Ntsb Human Error Statistics

and Crew Resource Management (“CRM”) Procedures Are the Keys to Avoiding Aviation Fatalities The National Transportation Safety Board (“NTSB”) recently released its statistical aircraft accidents due to human error data calculating transportation fatalities across all modes of transportation in 2011. aviation accidents due to human factors There were 494 fatalities in aviation. The breakdown was as follows: general aviation, 444; air taxi, 41; human error in aviation accidents foreign/unregistered, 9; airlines, 0; commuter, 0.[1] In comparing the 2011 data against the prior decade or so, there are certainly positive signs. But, like all raw statistics,
Human Factors Analysis And Classification System (hfacs)
the numbers are most useful when integrated into a longitudinal data comparison from which conclusions are drawn. The NTSB fatality statistics draw a conclusion that might not be obvious from the 2011 data alone: Human error absolutely dominates as the leading cause of aviation fatalities (and injuries). There are two keys to avoiding aviation fatalities: percentage of aviation accidents caused by human error developing and following good SOPs and CRM procedures. This article will examine some of the persistent human causes of aviation accidents, many of which are merely outgrowths of the failure of aviation organizations to develop, adhere to, and not willfully disregard SOPs. The second cause of aviation fatalities examined in this article is the failure of flight deck crews to follow CRM procedures. Complications that lead to failure to follow CRM procedures include factors such as cockpit chaos; multi-lingual cockpits; failure to maintain cockpit discipline; surprise; and failure, during emergencies, to rely on the crew member with the most flight time, if appropriate given the constitution of the crew as a whole. Accidents Can Be Avoided Through Proper Cockpit Procedures and Compliance With SOPs On September 16, 2013, NTSB Member Robert Sumwalt (“Member Sumwalt”) gave a presentation to the Southern California Aviation Association[2] on the importance of SOPs. Member Sumwalt, quoting from an NTSB accident report, noted that, “[w]ell-designed cockpit procedures are an effe
