• ED Decision 2023/013/R found in: Initial Airworthiness and Environmental Protection (748/2012) Part-21 Part-21L (Jul 2024)

GM1 21L.A.174(c) Management system for design ED Decision 2023/013/R INDEPENDENT MONITORING FUNCTION The scope of the independent monitoring function is to ensure that: — the management system for design remains compliant with the applicable requirements of the Part 21 Light and with any additional requirements as established by the organisation; — the staff of the design organisation follow the documented procedures of the management system when performing their tasks; and — the management system for design is adequate and enables the organisation through the use of its procedures to provide assurance that the designed products, changes and repairs are compliant with the applicable type-certification basis and the applicable environmental protection requirements. An objective review of the complete set of design-management-related activities is provided through independent monitoring activities, such as audits, inspections, reviews. The independence of the monitoring activities is established by always ensuring that those activities are performed by staff that are not involved in the function, procedure or products they monitor, and that are independent from the operating managers of the function(s) being monitored; however, this should not exclude support by domain experts during monitoring. The monitoring is usually performed based on a monitoring plan. This plan is established to show when and how often the activities required by Part 21 Light will be audited. This plan normally includes, in a defined period of time, all the elements of the management system, including all subcontractors. The defined period of time for the audit planning typically does not exceed 24 months. When a non-compliance is found, the root cause(s) and contributing factor(s) should be identified and corrective actions should be defined and followed up. When providing feedback, the compliance-monitoring function should define who is required to address any non-compliance in each particular case, and the procedure to be followed if the corrective action is not completed within the defined time frame. Also, as required in point [21L.A.174](#_DxCrossRefBm1649097757)(c), feedback has to be regularly provided to the head of the design organisation on the overall status of the compliance and adequacy of the management system for design, including main issues identified and cases where corrective actions have not been satisfactorily implemented. Staff that perform an independent monitoring function should have access to all the parts of the design organisation and, as necessary, to any subcontracted organisations. ##### GM1 21L.A.174(c) Management system for design *ED Decision 2023/013/R* **INDEPENDENT MONITORING FUNCTION** The scope of the independent monitoring function is to ensure that: — the management system for design remains compliant with the applicable requirements of the Part 21 Light and with any additional requirements as established by the organisation; — the staff of the design organisation follow the documented procedures of the management system when performing their tasks; and — the management system for design is adequate and enables the organisation through the use of its procedures to provide assurance that the designed products, changes and repairs are compliant with the applicable type-certification basis and the applicable environmental protection requirements.
