Human Factors in Maintenance Essay
Nation pushover DC-8 Flight 2120 took the lives of 247 passengers and 14 crew members 261 in all during takeoff on July 11, 1991. The atomic number 19 was owned by Canadian air lane Nolisair, and was being operated by a Nigerian comp whatever to transport Nigerian pilgrims in and appear of Mecca. The DC- 8 caught fire during take-off from Abdulaziz outside(a) Airport, Jeddah, Saudi Arabia. Pilots noniced problems during earlier stages of take-off and further made it 671 meters in elevation before attempting to turn around for a necessity get. It was too belatedly the under idealistic grinds had overheated began to catch fire.The fire grew and blew out the hydraulics which made the emergency landing impossible. This was the worst wreck a DC-8 had always experienced and has held the record for m whatsoever another(prenominal) old age geting. The NTSB concluded that the fire could concord been handled by leaving the landing gear broad and away from the plane. Although the pilots failed to make the right conclusiveness, and added in force(p) whiz more(prenominal)(prenominal) gentle wrongdoing to the equation, it was the obvious neglect by the precaution police squad that ca gived this horrific accident. at that place are many human beings factors which play a vital component in the resolve. The care team failed to inflate the 2 and 4 main gear wear upons after recognizing the tweet during the pre- escape cock. An attempt to inflate the tires failed because there was no nitrogen available at the location. advance investigation shows later that the charge team recognized and had written up the tires during a previous A inspection plainly was soft touched off and overlooked more than twice before the incident.Human Factors trothThere are many human factors that caused the Flight 2120 force, and most of them are living related. There was a Liveware-Liveware problem with the lose of communicating between the t whiz pop opera tive and Director of Production. The Director of Production never questioned the maven mechanic and was said to wear little contact with the him prior to this happening. Liveware-Hardware issues create because of lose of pendent personnel department amongst the charge team. The forethought team did non start out a qualified person to sign off the jet, leaving the task to the trajectory engine driver who was not in cable with the concern team.The obligation should become land in the principal mechanics transfer to sign off the sustentation hold open ups and the Director of Production should have been more involved by communicating with the lead mechanic and being more involved. There was a break down in forethought pull down in the early stages of this TDY. The tires had been al hit recognized and written up during prior inspections, but haul from the roam Manager to make the mission influenced the care team to overlook lowly maintenance issues at that time. Although check outmingly minor at the time, the issues would later be the ultimate precipitation and failure of the mission.Lack of communication and pressure caused the maintenance team to not see the immensity of inflating the tires to the standard before release on a long mission. The minor task of inflating the tires to the standards before going on the long sortie would have negated the tires heat up and causing the plane to catch on fire and crash. The maintenance team was not the only factor which added to the human factors. The air crew is also responsible for more or less bad stopping point fashioning skills also. During take-off one crew member was recorded stating that he thought he heard a main landing gear tire blow.The pilot failed to act upon and acknowledge this and carried on with the task. Pilots failed to recognize warning lights designed to allege the pilot of landing gear issues. plot of ground taking off the crew failed to use neat radio procedures r egulations that kept them in contact with the tower. The night before the crash the pilots were out shopping and eating and not returning home until hours before take-off.The omit of crew rest could have played a role in decision making abilities amongst the crew. The crew showed up to the aircraft late which pushed maintenance to hurry and ended the pre- safety valve, magnanimous them no time to perform a good complete inspection. Lack of leadership in the cockpit added to the advancement in takeoff. If the co-pilot trusted his own judgment and recognize there was a problem in the main gear he could have stopped the aircraft from taking off.Safety NetsThe crash of flight 2120 could have easily been avoided by simply checking standard procedures sink by international and local organizations. The maintenance holds the bulk of the responsibility in damage of human factors. The communication between the lead mechanic and AME could have been solved by quest the chain of command. The director of ware had very poor communication with the lead mechanic. This caused for a deprivation in communication from the there up the chain. The communication was bemused at this given point in the chain of command and gave little development which is vital in aviation.The AME had direct responsibility to sign off the final for flight and it was handed over to the flight engineer whom had little knowledge of the maintenance operations. The maintenance team failed to complete given checklists and follow standards set by the FFA and international organizations. With the lack of communication, personnel, and leadership, along with added pressure, the aircraft was not mission ready and should have been better managed from top to bottom.The maintenance crew has very stringent tire pressure requirements and the responsibility lies in even the lowest level of operations to complete the task. The warning lights indicated to the cockpit flight crew that problems have arouse and they chose to ignore them. By receiving proper crew rest the night before, they study power have had better decision making skills and could have made the right decision at the given moment. They also became complacent and did not use the communication procedures with the tower. demonstrationHuman factors is the cause of most aircraft accidents and this one is a major example of how many human factors plenty play such(prenominal) a vital role. Flight 2120 shows the importance and how human factors can directly impact everything involved. The importance of being alert and aware(p) of your environs can come down to one decision which can be the determining factor in any situation. The maintenance and air crew failed to follow written guidelines and standards of operation to protect the lives of those on board. The mission was doomed from the start by the maintenance communication breakdown.The lack of qualified personnel should have been one of the counterbalance red flags. Th e decision to not rectify the problem and over look it several(prenominal) times put them in an environment where the tools needed for the job was not present. The lack of leadership from the bottom level of the maintenance crew to the pilot was a major issue. The lowest level maintenance personnel could have stepped up and brought about the problem. The flight of Nigerian Airway 2120 was that caused by human error. The horrific event shows the importance of following set standards and regulations. The crash exposes the vital role in the chain of command and how human error and lack of communication can break down at any level.ReferencesAviationsafetynetwork.comAmerican-bankruptcy.us.gov
