Galley insert modifications

Fleet standardisation is the cornerstone of operational efficiency, ensuring seamless crew operations and delivering an outstanding passenger experience. At Aerospace Engineering Solutions (AES), we specialise in EASA Part 21J-approved modifications for galley insert removal, installation, and replacement, enabling airlines to adapt easily to evolving passenger preferences and operational requirements.

With extensive experience modifying aircraft types such as the Airbus A320, A330, and Boeing 737, AES has supported numerous projects that prioritise safety, efficiency, and passenger satisfaction. Our Part 21J Design Organisation Approval (DOA) empowers us to deliver bespoke engineering solutions tailored to each airline’s unique needs.

Galley inserts, including refrigerators, ovens, and coffee makers, are crucial for delivering in-flight services. However, as passenger demands and operational priorities evolve, airlines must evaluate their galley layouts to ensure maximum efficiency and compliance with certification requirements. Optimising galley inserts offers numerous benefits:

  • Standardise cabin layouts for improved crew efficiency: Uniform galley configurations simplify crew operations, reducing training requirements and improving service consistency across the fleet.
  • Reduce weight by removing underutilised inserts: Eliminating rarely used equipment can significantly reduce an aircraft’s weight, contributing to fuel savings and lower operational costs.
  • Upgrade to lighter, more efficient equipment: Replacing outdated inserts with modern, lightweight alternatives enhances energy efficiency and reduces wear and tear.
  • Align with evolving passenger demands: Adapting to changing customer preferences, such as increased demand for speciality beverages or premium food options, ensures a better passenger experience.

Key considerations for galley modifications 

When updating or adding new galley inserts, the DOA must carefully evaluate several factors to ensure compliance with EASA certification requirements:

  • Connections: Verify that electrical and plumbing systems are compatible with the new equipment.
  • Weight: Assess how the changes impact the aircraft’s weight and balance.
  • Flammability: Ensure materials meet stringent safety standards.

AES’s expert team addresses these aspects meticulously, providing comprehensive support from initial assessment to final approval. Highlighting the value of galley insert optimisation, Lola Lahoz, Design Office Manager – Spain, said:

“By replacing galley inserts, we allow airlines to achieve standardisation and accommodate galley insert types that customers ask for most during flights. In doing so, we reduce weight by removing underutilised inserts and replacing others with lighter options.”

Partner with AES for expert-led modifications

At AES, we deliver fast, safe, and innovative solutions that enhance aircraft interiors. With our EASA Part 21J DOA, we ensure high-quality modifications, competitive delivery times, and seamless customer support. Contact us today at info@aesglobal.co.uk.

Aerospace Engineering Solutions (AES), a leading specialist in aircraft design and certification, is thrilled to announce the successful completion and approval from the European Union Aviation Safety Agency (EASA) for Supplemental Type Certificate (STC) No. 10085153. This STC enables a complete business-class only cabin reconfiguration on an Airbus A321 aircraft.

Headquartered in the UK, with additional operations in Spain and Ireland, AES’s Design Organisation Approval (DOA) team was contracted by beOnd, the world’s first premium leisure airline, to develop a modification that introduces a cabin layout using 34 business class seats, generating a 68-passenger seating configuration. The lie-flat seat motion system is a standout feature in the narrow-body aircraft market.

Key modifications include:

  • Installation of Optimares Vivaldi lie-flat business class seats
  • Integration of the seat motion power system
  • Installation of 110V AC and USB Type C In-Seat Power Supply System
  • Rearrangement of cabin monuments
  • Door 3 exit type re-assigned from Type I to Type III
  • Rearrangement of Passenger Service Units (PSUs)
  • Reconfiguration of emergency equipment and emergency path lighting
  • Updated placards
  • New carpet and cabin attendant seat covers
  • On-site cabin inspections

In addition to the interior reconfiguration, AES also provided the EASA-approved Part 21J technical data package to accomplish beOnd’s stunning signature dark grey and copper livery.

Commenting on this achievement, Andrew Dolby, Director at Aerospace Engineering Solutions, said:

“This latest STC approval reflects our commitment to excellence and reinforces our position as a leader in aircraft cabin reconfigurations. Our team demonstrated exceptional resourcefulness and dedication, overcoming challenges related to material and parts procurement, all while working within a tight time schedule to ensure that the modification was completed and approved on time for our customer. We are thrilled to have partnered with beOnd on their new aircraft and deliver a configuration that will enhance the passenger experience, and we wish them all the success.

“Our vast scope of approval and highly experienced team in cabin interiors, structures, and avionics allows us to provide our customers with any cabin configuration for their fleet.”

Tero Taskila, CEO & Chairman at beOnd, said:

“We are happy to have received the STC for our A321 aircraft, marking the addition of the second aircraft to our growing fleet.
