condition.
PURPOSE
•To ensure realization of the design level of safety and
reliability of the equipment.
•To restore safety and improvements reliability to their
design levels when deterioration has occurred.
• To obtain the information necessary for design of those
items whose design reliability proves inadequate.
•To accomplish these goals at a minimum total cost,
including maintenance costs and the costs of residual
failures.

MAINTENANCE PLANNING DOCUMENT (MPD)
The MPD document provides maintenance planning
information necessary for operators to develop a customized
maintenance program.
The document lists all recommended scheduled maintenance
tasks for every aircraft configuration.

PROGRAM DEVELOPMENT
MAINTENANCE CHECK PACKAGING
BLOCK MAINTENANCE PROGRAM
Grouping the routine task cards according to the time interval
prescribed in the maintenance program as check A ,C and D.
Advantages: Simplifies planning & scheduling of work packages,
Adequate time to perform modifications.
Disadvantages
Variable manpower requirements, Longer grounding time
PROGRAM DEVELOPMENT
MAINTENANCE CHECK PACKAGING
PHASED MAINTENANCE PROGRAM
Schedule portions of its heavy maintenance tasks equally over
the appropriate number of C-Checks.
Advantages: Even out the maintenance workload over time,
shorten the length of each period of down-time.
Disadvantages: Increases planning and scheduling , Limited
time for completion of modifications.
