Components
The maintenance building blocks of an aircraft — engines, propellers and the like — each with its own maintenance checks.
What it is
Components are the parts that make up an aircraft and that maintenance checks are tied to — airframe, engine, propeller, parachute and similar parts. A component definition has its own maintenance checks; each check is made up of one or more parts based on flight hours, number of launches, a fixed date, or the number of days since the last maintenance.
Every definition has a scope that determines which aircraft it applies to: the whole fleet, a single category, a single type, or one specific aircraft. A component can track counters (operating hours, launches) or none — if its checks are purely calendar-based. The airframe is a system, fleet-wide component that tracks both hours and launches and is protected from being renamed or deleted.
Component checks generate airworthiness alerts on the Dashboard.

How to use it
- Browse components — the list at
/aircraft-componentsshows definitions grouped by scope (whole fleet, category, type, specific aircraft) and is searchable. - Component definition — a new definition is created at
/aircraft-components/definitions/new— you enter a name, counters (operating hours / launches) and a scope. - Configure checks — a check is added to a component at
/aircraft-components/checks/new(or via the “Add check” button on the component); it is made up of parts based on hours, launches, a date or a number of days, and can target selected aircraft types. - Link to the Dashboard — these checks generate maintenance alerts on the Dashboard.
