A terminal HVAC failure during a summer peak day doesn't just make passengers uncomfortable — it triggers an airport operations alert, a potential flight delay cascade, and a regulatory notification if the environmental system supports airside operations. Runway edge light failures during low-visibility operations require a NOTAM within minutes of detection. Baggage system belt failures during peak hour can strand 4,000 bags and trigger airline penalties that dwarf the cost of the bearing that failed. OxMaint manages every airport facility asset — from terminal HVAC and jet bridges to airfield ground lighting and ILS equipment — with individual PM schedules, compliance records, and NOTAM-ready inspection logs that keep your airport operational and audit-ready.

of airfield lighting and ILS failures that cause NOTAM-driven capacity restrictions are preventable through structured lamp replacement cycles, cable insulation monitoring, and CCR constant current regulator service — all tasks that a structured CMMS PM programme catches before the NOTAM is written. OxMaint tracks every AGL circuit and ILS component with individual PM records and compliance history.
Keep your airport operational — before the NOTAM is written.

Airport Facility Failures — Where PM Returns the Most
Five failure categories account for over 89% of all airport operational disruptions caused by facility maintenance deficiencies. Baggage handling and airfield lighting together cause more than half of all NOTAM-driven capacity restrictions and airline delay penalties. OxMaint prioritises your highest-risk airport assets automatically.

Defect Priority Routing — How OxMaint Responds to Each Finding
A runway edge light outage during CAT III operations is not the same risk level as a terminal HVAC filter overdue for replacement. OxMaint routes each finding to the correct priority tier — so airside safety items are actioned within minutes while routine maintenance is scheduled for the next planned window. Book a demo to see airport facility defect routing.

Technology That Keeps Airport Infrastructure Running
Six technology integrations connect airport facility condition data to maintenance action — from AI camera systems that detect BHS belt wear without stopping the conveyor, to IoT sensors that trigger AGL circuit work orders before a lamp outage causes a NOTAM. Connect your airport infrastructure through OxMaint.
AI Predictive Analytics
5× earlier
BHS motor fault detection vs manual check
AI analyses drive motor current signatures, belt tension trends, and conveyor vibration — flagging developing faults before the belt jams and the baggage system stops.
AI Camera Vision
Real-time
BHS belt wear & runway FOD detection
Computer vision monitors BHS belt surface condition and runway pavement for FOD — flagging defects automatically without stopping operations or deploying inspection staff.
Digital Twin
3–6 mo.
Remaining life prediction for pavement & BHS
Digital twin models BHS belt fatigue and runway pavement PCN degradation — predicting replacement need months before the next inspection confirms the finding.
IoT / Online Sensors
24/7
AGL circuit, HVAC, and BMS continuous data
AGL circuit monitoring, HVAC temperature and differential pressure sensors, and BMS alarms feed OxMaint continuously — threshold breaches generate work orders before operations are affected.
SAP / ERP Integration
Pre-ordered
Lamps, belts & filters ordered before stock runs out
OxMaint PM forecasts trigger SAP purchase orders for AGL lamps, BHS belts, HVAC filters, and lubricants — stock on hand before the PM is due, not ordered reactively after failure.

Better ROI vs reactive airport facility repair
Lamp-hour counters, HVAC runtime, and BHS operational cycles all trigger PM work orders at the optimal point — not on a fixed calendar that ignores actual asset condition and usage.
Full airport facility compliance packages — under 15 minutes.
AGL inspection logs, ILS availability records, BHS service history, and PBB certifications — formatted for CAA, FAA, or airline audit from one platform.
"We had two AGL circuit failures in the same winter season — both caused CAT III NOTAMs and diverted 14 aircraft combined. When we looked at the maintenance records, the CCR on both circuits was overdue for its monthly output check. After setting up OxMaint with lamp-life tracking and CCR PM schedules, we've had zero unplanned AGL NOTAMs across 38 circuits in the two seasons since."

Frequently Asked Questions
Q1How does OxMaint track AGL lamp hours to prevent unplanned outages?▼
OxMaint stores each fixture's lamp-hour rating and operational hours from BMS or manual entry — triggering a replacement work order at 80% of rated lamp life before the lamp approaches end-of-life and risks an unplanned outage during operations.
Q2Can OxMaint generate ICAO Annex 14 compliance records for airfield inspections?▼
Yes — OxMaint produces per-circuit AGL inspection histories, CCR calibration records, and lamp replacement logs formatted for CAA and ICAO Annex 14 audit review, including NOTAM-ready defect reports when an outage is confirmed.
Q3How does OxMaint manage ILS availability records for CAT II/III compliance?▼
OxMaint logs daily ILS monitor checks, flight inspection results, and alarm histories per navaid — calculating rolling availability percentages against ICAO Annex 10 CAT III targets and flagging periods where the 99.8% threshold is at risk.
Q4How does OxMaint handle HVAC EPA 608 refrigerant compliance records?▼
Every refrigerant service event is logged in OxMaint with refrigerant type, quantity added or recovered, and the technician's EPA 608 certification reference — producing a complete compliance record for EPA inspection on demand.
Q5How quickly can an airport configure OxMaint for all eight facility maintenance domains?▼
Most airports complete all eight domains — AGL, ILS, BHS, HVAC, jet bridges, pavement, power, and security — within 21 days using OxMaint's airport asset template library, which reduces configuration time by 65% vs blank-slate CMMS setup.
