Helicopter maintenance
Specialised helicopter expertise
Specialised helicopter expertise
Our dedicated helicopter maintenance division provides comprehensive support for a wide range of helicopter types. With state-of-the-art facilities and certified technicians, we ensure your helicopter fleet operates at peak performance while maintaining the highest safety standards.
Working in close coordination with our CAMO services and Quality Assurance programmes, Aviaco Technics delivers outstanding quality and technical expertise across every maintenance operation.
Maintenance on a helicopter is not optional, it is a regulatory requirement. What is optional is where each replaced part comes from. Wherever the certification path allows it, we fit repaired or recertified parts rather than new ones. For operators who choose this option, the carbon footprint of a new part is avoided and the cost of the replacement is lower.
Core services
Scheduled maintenance
Comprehensive inspection programmes and preventive maintenance schedules.

Advanced capabilities
Dynamic component repair
Our teams carry out repair and servicing of critical helicopter dynamic components, including main rotor systems, tail rotor assemblies, gearbox transmissions, and swashplate mechanisms.
Using precision tooling and advanced diagnostic equipment, we perform vibration analysis, dynamic balancing, and non-destructive testing (NDT) to ensure each component meets applicable specifications before reinstallation.
Engine services
Aviaco Technics provides engine maintenance and de-moduling services for engines commonly installed on the helicopters we service, including Safran Arriel, Arrius, and other engine types.
Our capabilities cover engine removal, module disassembly, inspection, and preparation for further specialist repair when required. We manage the full logistics and reinstallation process, ensuring complete traceability and airworthiness compliance.
For engine overhaul requirements, we coordinate with approved specialist overhaul centres to deliver a complete powerplant solution.
Tailored programmes
Preventive maintenance programmes
Customised scheduled maintenance plans aligned with manufacturer recommendations and operational requirements. We monitor component life limits, time between overhaul (TBO), and airworthiness directives (AD) compliance to avoid unplanned downtime.
Our maintenance capabilities cover the full spectrum of helicopter scheduled and unscheduled maintenance:
- • Daily and pre-flight inspections
- • 50-hour, 100-hour, 150-hour, 300-hour, and 600-hour inspections
- • Annual and calendar-based inspections
- • Phase inspections
- • 12-year major inspections
- • Airworthiness directives (AD) and service bulletin (SB) embodiment
- • Component life tracking and TBO forecasting
- • Airworthiness Review Certificate (ARC) renewal
- • Modifications and STC installations
- • Troubleshooting and defect rectification
- • Predictive maintenance recommendations
AOG & emergency support
AOG support available upon request with rapid response coordination. Our maintenance team can be mobilised to provide troubleshooting and repair solutions, helping to minimise operational disruption and return your helicopter to service as efficiently as possible.
- • AOG support coordination
- • Mobile maintenance intervention (subject to availability)
- • Priority parts sourcing
- • On-site troubleshooting and repair when required
A programme with an environmental dimension
Maintenance is mandatory on every helicopter, at every scheduled inspection set by regulation. What operators can choose is the type of parts that go back in. Wherever the certification path allows it, we use repaired or recertified parts from the Aviaco circular network, instead of new ones from the OEM. For operators who choose this option, every kilogramme of recertified part saves an average of 11.2 kgCO2e and lowers the cost of the replacement.
