Services We Offer



Operation & Management (O&M)

We proudly support the Government of India’s "Make in India" initiative, helping build a self-reliant nation by manufacturing high-quality products locally.

Standard Operating Procedures (SOPs)

Our tailored Standard Operating Procedures (SOPs) establish a consistent and systematic approach to system operation. These procedures are designed to meet the highest safety, efficiency, and performance standards, ensuring that your systems are managed and operated with precision.

Preventive Maintenance

We offer a structured preventive maintenance program, including daily, weekly, monthly, and quarterly assessments. This proactive approach helps identify potential issues before they affect system performance, reducing downtime and enhancing the lifespan of your equipment.

Service Support Levels

Three D engineers typically provide Level 1 and Level 2 support for both OEM and third-party products. This includes routine maintenance and troubleshooting. Level 3 support is typically provided by the OEM for more complex or specialized issues, ensuring that all systems are adequately serviced at every stage.

Escalation Process

Our service structure includes a three-level escalation process, ensuring quick and effective resolution of any issues. From minor routine checks to critical interventions, our approach ensures uninterrupted operations and system reliability.

Detailed Checklists

To ensure all components are properly maintained, we use comprehensive checklists to guide each maintenance activity. This ensures that nothing is overlooked, and all critical functions are checked regularly to maintain safety and operational integrity.

At Three D, we offer comprehensive Operation & Maintenance (O&M) services designed to ensure the optimal performance, reliability, and longevity of your aviation systems. Our O&M services are fully supported by engineers trained and certified by the OEM, ensuring compliance with all tender conditions and Service Level Agreements (SLAs)

Reports & Feedback

We provide quarterly reports summarizing all maintenance activities, performance assessments, and recommendations for improvements. These reports enable informed decision-making and track the health of the systems. Additionally, customer feedback is actively sought through dedicated forms, allowing us to continuously improve our services.

Mandatory Turnaround Time (TAT)

Our strict TAT policy ensures timely response and resolution of maintenance issues, minimizing disruptions and keeping operations running smoothly.

Defect Liability Period (DLP)

During the Defect Liability Period (DLP), any necessary repairs or replacements are prioritized to meet our high standards, ensuring that all systems remain fully operational post-installation.

Breakdown Reporting & Tool Maintenance

We maintain a detailed breakdown report for each incident, tracking the issue and its resolution. In addition, a well-maintained tool kit list for engineers ensures that all the necessary tools are available and in optimal condition for effective service delivery, ensuring efficiency and preventing delays.
Three D’s O&M services provide comprehensive, effective support for your systems, ensuring high performance, reliability, and minimal downtime, while adhering to the highest industry standards.

Installation Testing and Commissioning (ITC)

Experienced Personnel of Three D are trained and certified by OEM engineers. The same trained Three D personnel act on the concept of “Train the Trainer” in the below given work matrix

Class ‘C’ (Semi skilled) Activities shall be done by local engineers of Three D.
Class ‘B’ (Skilled) Activities shall be done by OEM Trained and Certified engineers of Three D.
Class ‘A’ (Highly skilled) Power On for 1st site shall be done by OEM in presence of Three D engineers, Power On for the 2nd site shall be done by Three D in presence of OEM & Subsequent locations are fully commissioned by Three D engineers without OEM

System Integration

Our technical expertise is second to none, allowing us to fully maximise the performance of all aspects of a system installation. We follow the process stated below for SI activity.
First piece is installed by the OEM and watched over by OEM trained and certified Three D Engineers.
Second piece is installed by OEM trained and certified Three D engineers and monitored by the OEM Engineers.
All subsequent installations are handled by OEM trained and certified Three D Engineers on their own.
Once all individual units have been installed, Three D Engineers undertake any system integration activity to assemble the complete unit.
Site Acceptance Test can be either jointly handled by both the OEM and Three D Engineers or solely handled by Three D alone.

Refurbishing service/Enhancement of life

Refurbishment is an effective way to maximize the value of your initial investment while extending the service life of aviation products. Our team specializes in refurbishing, upgrading, and enhancing the lifespan of supported aviation systems such as Passenger Boarding Bridges (PBB), Baggage Handling Systems (BHS), Airfield Lighting (AFL), and more. With extensive experience in this field, Three D offers expert services across multiple brands. Our strong relationships with partners and component suppliers enable us to source replacement parts and components quickly, ensuring minimal turnaround time and maximum efficiency.

Component level Repair & Upgrades

We enter in MTOT (Maintenance Transfer of Technology) with formal authorisation from various OEMs and repair the Sub-assemblies at component level rather than sending it overseas.


Benefits:


Improved TAT
Lower cost of support
Low inventory cost

3rd party items & spares

Supply of 3rd Party Items

Three D sources third-party items like Uninterruptible Power Supply (UPS) systems, Air Conditioning units, installation materials, and consumables from local vendors at competitive prices.
This strategy helps reduce both system and long-term maintenance costs, improving our competitiveness and increasing our chances of success.

Spare and Inventory Management

Spare parts management is based on three key factors: Mean Time Between Failures (MTBF), population of units stocked, and Turnaround Time (TAT).
Our Customer Relationship Management (CRM) software tracks MTBF, installed base, TAT, and Service Level Agreements (SLAs) to ensure parts traceability.
We maintain optimal inventory levels by ordering parts before they reach the minimum stock level and generate regular Management Information System (MIS) reports to monitor part status, warranty, and obsolescence.
