The Effect of Line Maintenance Activity on Airline Safety Quality

This paper examines the quality of airline line maintenance activity and whether the level of maintenance spending has an effect on maintenance quality and overall safety. Service Difficulty Reports, which are the publicly available record of line maintenance activity performed at repair stations, are examined for the major U.S. carriers. Data on safety outcomes were gathered from Federal Aviation Administration safety databases on accidents, incidents and near midair collisions. Information on maintenance spending for 10 major U.S. airlines was collected from U.S. Department of Transportation air carrier financial statistics. Results of this analysis indicate that, in general, increased maintenance spending is associated with both increased line maintenance activity and increased overall safety quality.
