Maintainability Index Model Data Base Study.

Abstract

This report presents a review of ten years of aircraft maintenance data and its effects on mathematical modeling. A maintainability Index Model (MIM) was previously developed using 3-M data from the 1975/1976 time period. Since then, maintenance data for the aircraft used to develop the MIM has increased resulting in the model under predicting current year data by 40% and life cycle data by 18%. Because of the variability and instability of 3-M data, a recommendation is made to update the model annually on an interim basis through the use of Maintenance Inflation Factors and to provide a complete update of the MIM data base every five years.
