Update component life-tracking and next-due dates Technical Records Analyst CAMP Systems (Continuous Airworthiness Monitoring Programme) Closed and certified work order with part removals, installations, and time since new (TSN) data Updated component life record showing revised TSN, cycles since new (CSN), and next maintenance due date Component record updated within 8 hours of part installation; life-limit threshold accuracy ±0 flight hours/cycles N N
3.2 Link AD/SB compliance closure record to aircraft serial Technical Records Analyst CAMP Systems (Continuous Airworthiness Monitoring Programme) AD or Service Bulletin number, effectivity, compliance method, and accomplishment date AD compliance entry linked to tail number and fleet record in CAMP 100% of applicable ADs reflected in CAMP within 24 hours of task closure; zero open ADs past compliance deadline N Y
3.3 Identify overdue or near-threshold compliance items Airworthiness Compliance Manager CAMP Systems (Continuous Airworthiness Monitoring Programme) CAMP automated compliance forecast report run daily Prioritised exception list of ADs, LLP limits, and scheduled tasks within 30-day or 100-FH threshold Zero items entering the overdue state; 100% of near-threshold items actioned ≥7 days before due date Y N
3.4 Escalate critical airworthiness findings to MCC and Planning Airworthiness Compliance Manager AMOS by Swiss AviationSoftware Exception list from CAMP with overdue or critical near-threshold items Work order raised in AMOS; maintenance slot requested from MCC; aircraft grounding risk flagged if threshold cannot be met in-service MCC notified within 2 hours of threshold breach identification; grounding avoided in ≥95% of escalations through proactive slot allocation Y Y
Phase 4
4.1
Archive work orders per FAA retention schedule Records Control Clerk AWS S3 (Long-Term Document Archive) Certified and closed work orders exported from AMOS Immutable PDF/A records stored in versioned S3 bucket with metadata tags (tail, date, task reference) 100% of closed work orders archived within 24 hours; retention period ≥24 months per FAR Part 121.380 for routine tasks, ≥life of aircraft for major repairs N Y
4.2 Generate aircraft technical status summary report Technical Records Analyst Tableau (BI & Reporting) CAMP compliance data, AMOS work order history, AWS S3 archive index Aircraft Technical Status Report (ATSR) per tail: open deferrals, AD status, LLP remaining life, next check due ATSR published weekly for all active tails; zero data discrepancies between ATSR and AMOS/CAMP source systems N N
4.3 Validate archived record format for regulatory compliance Quality Assurance Inspector AWS S3 (Long-Term Document Archive) Archived PDF/A records sampled from S3 for format and metadata audit Validation report confirming PDF/A-1b compliance, metadata completeness, and tamper-evident hash integrity 100% of sampled records pass PDF/A validation; zero records with missing mandatory metadata fields; hash verification failure rate 0% Y Y
Phase 5
5.1
Compile records package for FAA/authority audit Director of Quality Assurance AMOS by Swiss AviationSoftware FAA audit notice specifying scope (tail numbers, date range, AD references) Structured audit evidence package: certified work orders, CRS statements, AD compliance records, technician authorisation records Audit package delivered within 5 business days of FAA request; zero findings of missing required records in formal audit N N
5.2 Respond to AD compliance queries from airworthiness authority Airworthiness Compliance Manager CAMP Systems (Continuous Airworthiness Monitoring Programme) FAA/authority query specifying AD number, effectivity date, and fleet scope Formal compliance response citing accomplishment dates, methods of compliance, and tail-by-tail status exported from CAMP AD compliance query response within 10 business days; 100% of responses supported by primary source documentation traceable to original work order Y Y
5.3 Submit airworthiness certificate renewal documentation Director of Quality Assurance FAA DragonWave / FAA PTRS (Programme Tracking & Reporting Subsystem) Compiled ATSR, AD compliance summary, major repair/alteration records, current maintenance programme approval Airworthiness Certificate renewal package submitted to FAA FSDO; certificate issued or discrepancy list returned Certificate renewal submitted ≥30 days before expiry; zero aircraft operated with lapsed airworthiness certificate; discrepancy resolution within 15 business days N Y

Airline-Specific Risks & Pain Points

Paper-based job cards still used at some line stations — manual re-keying into AMOS introduces transcription errors and delays record closure past the shift boundary
ETL interfaces to PSS (Amadeus Altéa) are non-standardised across fleet sub-types; legacy B737-700 may lack ETL hardware, requiring manual paper log reconciliation
AMOS mandatory-field validation rules vary by maintenance type (line vs. heavy); misconfigured validation profiles cause false-pass records that fail FAA audit spot-checks
Boeing Toolbox AMM revision pushes can lag up to 72 hours behind FAA-approval date; tasks executed on interim revisions may require retroactive re-documentation, increasing rework cost
AMOS authorisation matrix must be kept synchronised with FAA A&P licence renewals and airline-specific OJT records; manual update lag creates windows where expired ratings are not flagged
Dual-registry aircraft (operating under both FAA and EASA authority) require CRS language compliant with both regulations; AMOS templates are not always jurisdiction-aware, requiring manual text override
