CAA UK issues Aircraft Maintenance Incident Analysis Paper
4 December 2007

The U.K. CAA released the results of an analyses of a selection of maintenance related events on jet aircraft above 5,700kg MTOW, captured and stored under the requirements of the CAA’s Mandatory Occurrence Reporting (MOR). The data showed that the vast majority of MORs were related to Equipment and Furnishings, escape slides in particular. The study concludes that the number of maintenance related MORs as a percentage of the total number of MORs submitted to the CAA appears to decrease steadily from 2000 to 2005. This reduction may, in part, be attributable to the extensive efforts of the CAA to promote human factors awareness training, guidance and policy within the industry. Recommendations include improving the consistency and comprehensiveness of data captured to facilitate future trend analysis, and identification of the underlying causes of maintenance error. (CAA)
