Airworthiness Compliance Software Development
Airworthiness compliance software built around your fleet's actual configuration, not a commercial CAMO template.
Commercial continuing airworthiness management systems handle the standard AD tracking workflow, but CAMOs managing specialist fleets, legacy aircraft, or mixed-registry aircraft often find that standard systems cannot model their compliance methods, their AD applicability determinations, or their audit evidence requirements without significant manual workarounds. We build airworthiness compliance systems designed around your fleet and your CAMO approval.

The brief
Start with what is not working.
Good software decisions begin with the constraint, not a list of features or a preferred technology.
Continuing airworthiness engineers maintaining an AD compliance register in a spreadsheet that requires manual recalculation every time new flight hours are received?
An upcoming CAMO audit requiring weeks of preparation to compile evidence that should be available at any point in time?
Plain answer
RaftLabs builds custom airworthiness compliance software for CAMOs managing specialist, legacy, or mixed-registry fleets. It handles AD applicability by aircraft serial number, compliance method recording with audit-evidence links, automatic due-date recalculation on new utilisation data, and CAMO audit-pack generation from live records. Scope and fixed cost are agreed in writing before development starts.
What to remember
- Standard CAMO platforms (CAMP Systems, AMOS, Flightdocs) serve large commercial operators well but break down for mixed-registry or legacy fleets with non-standard AD applicability logic.
- AD applicability is determined per aircraft against serial number, engine, propeller, and equipment configuration, with the reasoning captured for audit rather than left in an engineer's head.
- Due dates recalculate automatically on every new hours/cycles update, so the register stays current between maintenance visits.
The AD register that stopped living in a spreadsheet.
Every time new flight hours arrive, a continuing airworthiness engineer opens the spreadsheet and recalculates the repetitive AD due dates by hand. Between visits, the register drifts out of date, and the reasoning behind each applicability call sits in one engineer's head.
Then a CAMO audit lands on the calendar. Weeks disappear into assembling evidence that should have been retrievable at any point in time.
The spreadsheet was not the problem. The problem is that the compliance record should recalculate itself and produce its own audit pack.
When commercial CAMO systems fall short for your fleet
CAMP Systems, Swiss Aviation Software AMOS, and Flightdocs serve large commercial operators well. The limitation appears when a CAMO manages a fleet with characteristics outside the platform's assumptions. That means multiple aircraft types from different registries, older aircraft where the type certificate configuration differs from the current baseline, or engines and components where AD applicability is determined by manufacturer serial number range rather than aircraft type alone.
Custom airworthiness compliance software is built around your fleet's actual configuration, the specific aircraft, engine, propeller, and component combinations you operate, with compliance method recording, due date calculation, and audit preparation matched to your CAMO's evidence requirements.
We have built compliance-critical, audit-facing software since 2015, in regulated domains where records have to survive an auditor's scrutiny. Airworthiness is a specialist regime, and we will be straight about it. Our depth is in building configurable compliance and audit-evidence systems. We scope every aviation engagement with your continuing-airworthiness engineers, so the applicability logic reflects your fleet, not our assumptions. The team that scopes your fleet is the team that builds the system. No bait-and-switch, no offshore handoff after the contract is signed. We scope the work, calculate the cost, and lock it in writing before development starts. Custom software is justified by mixed-registry, legacy-fleet, or non-standard applicability needs, not recommended by default. We will tell you when a commercial CAMO platform is enough.
Custom pays off when your fleet breaks the standard applicability model.
Everything on the left should already be true for your CAMO. Even one thing on the right, and a commercial CAMO platform is the smarter first step.
A mixed-registry, legacy, or specialist fleet where AD applicability turns on serial number range, not aircraft type alone.
An AD compliance register living in a spreadsheet that needs manual recalculation every time new hours or cycles arrive.
A CAMO audit that means weeks of assembling evidence which should be retrievable at any moment.
A standard single-type, single-registry fleet that CAMP Systems, AMOS, or Flightdocs already handles well.
AD applicability that follows aircraft type alone, with no serial-number or configuration exceptions.
You want an off-the-shelf platform to configure, not software built around your fleet.
What we build
What airworthiness compliance software covers
AD applicability determination
Applicability analysis for each registration against type certificate, serial number, engine, propeller, and installed equipment, matched to each AD's effectivity statement. Applicability determinations are recorded with the engineer's reasoning, and configuration changes (an engine change, an STC) trigger automatic re-evaluation.
Compliance method recording
Each applicable AD's compliance record captures the approved means of compliance, the source document, and any alternative means of compliance approved by the authority. Evidence, the maintenance work order or inspection report, links directly to the compliance record for audit retrieval.
Due date calculation and tracking
Repetitive AD due dates recalculate automatically on hours, cycles, or calendar time as new utilisation data arrives. Multi-threshold tracking (warning plus mandatory date) lets engineers plan a maintenance visit ahead of the deadline rather than reacting to it.
Alert generation and escalation
Configurable lead times by AD category (mandatory, alert, routine) trigger pre-due alerts to the responsible engineer, with overdue escalation to the quality manager and aircraft owner. A daily fleet status report shows every AD due in the next 30, 60, and 90 days.
Continued airworthiness documentation
Continued airworthiness records compile AD history, component life records, and modification records per aircraft into a single retrievable set, the basis for sale documentation. Component time and cycle tracking updates automatically from flight log data.
CAMO audit support
Audit preparation compiles the compliance evidence package automatically from system records rather than by manual assembly. A pre-audit gap check flags applicable ADs with missing evidence or expired compliance dates before the auditor finds them.
The regulatory regimes we design around
Aerospace and defense compliance is not one framework. A system that only tracks ADs misses the regimes that surround airworthiness. We design the data model, access controls, and audit trail so the same records answer to whichever of these apply to your operation.
- FAA / EASA airworthiness
- Continuing airworthiness under FAA 14 CFR Part 39 (Airworthiness Directives) and EASA Part-M / Part-CAMO. Demands AD applicability per aircraft, recorded means of compliance, and continuous audit-ready records for the life of the aircraft.
- AS9100
- The aerospace quality management standard (built on ISO 9001) for design and manufacturing suppliers. Demands configuration management, traceability, nonconformance handling, and objective evidence a registrar can audit.
- ITAR / EAR export control
- Defense and dual-use articles and technical data fall under State (ITAR) and Commerce (EAR) jurisdiction. Demands access control, data residency, nationality-based authorisation, and a defensible record of who touched controlled technical data.
- DO-178C / DO-254
- Airborne software (DO-178C) and complex airborne electronic hardware (DO-254) assurance for certification. Demands requirements traceability, verification evidence, and configuration control at the design-assurance level assigned to the function.
- NADCAP
- Accreditation for special processes (heat treat, welding, non-destructive testing, chemical processing). Demands controlled process records, operator certification tracking, and audit evidence tied to each accredited process.
We are not a certification authority, and we do not sell an approval. We build the software system that makes the evidence for these regimes retrievable on demand instead of assembled under audit pressure.
Pitfalls we plan around
Airworthiness compliance systems fail in predictable ways. We design against the failure modes continuing-airworthiness engineers already know.
Where airworthiness records are heading
The regulators and OEMs are moving toward a digital thread: a continuous, machine-readable record that links a part's configuration, its compliance history, and its maintenance evidence from design through retirement. Model-based systems engineering (MBSE) is pushing the same shift on the design side, where requirements, verification, and configuration live as connected data rather than documents. A compliance system built on structured, exportable records rather than PDFs and spreadsheets is what lets your fleet data plug into that thread later instead of being re-keyed. We build for that destination now, so the records you capture today stay useful as the standard tightens.

Common questions
Yes. The system supports multiple regulatory authority feeds, FAA, EASA, CASA, CAA, and others, with AD applicability determination run separately for each aircraft based on its registry. An aircraft on a foreign registry operating under a bilateral agreement can have its FAA AD compliance requirements tracked alongside locally-mandated requirements in the same system.
The applicability determination logic handles effectivity statements based on aircraft serial number, engine serial number, propeller serial number, and installed equipment. Configuration changes that affect applicability, such as an engine change or modification, trigger a re-evaluation of all AD applicability for the affected aircraft.
Yes. Continued airworthiness records, AD compliance history, component life records, and modification records can be exported as a structured data package and a PDF summary for disclosure to a prospective purchaser or receiving authority on import. The system retains the complete history for the life of the aircraft regardless of CAMO changes.
The strong answer: one governed data model with field-level history and role controls. The weak answer: multiple masters with batch syncs and manual reconciliation. Ditch the spreadsheets and paper silos for centralized software with controlled master data, version control, and role-based approvals. Traceability means an auditor asks for an AD, a repair, or a serial-controlled part and gets evidence in minutes, not days.
The 14 CFR ritual: AD number, effective date, method of compliance, current time-in-service, next due time and date, signature and certificate number of the approver. The failure mode is the missed when-due-next: an over-flown AD grounds the aircraft, and the record has to explain why it slipped. The AD register that stopped living in a spreadsheet: AD applicability determination, compliance method recording, due date calculation and tracking, alert generation and escalation.
The strong answer: time-stamped field changes, attachment lineage, e-signature support. The weak answer: record history existing only at document level. Continued airworthiness documentation must survive an audit: every state change carries versions, attribution, timestamps, reason, approvals, and exports according to client rules. An auditor should be able to ask for any AD and get the full compliance history in minutes.
Run the one-screen test: is my aircraft compliant right now? Logbooks, inspections, ADs, registration in one plain-language readiness picture with color-coded deadline countdowns, not a module list. Check the planning story: does visit planning, slot control, shortages, and rotable demand connect in real time, or does it export to spreadsheets? And ask the multi-registry question: can it manage aircraft on different registries with different AD databases? True cost per flight hour is the honest metric.
Every engagement is scoped against your fleet first, and the price is fixed in writing before development starts. What it comes to depends on fleet size, registry count, and which authority integrations the build needs. The first week of the process produces the fixed-price quote.
