Part families

Two domains, five part families — and nothing else by accident

Cabin interior work and brake heat sink work look unrelated until you ask who holds the approval. Both are narrow fields with deep process discipline, and both are built to the holder's drawing. Staying inside these five families is what makes a first article predictable; taking on everything is how a programme ends up with a concession at every gate.

Domain A · Family 01

Seat components

Frames and legs, pans, armrests, tray table hardware, recline and track fittings, and the small parts that decide whether a seat feels solid after ten years.

Domain A · Family 02

Galley & lavatory

Inserts, latches, hinges, work surfaces, vanity units, sink hardware and the stainless that has to survive cleaners, spills and a wet environment.

Domain A · Family 03

Panels & liners

Sidewalls, ceiling panels, bin closeouts, window reveals and class dividers, where weight, FST performance and fit all pull in different directions.

Domain B · Family 04

Carbon brake discs

Carbon heat sink discs handed over at the process stage you specify: at agreed density, machined, treated, or as a riveted stack, with the metallic hardware used in riveting.

Domain B · Family 05

Steel brake & wheel

Rotor discs, friction pads and linings, disc cores and backing structures, plus brake and wheel accessories, produced and delivered to your requirements.

Why there is no part number list on this site

A list, a search box and a stock figure are three ways of saying the same thing. We are not saying it.

A published part number list is a stock position, or an attempt to look like one. Neither describes what this site does. Contract manufacturing is quoted against a drawing and a programme; it has no catalogue to browse.

The practical consequence is simple: send the number you care about, and you get an answer for that number — with the process, the tooling position and the release path. That is a better answer than a list would give you anyway.

If a number is not in our wheelhouse, you will hear that in the first reply, along with whichever part of the family it actually belongs to.

What every family has in common

Four constraints apply equally to a seat fitting and to a carbon disc at an intermediate stage.

ConstraintWhat it means in practice
Drawing authorityGeometry, material, finish, marking and revision state come from your data. A substitute that happens to fit is a design change, not a convenience.
TraceabilityHeat, lot and batch records follow the work to the unit serial. The file has to close on one unit if an auditor pulls it out of a fleet two years later.
Release signatureOutput is released under your approval, by you. We supply the records that support the signature; we do not issue an airworthiness release document.
No catalogueNo part number list, no part number search, no published part count and no stock position. A programme is quoted against a drawing, not browsed.

Send one part number and see what comes back

One number is enough to test us. You will get the process that applies, the tooling position and whether the release path works for your registry.
