Quality Audit: CAR-145 Organisation Audit Process & Requirements


Organizations that have been issued a CAR 145 Certificate of Approval must undergo a CAR 145 organization audit every year or as per planned. This audit determines if the organization continues to meet the requirements of the CAR 145 Standard. This document outlines the important points to look for in a CAR 145 organization audit.


What is Audit?

When it comes to business, an audit is a comprehensive examination of a company's financial records. The goal is to ensure that the financial statements are accurate and that the company is in compliance with the law. The most common type of audit is the financial audit, which examines a company's financial statements. 

But a CAR 145 organization audit is a bit different. A CAR 145 audit is an examination of a company's safety management system. The goal is to make sure that the company is taking the necessary steps to ensure the safety of its employees and the public. The audit examines the company's policies, procedures, training and management systems.


What is a quality Audit in General

Quality audits ensure that products and services meet specific requirements and are consistent with customer expectations. They verify that the product or service is manufactured, processed, packaged, labeled, stored, and shipped according to the design specification. A quality audit also looks at the operational processes to make sure they are effective and efficient. Furthermore, quality audits assess customer satisfaction, as well as employee satisfaction.


What is a quality Audit in terms of Aviation Maintenance & Operations?

A quality audit is an evaluation of the quality system applied in an organization. The aim of the audit is to identify any deficiencies in the system and recommend corrective action. The aviation industry relies on a strict and well-defined quality system to ensure the safety of passengers and crew. A quality audit is essential to maintaining this safety record and preventing accidents. A quality audit can help airline operators identify any areas of weakness in their quality system and take corrective action.


Why we do audit?

A CAR 145 organization audit is an important process that ensures your company is compliant with aviation regulations. It also helps to identify any areas where improvements can be made. There are five key aspects that are looked at during an organization audit: organizational structure, management procedures and systems, operational procedures, training and qualification, and resources. By having a clear understanding of each of these areas, your company can be assured that it is meeting all the necessary requirements and is in compliance with aviation regulations. A qualified auditor will review your systems and procedures and provide a detailed report of their findings.

As per the DGCA requirements, the CAR-145 organisation must have Independent audit systems. The independent audit is an objective process that includes routine sample checks of all aspects of the organization's ability to carry out all maintenance to the required standards, as well as some product sampling as the end result of the maintenance process. It is intended to supplement the 145.A.50 (a) requirement for certifying staff to be satisfied that all required maintenance has been properly carried out before issuing the certificate of release to service. When performing maintenance, independent audits should include a percentage of random audits performed on a sample basis. For those organisations that work at night, this means some audits during the night.

Audit Frequency

Organizations that have been issued a CAR 145 Certificate of Approval must undergo a CAR 145 organization audit every year. This audit determines if the organization continues to meet the requirements of the CAR 145 Standard. This document outlines the important points to look for in a CAR 145 organization audit. 

The independent audit should ensure that all aspects of CAR-145 compliance are checked every 12 months and can be performed as a single exercise or subdivided over the 12 month period in accordance with a scheduled plan. The independent audit does not require that each procedure be checked against each product line if it can be demonstrated that the particular procedure is common to more than one product line and that the procedure has been checked every 12 months with no results. 

When findings are identified, the specific procedure should be rechecked against other product lines until the findings are corrected, at which point the independent audit procedure for the specific procedure may be reduced to 12 monthly.


Why is an organization Audit important?

An organization audit is an important process that should be conducted regularly in order to maintain compliance with CAR 145 and identify any areas of improvement. The goal of an audit is to identify any deficiencies in the organization's policies and procedures and to recommend solutions. An organization that conducts regular audits is able to ensure that its employees are properly trained and its systems are effective and compliant.


When does my organization need an Audit?

Many organizations choose to have an annual CAR 145 organization audit to ensure compliance with the requirements of the standard. However, there may be other circumstances in which an organization would need to conduct an audit. For instance, if there is a change in management, opening of new base, opening of new line stations, selection of new vendor, induction of other type of aircraft, components maintenance, if the organization experiences a data breach, or if there is a suspected compliance issue, an organization would need to conduct an audit.
