As an Authorised Engineering Organisation (AEO), we are an efficient and professional partner whose focus is our customers’ success and safety.
Investigative and problem solving capabilities are the foundation of our engineering services. Combined with outstanding engineering competencies, we offer innovative design solutions to satisfy all aspects of all demands – specifications, reliability, time and budget.
Tools
Better customer component reliability and affordability is achieved through innovative applications engineering. Customers rely on us for our core engineering expertise in aeronautics, mechanics, hydraulics, pneumatics, materials and processing.

ENGINEERING
As a DASR Part 21J Design Organisation, we deliver engineering solutions that support the design, continued airworthiness, and operational capability of Defence aviation systems. We are committed to providing compliant, innovative, and cost-effective outcomes that meet customer requirements while maintaining the highest standards of safety, technical integrity, and regulatory compliance.
Our engineering services combine rigorous technical analysis, systematic problem-solving, and a robust Design Assurance System to develop practical, risk-informed solutions that satisfy airworthiness, performance, schedule, and budget requirements.
Design Capability
As a DASR Part 21J Design Organisation, Rosebank Engineering delivers safe, compliant, and innovative engineering solutions that support the design, certification, modification, repair, and continued airworthiness of Defence aviation products. Our multidisciplinary engineering team provides expertise in aeronautical, mechanical, hydraulic, pneumatic, materials, manufacturing, and repair engineering.
Design Assurance System
Our Design Assurance System complies with the requirements of DASR Part 21J and provides the governance framework for all design activities. It integrates competent and authorised personnel, approved design data, controlled engineering processes, design verification, and configuration management to ensure all engineering outputs satisfy applicable airworthiness and regulatory requirements.

Safety and Airworthiness
Safety is integral to every engineering activity. Our Safety Management System is embedded within our Design Assurance System and supports the systematic identification, assessment, and management of safety risks throughout the design lifecycle. This ensures engineering decisions maintain airworthiness, technical integrity, and compliance with
Defence regulatory requirements.
Design Engineering
We provide design, analysis, substantiation, certification support, repair development, and manufacturing engineering for Defence aviation systems. Using advanced engineering and analytical tools, we develop practical, risk-informed solutions that are verified, controlled, and fully traceable throughout the product lifecycle.
Continuous Improvement
Continuous improvement is embedded within our Design Assurance System. Through
design assurance activities, internal audits, lessons learned, and performance monitoring,
we continually enhance engineering quality, process efficiency, and customer
responsiveness while maintaining compliance with DASR Part 21J.
