The Kegworth air crash was therefore the result of a sequence of failures originating from a mechanical defect. WebThe majority also completed the General Health Questionnaire, the Impact of Events Scale (IES) and the Zung Anxiety and Depression Scales. Method: As it turned out, this was a coincidence; when the autothrottle was disengaged prior to shutting down the right engine, the fuel flow to both engines was reduced, and the excess fuel, which had been igniting in the left engine exhaust, disappeared; therefore, the ongoing damage was reduced, the smell of smoke ceased, and the vibration reduced, although it would still have been visible on cockpit instruments. 9, pp. The Kegworth The pilots mistakenly shut down the functioning engine. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 11 0 R 12 0 R 20 0 R] /MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> [citation needed], The dials on the two vibration gauges (one for each engine) were smaller than on the previous versions of the 737 in which the pilots had the majority of their experience and the LED needle went around the outside of the dial as opposed to the inside.

The ground proximity warning system activated, sounding several "glideslope" warnings. A key component of any SMS is the reporting system that is populated by crews and others and which provide us with the data from which we can monitor and trend safety performance and, most importantly, uncover possible latent issues that may not be immediately apparent.

The aviation world has dubbed those While Tenerife proved a turning point for the industry as we began to realise the impact that the 'cockpit gradient' has on crew interactions and behaviours, both Manchester and Kegworth shone a light on aspects related to survivability and the psychology the thought processes of passengers and crew involved in an event. The presentation reviewed how relatively crude computer-based modelling of The investigation into the disaster found human error to be a principal cause of the crash.

In order to extrapolate the events of that day it is necessary to examine a chain of events rather than to study each constituent error or malfunction in turn. [online] available from http://www.iafpa.org.uk/news-template.php?t=4&id=1312 [accessed 1 March 2007]. Many accident reports cite human failure as a primary cause (Johnson, 1998). Multiple human factors contributed to the Kegworth disaster, and some of them would have been handled before the flight. Kleemann, Werner Johann It was the second flight undertaken by the British Midland Boeing 737-400 that day and the aircraft was close to its landing destination when a combination of mechanical and human error led to disaster. Accessibility 173-185. 60, pp. The relationship The aircraft was powered by two CFM International CFM56 turbofan engines. Apart from the coincidence of the smoke vanishing when the auto-throttle was disengaged, the pilots may have also been in the habit of disregarding the readings of vibration warning meters, since early ones were perceived to be unreliable. One such aircraft crash that prompted changes to the brace position took place in 1989.
