After studying the Aloha aircraft accident in 1933, our group is interested in the investigation in Human performances factors in maintenance and inspection. We have divided the investigation into 5 aspects: Investigation: 1. The lack of inattention of the mechanics in practical procedures and policies planning. Aloha Airline operated inter-island flight in Hawaii, therefore, Aloha 243 was operating in salt water environment. During each flight, there was a risk that the air saturated with salt and water vapour would enter the crevice when the aluminium sheets are failed to be bonded to the fuselage by epoxy adhesive, also corrosion of metal is stimulated. After the accident, a full-scale investigation was launched by the…show more content…
It is unlikely that many mechanics would be willing to sacrifice so much of their personal life in the interest of increased safety throughout the week. - Emotional factors Even if the pitfalls of the night shift are successfully averted, human factors related to the midnight shift must be dealt with. However, the midnight shifts are usually the most undesirable work hours; therefore the mechanics with the least amount of tenure in a company are assigned to that time slot. Due to the undesirable nature of this shift, the morale of the average midnight shift worker is low. The remaining mechanics that needed to work midnight are predisposed to error due to dissatisfaction, nor that they are unqualified to perform the maintenance assigned to them, but rather there is inadequate presence of senior, experienced mechanics to supervise them. Passing incomplete maintenance and inspections to the midnight shift magnifies the potential for error. These impacts can be reduced through careful scheduling of aircraft inspections arranged by the mechanics. They should consider how to balance the needs on physical and mental to the quality maintenance requirements. For example, Engine oil changes (scheduled maintenance) is an example of maintenance that only requires short labour hour and can easily be completed during the day. With less scheduled maintenance assigned to the night shifts, more mechanics are available for a reduced inspection load. So,
