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  • Upgrade to lighter, more efficient equipment: Replacing outdated inserts with modern, lightweight alternatives enhances energy efficiency and reduces wear and tear.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.”

Boeing 737NG cabin configurations

Is your Boeing 737NG cabin configurations in compliance with EASA regulations?

In response to the Certification Memorandum CM–21.A–CS–001 Issue 02, titled “Classification Of Design Changes To Cabin Interiors Of Large Aeroplanes,” released by EASA in April 2021, AES has successfully secured six Supplemental Type Certificates (STCs) for various seat type configurations on the Boeing 737NG, covering both 186 and 189 passenger configurations. Notably, the most recent STC covers the Safran Z100 series in a 189 configuration (STC Nr 10083547). AES is actively pursuing additional STCs, with several applications currently in progress.

The Certification Memorandum clarifies classification of changes to Cabin Interiors including the installation of seats that require a compliance statement against CS25.562, focusing on Emergency Landing Dynamic Conditions. It’s worth noting that this requirement has been a longstanding part of EASA Part 21 Appendix A of GM 21.A.91. However, with the release of CM–21.A–CS–001, EASA has clarified and reinforced the classification process for such changes, superseding past practices.

A key aspect highlighted in accordance with EASA B737 Type Certificate Data Sheet (TCDS) IM.A.120 is that most seating configurations for the B737NG family must meet the requirements for JAR25 Chapter 13, excluding certain clauses. This mandates the classification of these changes as Major (STC). It is important to mention the requirement provided in CS26.60 (Additional Airworthiness Specifications), which requires dynamically tested seats to be installed in configurations manufactured post-26th February 2021 to be compliant with CS25.562.

AES remains committed to delivering aerospace engineering solutions that not only meet but exceed regulatory requirements, ensuring the highest standards of safety and compliance in the aviation industry.
