Development of a tool for access worktime estimation in aircraft maintenance

This study was aimed to find a way how to deal with hardly predictable circumstances while performing routine access works during aircraft heavy maintenance and to estimate the time spent with the work. The lack of maintenance data was crucial in dealing with this issue, therefore, additional measurements were necessary. For this purpose, this study was done in cooperation with Czech Airlines Technics Maintenance Repair Organization. The company currently estimates timing of panel manipulation based on the information contained in the manufacturer’s documentation. A database was established with work measurements of maintenance technicians accessing panels during real aircraft maintenance. They should by their nature reflect complications arising during the access panel manipulation and of the specific operational factors in the company. The main importance of the database lies in the creation of additional data to refine the aircraft maintenance planning estimates. Based on the measurements, it was possible to demonstrate that the access panel manipulation times as stated in the manufacturer’s documentation are only indicative. For each measurement performed, the measured overall time of panel manipulation was much higher than the equivalent time estimates by the manufacturer. During the measurements, several other factors were also discovered as causal to differences in the manipulation times. The database served as the basis for a developed software tool providing more accurate estimates of access panel manipulation times and resulting in more accurate estimates in maintenance planning in the Czech Airlines Technics, although the results are well reusable with other Maintenance Repair Organizations.
