AD Compliance Software 2026: Buyer Guide

Aircraft AD compliance software should help an owner, maintenance controller or director of maintenance answer three questions without hunting through disconnected files: which airworthiness directives apply, how each one was complied with, and when any recurring action is due again.

The software does not make the airworthiness decision for you. Under 14 CFR 91.403, the owner or operator is primarily responsible for maintaining the aircraft in an airworthy condition, including compliance with Part 39. The buying decision is therefore less about a polished dashboard and more about configuration accuracy, evidence, review controls and usable exports.

This is a source-based procurement guide, not a hands-on product test, legal opinion or universal ranking. Product scope and contract terms can change. Test any shortlist with a real aircraft and have the resulting compliance status reviewed by the people responsible for that aircraft.

Quick answer: what type of system fits the operation?

Operation	Useful starting point	What must be demonstrated
One light-GA aircraft	A focused record and AD system such as ADLOG, or the AD module in an existing tracker	Aircraft-specific applicability, recurring items, annual update process and a complete export
Corporate turbine aircraft	An analyst-supported platform such as CAMP or Traxxall	Enrollment controls, OEM program alignment, configuration changes, due-list review and transaction-ready records
Part 91 or Part 135 fleet	A fleet platform such as Veryon, CAMP or Traxxall	Multi-aircraft status, permissions, utilization feeds, recurring calculations, work-order handoff and audit reporting
Repair station or in-house shop	A system that connects compliance items to work orders and maintenance entries	Separation between customer aircraft, current data access, sign-off controls and return-to-service records
Paper-logbook backlog	A records-digitisation project alongside the tracking system	Source-document indexing, migration reconciliation, exception handling and export ownership

Those are shortlist categories, not endorsements. A small system kept current can be more defensible than an enterprise platform whose aircraft baseline is wrong.

The record the system has to support

The current-status requirement is more specific than a green compliance badge. 14 CFR 91.417 requires the current status of applicable ADs, including the method of compliance, AD number and revision date. If an AD requires recurring action, the record must include the time and date when the next action is required.

The underlying maintenance entry matters as well. 14 CFR 43.9 specifies the description or acceptable-data reference, completion date and approval details required for maintenance record entries. The FAA's active AC 39-7D provides owner and operator guidance on AD compliance and recording, while the FAA's Airworthiness Directives page identifies ADs as legally enforceable rules issued under Part 39.

A useful system therefore needs to preserve more than the conclusion. It should let a reviewer trace the result back to the aircraft configuration, directive, method of compliance, maintenance entry and next action.

Eight capabilities to test

1. Aircraft and component configuration

AD applicability can turn on model, serial number, installed engine, propeller, appliance, part number, modification or STC. Ask how the platform builds the baseline, who checks it, and what happens when a component is changed.

A system that cannot represent the installed configuration cannot reliably screen effectivity.

2. Directive intake and revision control

Ask where new and revised AD data comes from, how often it is updated, and whether the original directive remains available to the reviewer. A summary can help triage work, but it should not hide the controlling text or incorporated material.

The platform should also distinguish an AD from a service bulletin. A service bulletin may be incorporated into an AD, but the labels are not interchangeable.

3. Applicability review

The software should show pending, applicable, not applicable and further-review states rather than forcing every item directly into compliant or non-compliant. It should preserve the person, date and rationale behind an applicability decision.

CAMP's AD/SB Manager, for example, publishes review, effectivity assessment, application and reporting workflows. The important procurement question is not whether a vendor says it tracks ADs; it is whether your team can see and control the decision path.

4. Recurring calculations

A recurring requirement may use calendar time, hours, cycles, landings or a condition specified in the directive. The demo should show the last compliance event, the interval, the utilization input and the calculated next due point.

Then change the utilization or compliance event and watch the due date recalculate. This is where an attractive due list becomes an operational control or an operational liability.

5. Evidence and maintenance-entry linkage

The current-status line should link to the evidence supporting it: logbook entry, work order, inspection result, parts record, release document or other relevant record. A buyer, inspector or maintenance controller should be able to move from status to source without a separate search through shared drives.

6. Workflows, permissions and review gates

Define who can propose an applicability decision, who can approve it, who can close a compliance item and who can change the aircraft baseline. The system should retain an audit trail rather than silently overwriting history.

For fleets and shops, also test customer separation, base or department views, mobile access, offline limitations and the handoff between a due item, a work order and a completed maintenance entry.

7. Reporting and export

Ask for a complete AD status report, not a screenshot. It should include the aircraft identity, applicable directives, revision data, method of compliance, recurring next action, approval details and useful links to evidence.

Also request a full data export before signing. The operation should understand what can be exported, in which format, how attachments are handled and what happens to access after termination.

8. Enrollment and continuing data quality

The initial migration is part of the product. Ask who reconciles old records, how exceptions are logged, what the acceptance criteria are and how the operation signs off the opening baseline.

Then ask how completed work gets back into the tracker. Traxxall's current terms state that real-time tracking depends on aircraft records or data supplied by the customer and that the customer remains responsible for compliance. That boundary applies more broadly: software can support the control, but it cannot repair missing inputs by itself.

How the main product types differ

CAMP

CAMP MTX publishes due-list, work-order, maintenance-program, AD/SB and analyst-supported workflows aimed primarily at business aviation. Its AD/SB Manager lets operators review staged items, assess effectivity, apply decisions and generate reports.

That is relevant for complex aircraft and fleets where program data and continuing review carry more weight than a low-friction owner interface. During a demo, focus on enrollment responsibility, analyst interaction, configuration changes and export rights.

Veryon

Veryon Tracking is positioned as an aircraft maintenance tracking system spanning real-time records, due items, inventory and connected operational workflows. That broader scope can suit an operator that wants maintenance status to move between the office, shop and aircraft without repeated entry.

Confirm which modules are in the quote, how historical data is checked, how AD applicability is handled, and which actions still sit outside the platform.

Traxxall

Traxxall's maintenance tracking product is aimed at business jets and helicopters, with configurable views, forecasting, inventory connections and analyst support. Its published terms are unusually useful in a buying review because they describe the customer's continuing data and compliance responsibilities.

Ask the vendor to show how those responsibilities appear in the operating workflow: input validation, overdue records, unreviewed changes and escalation.

ADLOG

ADLOG takes a narrower light-aircraft approach. Its published system organises airframe, engine, propeller and avionics records, separates permanently complied-with ADs from those requiring further action, and supplies aircraft-specific AD searches and revision updates.

For a single aircraft, that narrower scope may be appropriate if the owner and maintainer will keep it current. It is not the same job as a fleet maintenance or MRO platform.

The real-aircraft demo

Do not accept a generic demo aircraft with perfect data. Supply one real tail number and a controlled record pack, then ask the vendor to show this chain:

1. Build the airframe, engine, propeller, appliance and modification configuration.
2. Identify potentially applicable ADs and expose the original directive.
3. Record an applicable, not-applicable and further-review decision with rationale.
4. Enter a recurring compliance event and calculate the next due point.
5. Attach the maintenance entry and supporting documents.
6. Change a component and show which applicability decisions reopen.
7. Advance hours or cycles and show the due-list response.
8. Export the complete AD status and supporting data.

Have the person responsible for maintenance control and the person who will enter records both attend. A system can pass the compliance demo and still fail the daily-workflow test.

Contract questions that matter

Before buying, get written answers on aircraft enrollment, implementation milestones, data acceptance, support hours, user roles, storage, security controls, backups, outage procedures, data export, termination assistance and charges for additional aircraft or modules.

Avoid comparing only the recurring subscription. A weak migration, manual double-entry or restricted export can cost more than the software licence. Conversely, a broad suite can be wasteful if the operation needs only a disciplined AD and record system.

Bottom line

The best AD compliance system is the one that makes the responsible people faster at finding, reviewing and proving the correct answer without hiding their accountability.

Start with the aircraft and workflow, not the vendor list. If the platform cannot reproduce a defensible status for a real aircraft, show the source evidence, recalculate recurring actions and export the record, it is not ready to become part of your airworthiness control system.
