User/Installer Responsibilities

It is important to understand that the existence of this document alone does not automatically constitute authority to install the aircraft engine/propeller/article. Where the user/installer performs work in accordance with the national regulations of an airworthiness authority different than the airworthiness authority of the country specified in Block 1, it is essential that the user/installer ensures that his/her airworthiness authority accepts aircraft engine(s)/propeller(s)/article(s) from the airworthiness authority of the country specified in Block 1. Statements in Blocks 13a and 14a do not constitute installation certification. In all cases, aircraft maintenance records must contain an installation certification issued in accordance with the national regulations by the user/installer before the aircraft may be flown.

What Radar does

Maintenance Tracking runs the work. Records keeps the proof.

01 Maintenance Tracking

Know what's due.

Your due list, squawks, work plans and sign-offs in one place, with a check before every release.

Due list from your maintenance programs, or import your Traxxall status report
Squawks with MEL deferral
Technician and inspector sign each task once
Release to service holds on anything unsigned or missing

How Maintenance Tracking works

02 Records your digital logbook

Prove what's done.

Every logbook page read back to birth, searchable, with the signed page behind every entry.

How Records works

$2,400 to $4,800 per aircraft a year, by aircraft size

+ Maintenance Tracking and Records

Better together.

Run both and the due list and the logbooks stay tied together, line by line.

$6,000 to $13,500 per aircraft a year for both, by aircraft size

Every line opens its page.Each item on the due list links to the signed logbook entry that shows it was done.
Set up from the books.Radar suggests each item's last compliance from your logbooks, so you confirm it instead of typing it.
Sign once, logged once.A signed task writes the logbook entry in Records and moves the due list.
Answers with proof.Ask about any inspection or AD and get the page that proves it.

01 · Maintenance Tracking

Know what's due.

Your due list from your maintenance programs, or import your Traxxall status report. Squawks, work plans and sign-offs in one place, and a check before the aircraft goes back into service.

Due list

A grounding brake wear pin squawk that cannot be deferred, and a fire extinguisher weight check 15 days over

A cabin PA squawk awaiting deferral, a crew oxygen cylinder test due in 11 days, and two more near-due items

The same thing in Radar today, with sample aircraft

Work plan WP-2, a 400 hour inspection: four tasks signed off, a borescope recorded and waiting on the inspector, and a failed brake inspection — **The work plan.** Each task with its result and who signed it.

Release review for work plan WP-2 held on 4 blockers: two tasks recorded but not signed and two with required evidence missing — **The release review.** Stopped by four named items: two unsigned, two with a document missing.

Keep your current tracker while you try it.

Import your Traxxall status report into Radar's maintenance tracking and run both side by side until you're ready to switch. Add the digital logbook and each line opens its page.
