As the accident occurred in Spanish territory, Spain was responsible for investigating the accident. The crash involved aircraft from the United States and the Netherlands, which both conducted investigations as well. The investigations revealed that the primary cause of the accident was the captain of the KLM flight taking off without clearance from air traffic control (ATC). The investigation specified that the captain did not intentionally take off without clearance; rather he fully believed he had clearance to take off due to misunderstandings between his flight crew and ATC. Dutch investigators placed a greater emphasis on this than their American and Spanish counterparts, but ultimately KLM admitted their crew was responsible for the accident, and the airline financially compensated the victims’ relatives.
The accident had a lasting influence on the industry, particularly in the area of communication. An increased emphasis was placed on using standardized phraseology in ATC communication by controllers and pilots alike, thereby reducing the chance for misunderstandings. As part of these changes, the word “takeoff” was removed from general usage, and is only spoken by ATC when clearing an aircraft to take off or when cancelling that same clearance. Less experienced flight crew members were encouraged to challenge their captains when they believed something was not correct, and captains were instructed to listen to their crew and evaluate all decisions in light of crew concerns. This concept was later expanded into what is known today as crew resource management (CRM), in which training is now mandatory for all airline pilots This video is presented as fair use for educational purposes.
