aircraft, including inspections, parts replaced, and mechanic signoffs.

Logbook entries document *maintenance events* -- they are not per-flight records.

Sub-Tabs
--------

The logbook is organized into sub-tabs that filter entries by log type:

- **All** -- Shows all entries regardless of type.
- **AC** (Airframe) -- Airframe maintenance entries.
- **ENG** (Engine) -- Engine-related maintenance.
- **PROP** (Propeller) -- Propeller maintenance.
- **OTHER** -- Entries that don't fit the above categories.

Searching and Filtering
-----------------------

Use the **search bar** to find entries by text content. You can also filter by
**entry type** using the dropdown:

- Maintenance
- Inspection
- Flight
- Hours Update
- Other

The total entry count updates as you filter.
