A squawk on a clipboard is a squawk dispatch never sees
In most small operations, maintenance status lives in three places: the binder in the aircraft, the whiteboard in the shop, and the mechanic's memory. The schedule lives somewhere else entirely. The Maintenance Hub puts fleet status, open squawks, inspection countdowns, and work orders in one place, and feeds the result straight to the schedule, so an aircraft with a grounding item cannot be dispatched by accident.
Every aircraft shows its hours to the next 100-hour inspection, its annual due month, and its oil change interval. When a pilot writes up a squawk, the shop sees it the same day it is reported, with the severity called the way a mechanic would call it: grounding, or deferred and placarded inoperative.

The whole fleet on one board
Status, inspection countdowns, oil tracking, and open squawk counts for every aircraft, with the active squawk list and the queued maintenance work alongside. A chief instructor or shop lead can read the state of the fleet in one pass, before the first flight of the day.

Shop time recorded as it happens
Each work order names the aircraft, the discrepancy, the assigned mechanic, and every time entry against it. The demonstration below is interactive: clock in, then clock out, and watch the entry land on the work order with the total updated. No more reconstructing shop hours from memory at invoicing time.
Right magneto: remove, bench inspect, replace contact points and condenser, reinstall, time to engine, and verify runup within limits.

Squawks reach the right people
A pilot reports a squawk from the aircraft page, the shop sees it on the hangar dashboard, and dispatch sees the result on the schedule. Grounding items restrict the aircraft immediately; deferred items stay visible until they are cleared.
Work orders carry their own time
Each work order tracks who worked it, when they clocked in and out, and the running total. Shop time stops being a reconstruction at the end of the month and becomes a record kept as the work happens.
Inspections never sneak up
Hours to the next 100-hour, the annual due month, and the oil change interval are counted down per aircraft as the fleet flies. The schedule restriction follows automatically when an item comes due.
Serialized parts, counted before they run out
Filters, plugs, tires, and serialized components tracked with quantity on hand against a reorder point. A part that drops to its reorder point is flagged before it is the reason an aircraft sits, and serial numbers stay attached from the shelf to the airframe.
| Part number | Description | Serial / lot | On hand | Reorder point | Stock status |
|---|---|---|---|---|---|
| CH48110-1 | Oil filter, spin-on | Lot 26-0387 | 12 | 6 | Adequate |
| SL4371 | Magneto, left, O-320 | 07050233 | 1 | 2 | Low stock |
| REM40E | Spark plug, massive electrode | Lot 26-0512 | 8 | 12 | Low stock |
| 606C66B8 | Tire, 6.00-6, 6 ply, main gear | T2608443 | 3 | 2 | Adequate |
| RA66-106 | Brake lining, Cleveland | Lot 26-0298 | 10 | 8 | Adequate |
| AA3216CW | Vacuum pump, dry air | V0982236 | 0 | 1 | Low stock |
Rows at or below the reorder point are flagged so consumables are ordered before they hold a work order open. Serialized components keep their serial numbers with them from the shelf to the airframe.
Logbook entries generated in the customary format
When a work order closes, the hub generates the logbook entry text: the description of work performed, the date, the tach time, and a signature line with the mechanic's certificate number, formatted for the airframe, engine, or propeller record. Try it below; the preview updates as you type.
Drained engine oil and replaced with 7 quarts Phillips 20W-50. Removed oil filter, installed new filter P/N CH48110-1, torqued and safetied. Cut and inspected old filter element, no metal found. Ground run performed, no leaks noted.
The generated text supports the official maintenance record. The signed entry in the aircraft records, made by the person performing the work, remains the record of authority.
The Maintenance Hub organizes squawks, work orders, and inspection reminders. It does not take over the aircraft's legal records. Under 14 CFR §91.403 the registered owner or operator remains primarily responsible for maintaining the aircraft in an airworthy condition, and under 14 CFR §91.417 the owner or operator keeps the required maintenance records. Entries generated here support those official records. They do not replace them.
Maintenance status reaches the schedule on its own
When an inspection comes due or a grounding squawk is logged, the aircraft's row on the schedule is marked and flight reservations against it are restricted automatically. The shop does not have to call the front desk, and the front desk does not have to remember.
| Aircraft | 08:00 | 09:00 | 10:00 | 11:00 | 12:00 | 13:00 |
