ISEN 472: Wednesday, February 28, 2018 Lecture Discussions & Activities: 3.1 Cockpit Design and the Kegworth Air Disaster G-OBE left Heathrow Airport for Belfast at 1952 hrs with 8 crew and 118 passengens (including 1 infant) on board. As the aircraft was climbing through 18.000 feet the outer panel of one blade in the fan of the No 1 (left) engine detached. This gave rise to a series of compressor stalls in the No 1 engine, which resulted in airframe ingress of smoke and fumes to the flight deck and fluctuations of the No 1 engine parameters. Believing that the No 2 engine had suffered damage, the crew throttled that engine back and subsequently shut it down. The shuddering caused by the surging of the No 1 engine ceased as soon as the No 1 engine was throttled back, which persuaded the crew that they had dealt correctly with the emergency. They then shut down the No 2 engine. The No 1 engine operated apparently normally after the initial period of severe vibration and during the subsequent descent. The crew initiated a diversion to East Midlands Airport and received radar direction from air traffic control to position the aircraft for an instrument approach to land on runway 27. The approach continued normally, although with a high level of vibration from the No 1 engine, until an abrupt reduction of power, followed by a fire warning, occurred on this engine at a point 2.4 miles from the runway. Efforts to restart the No 2 engine were not successful shuddering, The aircraft initially struck a field adjacent to the easterm embankment of the M1 motorway and then suffered a second severe impact on the sloping western embankment of the motorway. 39 passengers died in the accident and a further 8 passengers died later from their injuries. Of the other 79 occupants, 74 suffered serious injury 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. This engine subsequently suffered a major thrust loss due to secondary fan damage after power had been increased during the final approach to land. Extract from the accident report conducted by the Air Accidents Investigation Branch.JExplanation / Answer
On January 8, 1989 as scheduled domestic flight 092 was on the way from London Heathrow airport to Belfast in Northern Ireland. It was the succeeding flight that was undertaken by the British Midland Boeing 737-400 that day and the jumbo jet was about to its landing destination when a combination of mechanical and individual fault confronted the tragedy.
Getting ready to ground at the East Midlands airport the airplane registered as G-OBME crashed down onto an edge of the M1 motorway near Kegworth, Leicestershire killing 47 individuals and critically wounding furthermore 74 people including seven associates of the air travel squad.
On investigating the reason of the disaster the airplane mishap statement acknowledged that the reason of the disaster was that the in service team member closed down the No.2 engine after a fan blade had splintered the No.1 engine.
This engine consequently experienced the foremost plunge loss due to secondary fan break down after the power was escalated during the concluding move towards landing. However for sure it was a mishmash of faults, mechanical, technical and cognitive which eventually reasoned the airplane to be unsuccessful at the time of its concluding grounding stage.
Succeeding study and investigation has significantly accomplished that managerial malfunction generated the indispensable conditions of individual blunders and managerial letdown also made it worse resulting in fatal consequences. Thus Kegworth air crash was the outcome of a series of malfunction initiating from a mechanical fault.
