An aircraft lessor or airline typically looks for certain qualities in a DOA holder and there are many factors they consider important:

  • Compliance: The DOA holder should have a strong track record of compliance with regulatory requirements and standards set by aviation authorities. This ensures that the designs and modifications performed by the DOA meet safety and airworthiness standards.
  • Expertise and Experience: The lessor or airline will value the DOA’s expertise and experience in aircraft design, modification, and engineering solutions. A proven track record of successfully completed projects and a team of skilled professionals contribute to the DOA’s credibility.
  • Technical Capabilities: The DOA should possess the necessary technical capabilities and infrastructure to handle the lessor’s or airline’s specific requirements. This includes having appropriate design tools, software, testing facilities, and qualified personnel.
  • Flexibility and Responsiveness: The lessor or airline would prefer a DOA that can adapt to their needs and provide timely responses. Flexibility in accommodating modifications, efficient communication, and prompt delivery of design solutions are valued traits.
  • Cost-Effectiveness: While quality and compliance are crucial, the DOA’s pricing and cost-effectiveness also play a role. The lessor or airline will consider the overall value proposition, including the DOA’s pricing structure and competitiveness in the market

Ultimately, the Aircraft Lessor’s DOA expectations is to provide reliable, compliant, and cost-effective engineering solutions, ensuring the airworthiness and safety of their aircraft fleet.

Leading aircraft design and certification specialist, Aerospace Engineering Solutions (AES), is powering into 2023 with the launch of a new office in Malaga, Spain, as the company embarks on a phase of international expansion.

Trading as AES Spain, a wholly-owned subsidiary of AES, the new operation will enable the business to develop new partnerships with commercial and private aviation clients across Europe, which will benefit from the unrestricted level 2A Design Organisation Approval (DOA) capability held by AES.

Located at Malaga’s state-of-the-art business incubator technology park, BIC Euronova, AES Spain is the first DOA in Malaga and only the second in Andalucía. The new operation has also become a member of the Andalucía Aerospace cluster of more than sixty aerospace companies based in the region, for the purpose of fostering technological developments, potential project collaboration and strengthening its international presence.

In addition to a team of highly skilled design engineers, AES Spain has recruited two aerospace engineering graduates from the University of Malaga, as part of the company’s commitment to future-proofing its skills base.

Speaking at the launch of AES Spain, Anton Heissig, Director and Head of Design, said:

“The launch of our new office in Malaga is testament to the support of all the AES team, shareholders, clients and partners, which has enabled us to expand our international capacity as part of the company’s strategy for growth. We are proud to be the first DOA based in Malaga, which gives AES a solid footing in Europe and a deeper integration with our continental partners.

“We are also delighted to welcome new Spanish personnel onboard and look forward to building partnerships within the Andalucía Aerospace cluster, which we see as a valuable network for growing our presence within the European aviation community.”

Lola Lahoz, Malaga Design Office Manager and Deputy Head of Office of Airworthiness, commented:

“Our new DOA Office in Malaga provides an excellent base to build the profile and capacity of AES internationally, both in civil and military aviation markets. BIC Euronova is the ideal environment to help AES expand its expertise in aerospace certification with current and new business sectors such as drone certification in collaboration with the Andalucia Aerospace cluster.

“We also aim to further develop links with Spanish universities and build a base to forge links in other Spanish speaking countries in South America.”

Offering a wealth of experience repairing and refurbishing commercial aircraft interiors has led Jetglow Aircraft Refurbishments to identify several high-volume replacement parts and make significant savings on OEM costs to airline operators.

Alongside their carefully chosen Part 21J design partner – Aerospace Engineering Solutions – both companies have developed from concept to delivery Boeing 737 aftermarket scratch panes for cabin sidewall panels available for release on a Form 1 under Jetglow’s Part 21G approval. By bringing manufacturing capabilities to the UK, both companies can build on opportunities for the local market as well as saving airline’s significant costs.

The product – a protective screen used to eliminate airline passengers from touching the pressurized window, not only adds a layer of protection against contaminants but prevents passengers from touching sensitive areas of the aircraft.

Using CS25.853-compliant materials from carefully sourced suppliers and the collaboration of both companies’ capabilities with their highly skilled craftmanship and certified approvals, these high-volume replacement parts can be manufactured and supplied to airlines and MROs at aftermarket prices.

Jetglow Aircraft Refurbishment’s Technical Manager, James Lowrence comments:

“We’re delighted to be able to draw on our experience and expertise to offer aftermarket parts and complement our existing services to airlines and MRO’s – by acting as a one-stop-shop we’re in a great position to reduce costs for our customers.
