Aerospace cable assemblies for onboard equipment and systems
We work with manufacturers and integrators who need aerospace cable assemblies, connectors or contacts for onboard equipment and systems, defined by interface, application and project requirements. We keep the rule that already defines us: we check with the manufacturer what can be met before quoting, and we say no when the requirement falls outside what the network can demonstrate.
What this industry needs
What changes in aerospace cable assemblies
“Aerospace” does not by itself define the requirement for the cabling. The internal cabling of a piece of equipment is not the same as the interface between that equipment and the platform. Nor should an aeronautical application and a space application be taken as equivalent: the environment, the process required and the evidence to be provided can change. What does not change is the order: our first response is to check what documentation really accompanies the material, not the price.
- Application and platform the assembly is intended for
- Whether the assembly is internal to the equipment or an interface with the aircraft cabling
- Environment conditions expected for that application
- Process, tooling or approval requirements imposed by the project
Industry requirements
What to define in aerospace cable assemblies
Each project can require different criteria and they are confirmed with your documentation before quoting. If it defines requirements derived from AS50881 —wiring of aerospace vehicles and its interconnection system— or other applicable aeronautical interconnection specifications, they must be carried into the assembly and to the manufacturer that will make it.
- Drawing, interface and function of the assembly
- Cable, contact and connector specified
- Workmanship criterion and applicable process
- Inspection, evidence and documentation required
- Manufacturer approvals or quality requirements
Where we step in
Where our aerospace cable assemblies come in
We are a supply channel, not a qualified supplier of the sector: the specification is defined by the customer, and the manufacturer makes the assembly and carries out the agreed checks. That distinction is the starting point.
Onboard equipment and subsystems
Assemblies, connectors and contacts for aeronautical equipment and subsystems, according to the specification of the manufacturer or integrator.
Interface between equipment and platform
The defined assembly that connects the equipment to the platform cabling. We do not design the aircraft EWIS: we supply the assembly the customer has defined.
Internal interconnection of equipment
Harnesses and leads inside the equipment itself, when governed by aeronautical project requirements: environment, process, evidence or manufacturer approval.
Replacement and controlled change
No part number is changed without your express, documented authorisation. If a part number is no longer available, we compare potentially compatible alternatives and tell you the relevant differences before you decide.
Two applications, two requirements
Aeronautics and space do not demand the same from the cabling
The application determines the requirements. The internal cabling of a piece of equipment, the interface between that equipment and the platform and a space application can require different environments, processes and evidence.
Application and environment
The platform, the location and the function determine the conditions the assembly must withstand. The internal cabling of a piece of equipment and the interface between that equipment and the aircraft are not necessarily subject to the same requirements.
Interconnection and process
Cable, contact, connector, protection and termination must match the specification. When the project requires controlled or qualified tooling, processes or operators, that capability must be confirmed with the manufacturer.
Evidence and acceptance
Certificates, traceability, inspections, first article or other evidence must be defined before quoting. The manufacturer generates the documentation that corresponds to it and Justicia Marin coordinates its availability and supply.

How we work for this industry
How we coordinate aerospace cable assemblies
The process is designed to rule out early what we cannot cover.
We receive the complete requirement
Application, platform, drawing or interface, and the documentation or processes required by your customer or your quality system.
We check before quoting
We consult real availability, documentation and process capability with the manufacturer or the originating distributor.
We answer clearly
We quote only what the network can cover with the documentation required; the rest is explicitly ruled out.
We supply with control
The manufacturer makes the assembly, controls the processes required and carries out the agreed inspections. The delivery keeps the agreed batch documentation and does not incorporate unauthorised variations.
What we actually do in this industry
Justicia Marin is a distributor: it supplies components and coordinates assemblies through a network of manufacturers. We hold no qualifications, approvals or endorsements of our own in this sector, and we do not declare compliance with any specific standard in a generic way. When your project requires a certification, a qualified process or specific documentation, you tell us and we confirm before the order what the network can really provide and what falls outside our scope — in writing, in the quote. Specifically: Justicia Marin is not a qualified supplier in the aerospace sector, holds no approvals or accreditations in this field and does not carry out special processes. Our scope is limited to the supply of components whose documentation can be verified with the manufacturer. Any requirement that calls for supplier qualification falls outside it and is communicated before quoting.
When the project requires a controlled interconnection process, the tooling, process, inspection or qualification requirements that apply to the manufacturer who will make the assembly must also be defined. If it requires first-article inspection or equivalent documentation, this must be defined before quoting and confirmed with the manufacturer. And if it requires manufacture by a manufacturer with EN 9100 or other customer-specific approvals, that condition is confirmed before quoting. Nor do we design the aircraft wiring or carry out installation or maintenance on the platform.
Questions from aerospace
Aerospace cable assemblies: frequently asked questions
- Do you supply cable assemblies for aircraft and satellites?
- We supply assemblies, connectors and contacts for aeronautical and space equipment, to the specification of the manufacturer or integrator, but only if selected manufacturers can demonstrate the required documentation and processes. We do not design aircraft wiring and provide no installation or maintenance on the platform.
- Is Justicia Marin a qualified aerospace supplier?
- No. We hold no approvals or accreditations in aerospace and carry out no special processes. If your project requires a manufacturer with EN 9100 or another approval, we confirm before the quote whether such a manufacturer is available. If not, we say so straight away rather than trying to resolve it later.
- Which standards are relevant for aerospace wiring?
- A commonly used reference is SAE AS50881 for the wiring of aerospace vehicles, alongside manufacturer and customer specifications. Which requirements apply is determined by the project; we include them in the specification sent to the manufacturer and confirm in writing what can be documented.
- Can a first-article inspection be supplied?
- If the project asks for a first-article inspection or equivalent documentation, we record that before the quote and confirm with the manufacturer whether it can prepare it. The manufacturer produces the documentation that belongs to its process; Justicia Marin coordinates its availability and delivery.
- How are changes to an aerospace assembly managed?
- No part number is changed without your express, documented permission. If a component is no longer available, we compare potentially compatible alternatives and present the relevant differences. You decide; only then is a new configuration recorded and delivered, so that no variation ever reaches your equipment without your approval.
- What do you need for a quote?
- The application or device, the drawing or interface, the specified cable, contacts and connectors, the workmanship criterion, the inspections and documentation required, any approvals required of the manufacturer, the quantity and expected repeat orders. With that information we check with manufacturers and answer clearly.
- Why can a request be declined?
- Because we only quote what selected manufacturers can really cover with the documentation required. If a project asks for a qualified process or an approval that is not available, we rule it out explicitly. That is more honest than accepting an order that later fails to meet the requirements.
