A Transportstyrelsen audit can feel like a courthouse examination. But operators who prepare systematically pass with flying colors. Those caught unprepared face penalties, operational suspension, or mandatory retraining. This guide walks you through what auditors examine, how to prepare your documentation, and the common findings that trigger follow-up actions.
When Do Audits Happen?
๐ฃ
Piyo ๐ฃ (Beginner Pilot)
Piyo: "We got a call from Transportstyrelsen saying they want to audit our operations. We have six weeks' notice. Is that typical?" Poppo: "Exactly typical. Transportstyrelsen announces audits in advanceโusually 4โ8 weeks. This gives you time to organize everything they'll review."
- Initial audit: 2โ4 months after DOM approval (first-time operators)
- Periodic audits: Every 2โ3 years for established operators
- Pre-notification: Usually 6โ8 weeks advance notice
- After an incident or accident
- Following safety complaint from third party
- If insurance claims exceed normal thresholds
- Random audit selection (annual rotation)
- Pre-notification: 2โ4 weeks, sometimes less
- After regulatory changes (new EASA rules)
- If previous audit found deficiencies
- Pre-notification: Usually 4โ6 weeks

Common Audit Findings & How to Avoid Them
Finding 1: Incomplete Flight Logs- Issue: Missing pilot signature, no weather data, vague descriptions
- How to avoid: Use structured flight log form; require digital timestamps; pilot signature mandatory
- Frequency: ~25% of first-time audits
- Issue: Battery age not tracked, motor hours unknown, no calibration dates for sensors
- How to avoid: Implement component-level tracking; calendar reminders for calibration; digital logbook
- Frequency: ~30% of audits
- Issue: No recurrent training in 12+ months, flight hours not documented, competency gaps
- How to avoid: Annual training requirement, tracked hours per pilot, pre-audit currency check
- Frequency: ~15% of audits
- Issue: DOM doesn't reflect actual operations, procedures not updated
- How to avoid: Annual DOM review, update when operations change, version control with dates
- Frequency: ~20% of audits
- Issue: Operations conducted without documented risk assessment or mitigation strategy
- How to avoid: Risk assessment before every new operation type, templates, documented approval
- Frequency: ~18% of audits
- Issue: Policy expired, coverage limits mismatched to operations, provider not Transportstyrelsen-approved
- How to avoid: Calendar reminder 60 days before expiration, coverage review annually, verified provider list
- Frequency: ~10% of audits
- Issue: Incident occurred but wasn't reported to Transportstyrelsen within required timeframe
- How to avoid: Incident reporting procedure manual, clear definition of reportable events, immediate notification protocol
- Frequency: ~5% of audits (but very serious)

- Verify all pilot certificates current with Transportstyrelsen
- Confirm insurance policy is active and covers all aircraft
- Update flight logs and maintenance records to current date
- Organize all documents by category in audit folder
- Create document index (quick reference for auditors)
- Brief all staff on audit procedures and expectations
- Conduct mock interview with audit coordinator asking sample questions
- Final documentation review
- Confirm auditor contact details and meeting location
- Arrange facilities (conference room with table, adequate lighting)
- Brief pilots on interview etiquette (honest, direct answers; no evasion)
- Auditors typically start 8:30 AM
- Allow 4โ8 hours depending on operation scale
- Have responsible manager and safety officer present
- Provide coffee and workspace access
- Answer questions directly and honestly
- Transportstyrelsen delivers written findings within 2 weeks
- Minor non-conformances allow 30-day corrective action period
- Serious findings may require immediate action plan
- Re-audit scheduled if significant gaps found

Q: What if I find gaps in my documentation before the audit?A: Report them proactively. Transportstyrelsen appreciates operators who identify and correct issues before inspection. It demonstrates professionalism and doesn't result in automatic penalties.
Q: How long are audit findings valid before I must respond?A: Minor findings: 30 days. Major findings: Immediate action plan due within 7 days. Re-audit may be scheduled depending on severity.
Q: What happens if I fail the audit?A: Audit failure results in a corrective action notice. You have 30โ60 days to address findings. Failure to remedy results in operational suspension until compliance is demonstrated.
Q: Can I bring a consultant or lawyer to the audit?
