Continuing airworthiness engineers maintaining an AD compliance register in a spreadsheet that requires manual recalculation of due dates every time a new flight hours figure or flight cycle count is received?
An upcoming CAMO audit requiring weeks of preparation to compile the compliance evidence that should be available from the airworthiness management system at any point in time?
Airworthiness Compliance Software Development
Airworthiness directive compliance management is a regulatory obligation that carries direct safety and legal consequences if it fails. 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 -- your aircraft types, your engine and component configurations, your compliance methods, and the audit documentation your regulatory authority expects.
AD applicability determination for each aircraft registration based on its type, serial number, engine type, and installed equipment, with the applicability logic documented and auditable
Compliance method recording capturing the approved means of compliance, the source document, and the evidence that compliance has been achieved for each applicable AD
Due date calculation for repetitive ADs based on current flight hours, flight cycles, and calendar time, with automatic recalculation when utilisation data is updated
Alert generation for ADs approaching their compliance due date, with lead time configured by AD category and severity
RaftLabs builds custom airworthiness compliance software for continuing airworthiness management organisations that need AD applicability determination, compliance method recording, due date calculation, alert generation, and CAMO audit support in one connected system. Most projects deliver in 12 to 18 weeks at a fixed, agreed cost.

When continuing airworthiness management 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 is managing a fleet with characteristics that sit outside the platform's assumptions -- multiple aircraft types from different registries, older aircraft where the type certificate data sheet configuration differs from the current baseline, or engines and components where the 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 applicability determination logic reflects the specific aircraft, engine, propeller, and component combinations in your fleet. The compliance method recording captures the evidence your authority expects to see. The due date calculation handles the specific units of compliance -- hours, cycles, months, or landings -- for each AD type. And the audit preparation workflow assembles the compliance evidence from the system records rather than requiring your engineers to compile it manually.
What we build
AD applicability determination
Applicability analysis for each aircraft registration based on its type certificate, serial number, engine type, engine serial number range, propeller type, and installed avionics and equipment, matching each parameter against the effectivity statement of each current and historic AD. Applicability determination records documenting the reason each AD is applicable or not applicable to each aircraft, so the CAMO engineer's reasoning is captured in the system and available for audit rather than existing only in the engineer's head. Configuration tracking for installed modifications that affect AD applicability -- STCs that terminate an AD requirement, or modifications that introduce new AD applicability -- linked to the relevant modification record. Regulatory database integration pulling new AD publications from the relevant authority's feed -- FAA, EASA, CASA, CAA -- and applying the applicability determination logic automatically to flag newly applicable ADs for engineer review. Fleet-level applicability summary showing which ADs apply across the fleet, how many aircraft are affected by each AD, and the current compliance status across the fleet.
Compliance method recording
Compliance record for each applicable AD capturing the approved means of compliance used -- accomplishment of the AD in accordance with the instructions, or an alternative means of compliance approved by the authority -- with the source document reference, revision, and date. Alternative means of compliance management where the operator or CAMO has obtained an AMOC from the authority, linking the AMOC approval document to the compliance record and tracking the AMOC's specific compliance requirements separately from the original AD. Compliance evidence storage linking the maintenance work order, task card completion record, or inspection report that provides the evidence of compliance directly to the AD compliance record, so the evidence is retrievable from the compliance record without a separate search. Compliance history showing every compliance event for a repetitive AD -- each interval's accomplishment date, flight hours, flight cycles, and the certifying engineer or inspector who signed off the task. One-time AD compliance recording with the accomplished date, the aircraft's hours and cycles at accomplishment, and the document reference, retained in the system for the life of the aircraft.
Due date calculation and tracking
Due date calculation for repetitive ADs based on the compliance interval defined in the AD -- hours since last accomplishment, cycles since last accomplishment, calendar time since last accomplishment, or a combination -- with the current due date recalculated automatically when updated utilisation data is received. Multi-threshold tracking for ADs with both a warning threshold and a mandatory compliance date, displaying both thresholds in the compliance status view so engineers can plan the maintenance visit before the warning threshold rather than the mandatory date. Flight hours and cycles update from the aircraft's technical log or the operator's utilisation reporting system, with each update triggering recalculation of all repetitive AD due dates for the affected aircraft. Due date report for each aircraft showing every applicable repetitive AD, its current compliance status, and its calculated due date -- the basis for maintenance planning and scheduling of the next check. First-time compliance due date calculation for new ADs with a compliance grace period expressed as hours or cycles from a specific date, calculating the latest compliance date for each aircraft based on its current utilisation.
Alert generation and escalation
Alert configuration for each AD category -- mandatory, alert, and routine -- with the lead time for each alert category set by the CAMO's quality manager and applied consistently across all applicable ADs. Pre-due alerts sent to the continuing airworthiness engineer responsible for the aircraft at the configured lead time before the due date, with the current utilisation, the calculated due date, and the remaining hours or cycles clearly stated in the alert. Overdue alert escalation when a repetitive AD passes its due date without a compliance record being entered, escalating to the CAMO quality manager and the aircraft owner with the number of days or hours overdue. Alert suppression for ADs where a maintenance visit has been scheduled and confirmed, replacing the pre-due alert with a confirmation that the AD will be accomplished in the upcoming check. Daily airworthiness status report distributed to the CAMO engineering team and the aircraft owner showing all ADs due within the next 30, 60, and 90 days for each aircraft in the fleet.
Continued airworthiness documentation
Continued airworthiness records for each aircraft compiling the AD compliance history, component life records, modification records, and maintenance records into a single retrievable set -- the basis for the aircraft's continuing airworthiness management and its sale documentation. Component time and cycle tracking for life-limited components and on-condition components subject to AD compliance requirements, linked to the aircraft's flight log data so component hours and cycles are updated automatically with each flight. Modification record management tracking STCs, major repairs, and modifications approved under alternative procedures, with each modification's effect on the AD compliance baseline documented. Aircraft technical log integration pulling flight hours, cycles, and landings from the operator's technical log system to update the continuing airworthiness records without manual re-entry. Document retention management ensuring that continuing airworthiness records are retained for the regulatory minimum period and flagging records approaching the end of their mandatory retention period.
CAMO audit support
Audit preparation workflow generating the compliance evidence package for a regulatory audit from the system records -- the AD compliance register, the compliance evidence for each applicable AD, the component life records, and the modification records -- compiled automatically rather than assembled manually by the engineering team. Finding management recording audit findings, their grading, the corrective action required, and the response deadline, with escalation to the quality manager when corrective actions are approaching their due date without being closed. Compliance gap identification running a pre-audit check across the compliance register to identify any applicable ADs with missing compliance records, missing evidence, or expired compliance dates before the auditor reviews the same records. Historical compliance record reconstruction for cases where the aircraft's compliance history predates the system, providing a structured import workflow to capture historic compliance events with their dates, hours, and cycles. Audit trail of every change to the compliance register -- who added or amended a compliance record, when, and what they changed -- satisfying the regulatory requirement for an auditable airworthiness management system.
Frequently asked questions
Yes. The system supports multiple regulatory authority feeds -- FAA, EASA, CASA, CAA, and others -- and the AD applicability determination is 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 the 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. Where an AD applies to a specific serial number range, the system evaluates each aircraft's configuration record against the effectivity statement and records the determination with the reasoning. Configuration changes that affect applicability -- an engine change or modification -- trigger a re-evaluation of all AD applicability for the affected aircraft.
Yes. The continued airworthiness records for each aircraft -- AD compliance history, component life records, and modification records -- can be exported as a structured data package and a PDF summary document for disclosure to a prospective purchaser or a receiving authority on aircraft import. The system retains the complete compliance history for the life of the aircraft regardless of CAMO changes.
A focused build covering AD applicability determination, compliance recording, due date calculation, and alert generation typically runs $50,000 to $100,000 depending on fleet size and the number of regulatory authority integrations. Adding CAMO audit support, continued airworthiness documentation, and multi-registry coverage brings the total to $100,000 to $180,000. Fixed cost agreed before development starts, no hourly billing.
