Aircraft Engineering Change Workflow
How a change to an aircraft design is proposed, assessed, approved by the airworthiness authority and put into production.
Drawing diagram…
What this diagram shows
- Every change is classified as minor or major
- Major changes need approval from the aviation authority
- Affected parts and aircraft are traced by serial number
Prompt used
Aircraft engineering change workflow: an engineering change request (ECR) is raised. Engineering assesses impact on safety, weight, cost and certification and classifies it as minor or major. Major changes need approval from the airworthiness authority (DGCA/EASA/FAA). Approved changes are released as engineering orders, drawings are updated in PLM, production and suppliers implement them, and affected aircraft serial numbers are tracked.
