Posted by caitlinharry on May 16th, 2019

Everyone knows that one of the most critical processes dealing with aerospace management is internal auditing. As this audit is designed to examine the performance of the Aerospace Quality Management System, an organization needs to count on a number of vital aspects. However, we can make your task a bit easier. In this article, we are going to provide you with most-effective tips on how to develop a checklist for AS 9100 internal audit.

Listed below are the tips that can help you make the auditing program easier:

Review of process documents

As the purpose of auditing is to measure the current performance of your Quality Management System against what you had planned, your auditing checklist should start with a review plan for the processes. If you find there is a documented procedure for examining every process, you should ensure that the procedure is able to record the details.

In this context, it important to look after a couple of things, such as:

Updates and improvements

If any changes take place inside the process, you should follow up the process to ensure that every employee, somehow related to the project, was aware of the changes. It assumes great importance when the change made for a particular problem that emerged to prevent its repetition.

Non-modified content

If you forget to update the content of the process for a long time, you should pay some attention to reviewing whether the content is still accurate or not. Sometimes, organizations find a more effective way to manage this stuff; and if you forget to update the process, the written document may not reflect your best practices.

Previous corrective actions

Previous corrective actions are given immense importance in the AS 9100 and ISO 27001 internal audit program. Always remember that an integral part of your checklist will include the checks and modifications, which were reported in your previous corrective actions.

Consider AS9100 Rev D requirements

Is your process documented? Then there are chances that your processes have already been checked when the document got approval. However, it is also important to verify every so often that your process is not missing the requirements of AS9100. It is also important to ensure that the QMS is aligned with AS 9100 Standard. Internal auditing is the best practice for doing this.

Analyze process inputs and outputs

The process is an activity that takes one or more inputs and generates more outputs. Sometimes, you may find that the output of one process may become the input to another process. In such a case, you may face a number of problems arising through the interactions of the processes. Monitoring these interactions is vital when you are going through internal auditing.

Research the overview process

If you don’t have any documentation, then you can develop and monitor an overview of the most useful process. When the process approach was implemented for the first time, many internal auditors prefer using a diagram. This diagram is often called “turtle diagram”. This diagram helps you understand how a process works.

Count on Process of Effectiveness

You should know an indicator is there that should be used for the process owner to explore that the process is running efficaciously and meeting all the objectives and targets, which are planned for the process. By measuring this performance indicator against the expected results, the auditor will be able to tell whether the process has been properly implemented or any further improvement is needed in the procedure to fulfill the targets.

Define the Samples

When it comes to AS 9100 internal audit program, another element assumes great importance- this is defining the sample. It is not possible for everyone to examine every piece of data. That’s why the audit process should depend on a sample for assessing the processes. You should want to identify a way of choosing your sample.

A Final Takeaway

We all know that preparation is a key for successful audit; that is why a checklist is important. Numerous audits have a limited time for accessing the information you need so that you can draft an outline for the internal auditing program.


Before planning for an internal auditing program, you should educate yourself about the standard and its requirements.
