MRO operations running on gut feel and lagging reports are flying blind. The gap between top-quartile and bottom-quartile performers is not talent — it is instrumentation. Organizations tracking the right 25 KPIs reduce unplanned downtime by up to 47%, cut maintenance cost per unit by 30%, and extend asset life by an average of 3.2 years. Oxmaint consolidates every metric — fleet availability, TAT performance, AOG rates, technician utilization, inventory turns — into a single real-time dashboard your ops team can act on today.

How Oxmaint Supports MRO Compliance Across Six Major Regulatory Frameworks
MRO KPI tracking is not just an operational efficiency exercise — it is a regulatory obligation across every major aviation and industrial maintenance jurisdiction. Oxmaint's documentation architecture satisfies audit requirements in all six regions below without custom configuration or compliance add-ons.
FAA Part 145 requires certified repair stations to maintain complete records of all maintenance actions, technician certifications, and quality control inspections. Oxmaint maintains timestamped work order records with technician credentials, digital sign-offs, and findings documentation. OSHA 1910 workplace safety compliance is supported through equipment inspection records and corrective action audit trails.
Transport Canada's AMO standard under CARs 573 mandates documented maintenance programs, personnel qualification records, and quality assurance procedures. Oxmaint provides AMO-compatible maintenance record structures with digital technician signatures, qualification tracking by certification type, and QA process documentation linked to each work order.
Post-Brexit, the UK Civil Aviation Authority maintains its own Part-145 equivalent framework for approved maintenance organizations. Oxmaint's record structure supports UK CAA audit requirements with complete maintenance history, component traceability, and technician qualification records structured to match the CAA Safety Regulation Group's documentation standards.
Australia's CASA Part 145 Maintenance Organization Standards impose some of the most detailed record-keeping requirements globally. With Australia's high labor costs making PM ROI especially strong, Oxmaint's planned maintenance ratio tracking directly supports both CASA compliance and cost performance simultaneously.
Germany's MRO sector operates under EASA Part-145 with additional ISO 55001 asset management standard expectations for industrial maintenance operations. Oxmaint's asset lifecycle tracking and condition scoring directly supports ISO 55001's requirement for a systematic approach to asset management decisions and CapEx forecasting.
Saudi Arabia's GACA airworthiness standards are aligned with ICAO Annex 6, with additional Smart Building and industrial maintenance expectations under Vision 2030's national transformation agenda. Oxmaint supports GACA-compliant maintenance records and provides the portfolio-level reporting infrastructure that Vision 2030 smart operations programs require.
