Seven days on the due list.
The owner flies out Thursday morning and comes home Monday. The DOM opens the due list and narrows it to the next seven days.
One line is near due: the altimeter, static system and transponder checks, due October 31. There is also one open squawk the crew wrote up Friday: the 2R reading light is out.
Monday, October 26, 07:44
Check the last one.
The line opens the signed entry it was built from, and the page that entry was read from. The last checks were done in October 2024. Twenty-four calendar months runs to the end of October this year.
Due mid-tripMonday, October 26, 07:50
The trip crosses the date.
The airplane leaves Thursday and is due home Monday, November 2. The checks run out on Saturday. After that the airplane cannot fly IFR in controlled airspace until they are done again.
Left alone, the owner is stuck on the West Coast. The work has to happen before Thursday.

Look further ahead.
The DOM widens the range to 90 days. The fire extinguisher weight check comes due in December. The airplane will be down anyway, so it goes in this package.
Doing it early costs nothing on the due list. The next due moves from the day the work is signed.
Monday, October 26, 08:20
Package the downtime.
The DOM groups the three items into a work plan for the avionics shop on the field, with a downtime window of Tuesday 08:00 to Wednesday 17:00. The reading light goes to the in-house tech.
Tuesday, October 27, 16:20
The cards come back signed.
The in-house tech replaces the lamp and weighs the bottle. The tech records the work on each card and the inspector signs. The avionics shop finishes its checks and its signature goes on the card for the vendor.
The shop still owes its test report. Radar keeps that on the card until it arrives.
Release heldWednesday, October 28, 09:10
The release check finds two holds.
Before the airplane goes back into service, the DOM runs the release check. It holds the release and names the card each problem is on.
Wednesday, October 28, 11:30
Clear the holds and release.
The shop's test report arrives as a PDF and goes on the card. The DOM resolves the squawk against the card that fixed it. The check runs clean.
The DOM signs the release with name, certificate number and the release statement.

The signed work becomes the logbook entry.
Radar writes the logbook entries from the signed cards, one for each shop that did the work. Nobody types the work up a second time for the logbook or a third time for the tracker.
Wednesday, October 28, 11:46
The due list resets.
The checks now run to October 31, 2028. The extinguisher check moves to a year from Tuesday. No squawks are open.
Thursday, October 29, 06:15
Wheels up.
The owner leaves on time and comes home legal. The DOM spent the week on the airplane and very little of it in the binders.
