American Airlines Flight 1420 Accident Using The SHELL Model

Abstract



As a collaborative case study, we analyzed the American Airlines Flight 1420 accident using the SHELL Model. The SHEL Model was developed by a Professor Elwyn Edwards in 1972 and it was later modified to the SHELL Model by a human factors consultant named Frank Hawkins. We can see all the human factors that were involved in the accident utilizing following aspects software, hardware, environment, liveware and liveware. The National Transportation Safety Board (NTSB) conducted a thorough investigation and determine that the American Airlines Flight 1420 was a runway overrun accident caused by human factors.

The SHELL Model has proven to be an useful tool when it comes to using the human factors and aviation safety. On this case study, we will use the details from the NTSB report from the American Airlines Flight 1420 NTSB to study all the factors of the SHELL Model that were contributed to the accident.



Liveware–Software

Multiple factors were contributing to American Airlines fatal accident in 1999. To identify the factors and different issues with American Airlines Flight 1420 the SHELL model will be used. One of the major cause of this accident was a breakdown in Liveware–Software. Liveware–Software investigates procedures, manuals, checklists and standard operational procedures (ICAO SHELL Model, 2016).

NTSB ruled that the main causes of the accident were the decision to land in a thunderstorm and that the crew did not arm the spoilers (NTSB, 2001).
