Abstract :
To assess the problem of human errors in aircraft maintenance, material was collected by observation, informal interviews and incident data analyses. The military setting provided diversity including different levels of maintenance, different aircraft (rotary- and fixed-wing), and different ranks of personnel in differing social and economic positions at various military stations. The collection of incident data may report “human factors” as a cause of the problems, but does not expand on the actual factors involved. The observations of, and discussions with, the aircraft maintenance personnel provided information about those actual factors that affect military aircraft maintenance. Many factors were considered with respect to their effect on performance. The lack of spare parts was perceived to be one of the biggest problems
