Part 146 - Aircraft Design Organisations - Certification

This compilation of the above Civil Aviation Rule was made by the Civil Aviation Authority as a reference document to provide details of the current rule requirements. It is not the official version of the Rule and should only be used as a reference document. It does not contain the statement specifying the Rule Objective, and the Extent of Consultation.

Rule brief

The purpose of Part 146 is to prescribe the certification requirements for organisations wishing to conduct aircraft design activities in New Zealand and the operating requirements for the continuation of this certification. Aircraft design activities in relation to this rule part include designs and design changes for aircraft, engines, propellers, their components, and appliances. This rule part should be read in conjunction with Part 21.

The approach is to apply the fundamental principles that design organisations should have the capability to determine the compliance of designs with the airworthiness requirements and should provide certifications for that compliance. To support its activities an organisation is required to provide an exposition that includes evidence of an internal quality assurance system, a design assurance system, staff information, and its proposed activities.

Part 146 adopts the standard layout for the rule parts relating to the certification of organisations. The layout prescribes specific requirements for the certification (entry standards), operation (continued operations), and safety audit (surveillance) of persons carrying out design activities.

Part 146 also provides details for the delegation of the Director’s power to approve design changes. Part 21 requires that all designs and design changes be approved by the Director of Civil Aviation but the approval of designs can be delegated to other acceptable persons under the Civil Aviation Act 1990. Part 146 provides details of the qualifications and experience required for a person to receive a delegation to approve design changes.
