michigan event where the people and children of the City of Flint were supplied with lead tainted water.
All of this led me up to developing a set of “factors” which I believe influence the way people in large organizations make decisions. They are:
Perception of Risk
Based on these “influence factors” I developed a set of principles which I believe give guidance to those in organizations which are involved in projects which might result in disastrous consequences for the users and the creators of the products involved. These principles are:
Clearly communicate the values of the enterprise
Build and nurture the “right” culture
Always get diverse input when making critical decisions
Trust but Verify
The “logo” is responsible so the “logo” should make the decision
Define individual roles and responsibilities
Well, how does all this relate to aviation, gas turbines, and the “three worlds”? First of all, I believe that the aviation environment (and especially commercial aviation) is different in that the lives of the passengers and crew are immediately and directly linked to the proper functioning of both the aircraft and the engines powering them. The expectation of the “outside world” (the passengers, the future traveler, the governments, the media, the regulators, etc.) is absolute. A safe flight is assumed! The corporation (the second “world” - I use the term “logo”) will be held responsible for their actions both technically and ethically! But, the organization is made up of people! You as members of the organization dictate what the organization does. This then brings up the “third world”. You are members of, not only the “corporate world”, but of the “personal world”. I can tell you from personal experience that, should you be involved in a catastrophic event and if you are a responsible and moral individual, you will judge yourself on what you knew and what you did prior to its happening.
Let me leave you with these thoughts. The aviation business is the “Yankee Stadium” of businesses. It is the most responsible, most technically advanced, and involves huge amounts of money. It is only a place where the best, the brightest, and the most responsible people ought to be. It is also a place where there are risks and risks have to be managed. That means decisions have to be made. Making those decisions is never easy. If you are lucky enough to be involved in this business, always do the best job that you can. That is what is expected of all of us. And, should the “doomsday event” occur, that is what you will have expected of yourself.
