Towards condition based maintenance for EMCS
Fokker Service is a Dutch maintenance company with headquarters in Hoofddorp. The company provides maintenance, modification, and repair service for aircrafts like Boeing, Embraer, and Fokker aircrafts. Our case study in Fokker Service focuses on promoting condition based maintenance (CBM) for Electro Mechanical Components (EMCs). For the maintenance of EMCs, Mean Time Between Unscheduled Removals (MTBUR) is a key performance indicator. Operators ask for an annual improvement on MTBUR, while Fokker Service also wants to outperform by providing longer MTBUR. One way to achieve this goal is to promote CBM practices so that an EMC will be removed when its condition reaches a certain limit (detected by condition based monitoring techniques). Such limit is before an unscheduled removal, so less EMCs will experience unscheduled removals. For EMCs experiencing unscheduled removals, MTBUR will become longer.
