L4 Process Steps
| Step | Step Name | Role / Swim Lane | System | Input | Output | KPI | Dec? | Exc? |
|---|---|---|---|---|---|---|---|---|
Phase 1 1.1 |
Capture work order completion data in MRO system | Aircraft Maintenance Technician (AMT) | AMOS by Swiss AviationSoftware | Completed maintenance task card or work order | Closed work order record with technician stamp, part numbers, and man-hours | Work order closure within 2 hours of task completion; >98% same-shift closure rate | N | N |
| 1.2 | Ingest aircraft technical logbook entries | Aircraft Maintenance Technician (AMT) | AMOS by Swiss AviationSoftware | Aircraft Technical Log (ATL) — paper or Electronic Technical Log (ETL) feed | Digitised logbook entry linked to flight sector and aircraft tail number | 100% of ATL entries ingested before next departure; ETL integration uptime ≥99.5% | N | Y |
| 1.3 | Validate record completeness against work order schema | Records Control Clerk | AMOS by Swiss AviationSoftware | Ingested work order and logbook entry | Completeness check result — pass or list of missing mandatory fields | Record completeness rate ≥99.5%; incomplete records resolved within 4 hours | Y | N |
Phase 2 2.1 |
Cross-reference task against approved AMM/SRM data | Quality Assurance Inspector | Boeing Toolbox (Technical Document Management) | Closed work order with task card reference | Confirmation that executed task matches approved maintenance data revision | Zero maintenance releases citing a superseded AMM revision; 100% AMM revision currency per Boeing Service Letter cycle | N | Y |
| 2.2 | Verify certifying technician licence and authorisation | Quality Assurance Inspector | AMOS by Swiss AviationSoftware | Technician employee ID extracted from work order sign-off | Authorisation check result — licence type, rating, and currency status | Zero maintenance releases by technicians with expired or out-of-scope ratings; authorisation check automated for 100% of closures | Y | Y |
| 2.3 | Confirm maintenance release and CRS sign-off | Certifying Staff / Licensed AME | AMOS by Swiss AviationSoftware | Verified work order, authorisation check pass, logbook entry | Certificate of Release to Service (CRS) or Maintenance Release Statement recorded in AMOS | CRS issued within 30 minutes of final inspection; 100% of CRS statements traceable to FAR Part 43 / EASA Part-145 signatory | N | Y |
Phase 3 3.1 |
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 |
