Your next FAA certification inspection could be announced tomorrow. When the inspector asks to see 12 months of self-inspection records, training documentation for every airside employee, and corrective action logs for every discrepancy found, will you hand over an organized digital file or start digging through filing cabinets? For 520+ Part 139 certificated airports in the U.S., compliance is not optional. Violations mean daily financial penalties, Letters of Correction, operational restrictions, or certificate revocation. OXmaint automates the documentation trail that keeps you audit-ready every single day. Schedule a demo to see how OXmaint turns compliance from a scramble into a system.
What FAA Part 139 Requires
14 CFR Part 139 governs the certification and operation of U.S. airports serving scheduled air carrier operations with more than 9 passenger seats. The regulation covers everything from runway markings and ARFF equipment to wildlife hazard management and fueling safety. At its core, Part 139 is a documentation regulation. Every requirement demands a record, and every record must be current, accessible, and audit-ready.

The Compliance Areas That Get Airports in Trouble
FAA certification inspections follow a structured process, covering administrative records review, movement area inspections, night inspections, and post-inspection briefings. When discrepancies are found, the FAA issues Letters of Correction with deadlines. Repeat violations escalate to financial penalties assessed per day of non-compliance. These are the documentation areas where airports most commonly fail.
139.327
Self-Inspection Records
Daily self-inspections of movement areas must be documented showing conditions found and all corrective actions taken. Records must be maintained for at least 12 consecutive calendar months. Missing or incomplete inspection logs are the most common audit finding.
139.303
Personnel Training Records
Every individual with airside access must receive initial and recurrent training covering airport familiarization, signs, markings, and lighting. Training records must be maintained for 24 consecutive calendar months. Gaps in training documentation trigger immediate corrective action.
139.319
ARFF Equipment Readiness
Aircraft Rescue and Fire Fighting vehicles must meet response time requirements and extinguishing agent quantities. Maintenance logs, agent level checks, and response time records must be documented and available for inspector review at all times.
139.321
Pavement and Marking Condition
Runway, taxiway, and apron pavements must be maintained to prevent conditions that could cause FOD or impair safe operations. Documentation of pavement condition assessments, marking maintenance, and corrective action timelines is required.
139.325
Airport Emergency Plan
A comprehensive emergency plan covering aircraft incidents, bomb threats, structural fires, natural disasters, and hazmat events must be maintained current. The plan must be reviewed and updated with all participating agencies. Full-scale exercises required every 36 months.
139.337
Wildlife Hazard Management
Wildlife strike data must be collected, reported, and documented. If a wildlife hazard assessment is required, the resulting management plan must be followed and all mitigation actions recorded. Incomplete strike reports are a recurring audit issue.
The FAA can conduct unannounced inspections at any time. OXmaint keeps every inspection record, training log, and corrective action digitally organized and instantly retrievable, so your documentation is always audit-ready.

Frequently Asked Questions
What happens if our airport fails a Part 139 inspection?
The FAA issues a Letter of Correction identifying violations and discrepancies with deadlines for corrective action. If violations are not corrected, the FAA can impose financial penalties for each day of continued non-compliance. In extreme cases, the FAA may revoke the Airport Operating Certificate or restrict areas where air carriers can operate. OXmaint's corrective action tracking ensures every finding is documented, assigned, and resolved before deadlines, with closure verification that satisfies follow-up inspections.
How long must Part 139 records be retained?
Self-inspection records must be maintained for at least 12 consecutive calendar months. Training records must be retained for 24 consecutive calendar months after completion of training. OXmaint automatically enforces these retention periods, archiving records with full timestamps and preventing premature deletion. Records beyond the minimum retention period remain searchable for trend analysis and historical reference.
Book a demo to see the retention management system.
Can OXmaint handle the new SMS requirements under Part 139 Subpart E?
Yes. The February 2023 amendment to Part 139 added Safety Management System requirements for certain certificated airports. OXmaint integrates SMS hazard identification, risk assessment documentation, and safety assurance processes into the same platform that manages inspections and maintenance. Hazards identified during self-inspections flow directly into SMS risk registers, creating a unified compliance and safety management system.
Does OXmaint support mobile inspections for airside teams?
Absolutely. Field inspectors use the OXmaint mobile app to complete self-inspection checklists on the ramp with GPS-tagged photos, voice notes, condition scoring, and instant corrective action submission. Data syncs to the central platform in real time, so your compliance dashboard reflects the latest inspection the moment it is completed. No more returning to the office to transcribe paper forms.
