Human Factors Incident Reporting — Page 322, Lesson 523

I want to walk you through a case study in Human Factors Incident Reporting — this is the beginning of a real accident analysis that illustrates how human performance factors can combine to create a catastrophic outcome. We're looking at an accident involving British European Airways — BEA. The context is critical: at the time, air travel was expanding rapidly, and airlines couldn't train new pilots fast enough. That meant many aircraft were being crewed by relatively inexperienced pilots in the P2 and P3 positions — that's the co-pilot and the second officer or flight engineer seats. Now, to make matters worse for BEA — the airline's accident investigation body was the BEA — the Bureau d'Enquêtes et d'Analyses, the French authority — but here the text refers to BEA the airline's own difficulties. On the day after the accident, a Monday, there was a scheduled worldwide strike of all pilots affiliated to the Association of Airline Pilots. The UK body is the British Association of Airline Pilots — BALPA. That strike caused a massive increase in the number of people flying on that Sunday, because passengers were trying to avoid the effects of the dispute. In the UK, all BALPA pilots would be on strike. However, not all UK pilots belonged to BALPA. Many belonged to GAPAN — the Guild of Air Pilots and Air Navigators. GAPAN was opposed to taking industrial action. The relationships between BALPA and GAPAN members within BEA at the time were distinctly 'cool' — meaning strained, unfriendly. Now let's look at the people involved, specifically the captain. Captain Stanley Key was in charge of the flight. He was a staunch GAPAN member and was totally opposed to the decision to strike on the following day. He was extremely experienced — both as a pilot on the Trident aircraft type and as a Training Captain. Key could best be described as an 'old fashioned' pilot. He was ex-RAF — Royal Air Force — and was equipped with what the text calls the 'right stuff' — that classic, no-nonsense, highly disciplined pilot mentality. He flew that aircraft 'by the book' and was extremely intolerant of anyone who didn't get everything absolutely correct. He also had a temper. His explosions were famous throughout BEA — these involved violent verbal outbursts, massive increases in blood pressure, and a marked change in facial colour. His outbursts when supervising trainee pilots were well known throughout the company. Here's a critical medical detail that was unknown to anyone at the time of the accident: Captain Key was also suffering from arteriosclerosis. Many of the arteries in his heart had actually narrowed to a — and the excerpt cuts off there, but you can see the significance: a captain with a known explosive temper, under professional stress from the strike dispute, and with undiagnosed coronary artery disease. So what we have here is the human factors foundation of this accident: an experienced but intolerant captain, a crew with relatively inexperienced P2 and P3 pilots, a toxic professional relationship between union factions within the same airline, and a hidden medical condition. These are the kinds of factors that incident reporting systems are designed to capture — because when you put them together, you get a recipe for disaster.
