The aircraft was on a scheduled flight from London Heathrow Airport to Belfast International Airport when a fan blade broke in the left engine, disrupting the air conditioning and filling the cabin with smoke. doi: 10.1371/journal.pone.0096131. Results: The aircraft broke into three sections. The ground proximity warning system activated, sounding several "glideslope" warnings. When this fact was subsequently discovered around a hundred 737-400s were grounded and the engines subsequently modified. Specifically, Captain Hunt had not received training on the new model 737-400 since no simulators for this variant existed in the UK at that time. Sixty-eight of the 79 survivors (86%) were assessed at a clinical interview within one year of the disaster. The majority also completed the General Health Questionnaire, the Impact of Events Scale (IES) and the Zung Anxiety and Depression Scales. PLoS One.

Mizushima, Jin It is still regarded as a miracle that no-one on the motorway was hurt. The people of Kegworth are accustomed to the rumble of landing aircraft. But the thunderous rattle that shook their homes that quiet Sunday evening, as many of them settled down to watch television, was something else entirely. Kegworth Air Disaster Human factors contribute to more than seventy percent of airplane accidents compared to other factors. that the pilots acted hastily and contrary to their training. Just before crossing the M1 motorway at 20:24:43, the tail and main landing gear struck the ground and the aircraft bounced back into the air and over the motorway, knocking down trees and a lamp post before crashing on the far embankment around 475 m (519 yd) short of the active runway's paved surface and about 630 m (689 yd) from its threshold. The relationship Flight 092 was also featured in an episode of Seconds From Disaster, called "Motorway Plane Crash".

The presentation reviewed how relatively crude computer-based modelling of WebThe study sought to quantify psychiatric morbidity among survivors of a major air crash and to identify aetiological factors linked with post-traumatic stress disorder (PTSD). Analysis of the engine from the crash determined that the fan blades (LP stage 1 compressor) of the uprated CFM International CFM56 engine used on the 737-400 were subject to abnormal amounts of vibration when operating at high power settings above 10,000 feet (3,000m). This engine subsequently suffered a major thrust loss due to secondary fan damage after power had been increasing during the final approach to land (AAIB 1980, 35).

The pilots believed this indicated a fault in the right engine, since earlier models of the 737 ventilated the cabin from the right, and they were unaware that the 737-400 used a different system. The captain later claimed that his perception of smoke as coming forward from the passenger cabin led them to assume the fault was in the right engine. This would prove disastrous.

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. The pilots attempted to restart the right engine by windmilling, but the aircraft was by now flying at 185km/h (100kn; 115mph), too slow for a restart. He later claimed that the engine instrumentation did not give him any clear indication of the source of the malfunction. points out mitigating circumstances for their actions, highlighting the In summarising the cause of the accident, The Aircraft Accident Report stated The cause of the accident was that the operating crew shut down the No.2 engine after a fan blade had fractured in the No.1 engine. One survivor, Gareth Jones, described the moment when the plane hit the ground as follows: There was a shudder, crash, like a massive motor car accident, crunch, blackness, and I was by the emergency hatch.

A review on the plane revealed that the passengers who had assumed a brace position sustained severe injuries, which was unlikely. 1999. it was properly connected. 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. The argument that people tend to over simplify complex situations particularly during crisis has been is both well documented and significant in the causation of the Kegworth air crash (Besnard. The importance of preparing passengers for an emergency situation was brought to the fore. Lewin, Terry J.

Passengers were aware of smoke and of smells similar to oil or rubber in the cabin. The cabin crew described hearing a low thudding noise and feeling vibrations in the forward galley. Coming not long after the 1985 Manchester tragedy, the Kegworth accident was another blow to an aviation industry that was still reeling from the Tenerife disaster - an accident involving the worst loss of life in a single event - less than ten years before. Similarly, the best performance was a mistake; that is, the pilot thought the bleed air was from the right engine, which was only applicable to the other Boeing models. No eLetters have been published for this article. This may or may not be a fair assessment since few pilots and First Officers fortunately ever experience the actual effects of smoke and fire while in command. For example, captain Kevin Hunt stated that the passengers and the crew did not inform him of the era; the passengers could have reported their seats. This site needs JavaScript to work properly.

The chronology of these events is therefore particularly important in helping to analyse the failure chain that led up to the crash. 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.
