The Impact of Fatigue on Threat and Error Management Performance During Line Operations Safety Audit Observations
By JEANIE HOOD, U.S. AIR FORCE AMC/SEF WITH DR. STEPHEN POWELL, JENNIFER SAGE, AND BRITTNEY HENDERSHOT, SYNENSYS, LLC
Fatigue is defined by the International Civil Aviation
Organizational as a “mental or physical performance
capability resulting from sleep loss or extended
wakefulness, circadian phase, or workload (mental
and/or physical activity) that can impair a crew
member’s alertness and ability to safely operate an
aircraft or perform safety–related duties.” Between
2003–2018, 32 crew fatalities were associated with
fatigue across the Air Force, with four fatalities
attributed to the Mobility Air Force.
Fatigue–related mishaps accounted for over $2.4
billion of medical and material costs. While only 4
percent of all mishaps had fatigue as a factor, these
mishaps accounted for over 18 percent of the total
cost. More than 25 percent of fatigue–related mishaps
were Class A mishaps.
