Measuring the Effectiveness of the Aircraft Maintenance Planning Process

Major Factors to consider include the measurement of the value of the maintenance process.

• How much is the maintenance costing per man hour
• How effective is the maintenance performed – reference to reliability reports
• What are the opportunities for optimization of the existing maintenance program
• Does the SB evaluation and embodiment process add value to the maintenance process
• How effective is the communication process in respect of the performance of the maintenance

We should be able to consider and measure both short term measures as well as longer term, which will allow a longer term measure of the company profitability.

Developing KPI’s for Maintenance

KPI’s are essential for evaluating the effectiveness of the maintenance which is performed. A KPI is an indicator typically of the product of multiple measures (metrics)

The selection of KPI’s can relate to many different elements and aspects including financial – efficiency of the process – health and safety (SMS) considerations – defects and pilot reports (PIREPS) following maintenance.

Once a detailed assessment has been made it is possible to consider which are the most relevant indicators applicable to the delivery of the most effective maintenance.

How do these indicators relate to each other and do they meet the requirement?

Is the measurement process of the chosen indicators effective?

When developing KPI’s it is important that they relate to the entire process including the various inputs and outputs so that they are able to genuinely benchmark the performance of the maintenance.

Factors to be considered include the following:

• Individual productivity;

• Training and Competence Management processes;

• Culture and Safety behaviour within the organisation;

• Provision and effective use of the Maintenance budget;

• Stores, material and tool control management and optimisation;

• Engineering Reliability and on condition processes;

It is important to consider the maintenance process in detail before jumping into specific elements.  This may be accomplished by mapping the entire maintenance process and identifying any gaps between the perceived optimum maintenance planning and the actual delivery.

KPI’s may be time or goal based or provide trend information providing ongoing status of the effectiveness of the maintenance process.

We need to make sure that the KPI is delivering information we can act on and is not simply generating data with limited value.

Essential Maintenance KPI’s have 3 aspects which we need to focus on:

• Design
• Implementation
• Consideration and Analysis of the acquired Data

Ultimately the Maintenance KPI process needs to provide the Management team with the data necessary to support the most effective decision making to benefit the organisation.

Therefore the involvement of stakeholders during the “construction” phase is of direct benefit.
