An Analysis of MH-53E Aircraft Maintenance Manpower in Japan Maritime Self-Defense Force (JMSDF)
Abstract
The author examines the MH-53E helicopter maintenance policy in view of the JMSDF's concern. The maintenance data from December 1989 through June 1993 was examined using descriptive statistics and multiple regression analysis. In particular, the manpower reallocation, learning-effect and adequacy of spare- parts are discussed in this context. The study indicates successful maintenance practice in reducing the unscheduled maintenance hours and awaiting supply hours. A statistically significant learning effect was not observed using the existing available data set. The regression analysis has identified statistically significant factors that explain the behavior of the mission- capable hours and the maintenance-work hours. Two policy recommendations are formulated: The first is a need for a more flexible manning policy that reflects and incorporates the actual maintenance experience and requirement. The study proposes a more dynamic and flexible manning policy based on actual requirements and experience. The second recommendation deals with a need for more detailed costs and manpower data to achieve MSDF-wide cost-effective resource allocation. For the maintenance policy to be cost-effective, it is imperative to develop such a data set.
