The maintenance task development is

The maintenance task development is referred to the reliability center maintenance analysis (RCMA),
which is a system engineering covering from aircraft design to maintenance. MSG-3(maintenance
steering group 3) [11] is the methodology used to execute the philosophy. So the MSG-3 method is an
important direction to develop the maintenance task, which is based on system or subsystem function
reliability philosophy, and the applicability, safety effectiveness, operational effectiveness and economic
effectiveness are emphasized by MSG-3. The maintenance methods are included such as
lubrication/servicing, operational/visual, inspection/functional, restoration, discard, and combination. And
the cost and difficulty of achieving the task is higher and higher with the airworthiness standard
requirement and maintenance task rise of methods level. The main purpose of MSG-3 maintenance is
more safety, satisfaction reliability and better economy, so it is called safe, reliable and economic
maintenance methodology. In this paper, the maintenance task development is directed by MSG-3.
