ASSET’s TCU audits clients in the industry—airlines, charter companies and aerodromes— to measure their operations against international regulations and operating standards. But we don’t stop with the audit; we start with it, and work with you to help you discover new ways to fly smarter, safer.

Our approach to aviation auditing is cooperative; with you we fashion sophisticated audit plans, tailored to your capacities and goals. We help you move beyond compliance toward elegance and excellence of operation and service, on the ground and in the air.
To us, the auditor is the crash investigator before the crash occurs. The audit is a critical component of any assurance program. Aviators are used to being checked — whether by government compliance audits, internal quality checks or performance measures, or third party assurance programs—aviation relies on audits and they are commonplace in our industry.

This is how we go about conducting critical safety and quality audits in aviation.

Our Audit process

We follow the International Auditing Standard 19011 when conducting our audits.

ISO defines an audit as a systematic, independent and documented process for obtaining audit evidence and evaluating it objectively to determine the extent to which the audit criteria are fulfilled.

An audit is a type of investigation that is:

  • Systematic: An audit is well planned, organised and controlled. It is conducted in a logical and methodical manner.
  • Independent: An audit is objective and unbiased—the results are not founded on opinion or hunch, but based on objective analysis and facts. The auditor is independent from the process being audited.
  • Documented: It requires information to be put into writing, to be recorded, so that others can read and follow the process and understand what was achieved and what is needed for the future. A documented process can be measured—

A systematic, independent and documented process can be measures–if you can measure something, you can track its performance. This is how our audit process improves systems, improves safety and improves the industry.

What are our auditing principles?

There are six fundamental auditing principles all qualified auditors should know and practice:


Our auditors must be trustworthy and ethical.

Fair presentation

Our auditors must give a complete and accurate report.

Due professional care

Our auditors must demonstrate sound judgement and professionalism.


Our auditors must ensure information collected during an audit is protected from unauthorised access and use.


Our auditors must be independent of the activity being audited and remain impartial throughout the audit.

Evidence-based approach

Our auditors must ensure that the audit evidence is true and accurate.

We ensure our auditors follow these principles through policy, written procedures, careful selection and recruitment of our audit teams—to get the right people with the right attitude. We use effective competency-based training and continuous professional development, and we carefully check each report.

How do we conduct an effective audit?

We use appropriate audit techniques—there are many available in the auditor’s toolkit: reviewing documents, interviewing people or observing what they do. But these methods alone will not lead to effective audits unless our three key principles guide them:

We target critical areas.

We spend our auditing resources wisely—concentrating on those areas that hold the highest risk to the organisation.

We sample intelligently.

We sample materials—manuals, records, documents—that directly relate to the audit’s objective, its scope and criteria.

We create effective audit trails.

We map a process from start to finish, then follow the trail to critically test the effectiveness of controls.
