Designing an air ambulance interior requires more than fitting medical equipment into an aircraft. The mission system must support patient access, clinical workflow, crew safety, equipment visibility, emergency egress, electrical demand, weight and balance, maintainability, and airworthiness compliance.
Gama Aviation designs and delivers air ambulance mission-system modifications for fixed- and rotary-wing aircraft, including Textron King Air, Airbus H145, and Leonardo AW169 platforms. Our UK CAA Part 21J Design Organisation works with clinical, operational, flight, maintenance, and OEM stakeholders from initial requirements and feasibility through design review, testing, certification, production, installation, and in-service support. This work is conducted under UK CAA certificate UK.21J.0174 and includes privileges concerning major/minor classification and the approval of minor changes.

We develop mission systems around the aircraft, medical equipment, operating concept, clinical workflow, and regulatory route—not around a predetermined interior. Depending on the mission, the solution may include patient-loading and stretcher systems; medical-equipment mounts and cabinets; oxygen storage, suction, power, and lighting; NVIS modifications; communications and data systems; infection-control partitions; flooring; and configurable role-fit equipment.
Our work includes:

Too often we hear from those who have commissioned aviation mission system design projects only to find that a simple Minor Change has turned into a monster project.
We are firmly of the belief that engaging in open and honest discussions with all stakeholders helps us to set clear expectations and provide expert guidance from the start, avoiding the problem of scope creep. To assure a timely, planned and controlled process we aim to assist our customers in making the correct design decisions using our established methodology, whilst ensuring compliance with all regulatory, statutory and legal requirements. Our design process is defined by gateways as illustrated below.

We see our job as a partner to the Charity, helping you to navigate the design process to ensure that your Air Ambulance is fit for purpose, both now, and long in to the future.
From complete interior refurbishments to a simple LED lighting upgrade we have it covered. We have a wealth of experience in Cabin Interior modifications with many “off the shelf” design solutions ready to be installed.
We also design and manufacture bespoke bulkheads, monuments and stowages to meet our clients’ needs to store medical equipment.
Typical Air Ambulance Interior projects undertaken by our Design & Production Team include:
Using the latest 3D Computer Aided Design (CAD) software, our team are ready to support you in all of your mechanical design needs. The team are experienced in all aspects from technical survey, initial hand calculations, through detail design development to creation of production drawings and computer aided manufacturing data.
Examples of projects and additional services covered by our Mechanical Team include:
Using the latest Electrical Computer Aided Design (ECAD) software, our team are ready to support you in all of your electrical design needs. Modifications and repairs with electrical aspects will involve numerous assessments, such as power distribution, electrical load analysis and electromagnetic compatibility.
Typical projects undertaken by our Electrical Team include:
Our assembly shop floor has been laid out to ensure that the creation and production of parts follows a lean process. We have the capability to assemble components of any weight and size both mechanical and electrical. All assembled parts are fully inspected and released with either a Form 1 or C of C.
Typical assembly work undertaken by us includes:
As an approved design and production organisation certification is at the heart of everything we do here at Gama. We are experienced in producing both Major & Minor Changes and Repairs that are either approved or accepted by the various National Aviation Authorities (NAA’s) across the world.
With over 1700 Minor Changes & Repairs and 70+ STC’s within our portfolio we often have an off-the-shelf design solution to fit your particular needs.
However, we also realise that not every aircraft is the same and every project is different, if we don’t have a pre-existing design we have the capability and approvals to produce a new Change or Repair to support your particular aircraft and operation.
Our core certification activity includes:
