Overview

This case study explores how AR Genie Remote Assist, an Augmented Reality (AR) platform, is transforming the landscape of remote support for maintenance, troubleshooting, and on-the-job guidance in the aviation sector. Specifically, we examine its implementation at a major Maintenance, Repair, and Overhaul (MRO) facility focused on Aircraft Engine Fan Blade repairs. The study highlights how AR-assisted remote support reduces repair time, enhances precision, and improves safety standards while minimizing costs.

Industry Challenges in Aircraft Engine Fan Blade Repairs

Engine fan blade repair in commercial aviation presents several challenges:

  • Specialized Expertise: Repairs involving composite materials and precise measurements, often require senior specialists.
  • Experts Unavailability & Delays: Limited availability of senior blade repair specialists, often located far from maintenance sites, delays critical repairs.
  • High Cost of Errors: Even minor inaccuracies during the repair process can lead to safety risks or costly rework.
  • Time-Sensitive Repairs: Incidents of Foreign Object Damage (FOD) necessitate immediate, precise intervention.


Specific Incident & Challenge

  • During a regular check of an aircraft engine, the maintenance technician found multiple damages to several fan blades caused by bird strike.

  • The damage pattern was complex, affecting both the metal (titanium) leading edge of the blades and the composite material that makes up the main body.
  • This type of damage requires specialized knowledge and skills to repair correctly. But the facility's most experienced blade repair specialist was not immediately available, working at another location 1000 miles away from the facility.


Solution: Augmented Reality Remote Assistance


In the industry where precision, accuracy, time & safety are the most crucial factors, adhering to traditional approaches, which rely on phone consultations with experts and involve flying in specialists from distant locations can lead to costly delays and potential miscommunication during critical repairs. Although traditional video calls offer some level of remote support, they fall short in providing the precise visual guidance needed for complex aerospace repair and maintenance. Augmented Reality Remote Assistance serves as the most beneficial tool to bridge the time & distance constraints by offering real-time visual assistance in challenges when specialized expertise is needed during off-hours emergencies and at remote locations.

Technicians often struggle to interpret expert instructions accurately, especially when dealing with intricate components where slight misalignments or incorrect procedures could compromise safety. With AR annotation tools, this challenge can be reduced as they overlay real-time instructions directly onto the component being worked on & also highlight the areas of errors for improved & precise troubleshooting.

These situations highlighted the urgent need for a solution that could instantly connect on-site technicians with remote experts for immediate assistance, ensuring real-time, precise guidance during complex maintenance procedures.

Why AR Genie Remote Assist?

AR Genie Remote Assist bridges the gap between on-site technicians and remote experts, providing real-time visual guidance that phone calls or traditional video conferencing cannot offer. With AR technology, technicians receive step-by-step assistance directly in their field of view, ensuring accuracy and efficiency in complex repairs.

  • Safety and Compliance: AR ensures adherence to aviation standards by guiding technicians through precise repair tolerances.

Key Features of AR Genie Remote Assist:

  • Two-Way Interaction: Two way communication allowing experts to see what technicians see and provide immediate feedback.
  • Annotation Tools: AR overlays enable precise instructions on live video feeds.
  • Scalability: The system can adapt to various maintenance tasks by integrating additional modules like 3D scanning or thermal imaging.

Implementation: AR Genie in Action

The Setup:

The MRO facility integrated AR Genie Remote Assist across its operations. The platform, accessible via web and mobile apps, connects on-site technicians with remote experts. Equipped with high-resolution cameras and AR annotation tools, technicians receive guidance directly overlaid on their AR Glasses or iPad device screens.

Execution Process:

  • Session Initialization: The technician used the AR Genie App on iPad to connect with the remote expert. He joins the remote session by entering the session code and showed the fan blade damage to the remote expert.
  • Damage Assessment: The technician streamed a live video feed of the fan blade damage, allowing the expert to assess the situation. On the live video feed, the expert uses AR tools to draw directly on the technician's screen, marking the exact boundaries of the damage.
  • Repair Phase: Using AR tools, the expert marked damaged areas, highlighted zones for blending and repair, and provided detailed instructions on composite layering and measurement points.

  • Guided Repair Execution: The expert guided the technician through grinding patterns by overlaying contour lines on the blade. During composite application, AR markers ensured proper material placement and alignment. Throughout the curing process, the expert monitored critical areas, ensuring optimal results.
  • Final Finishing: The expert guided the technician on achieving surface smoothness and completing the repair to required tolerances.

Results and Benefits

The implementation of AR Genie Remote Assist delivered transformative results:

  • Time Efficiency: Repair time was reduced by 3.5 hours, enabling quicker aircraft turnaround.
  • Improved Quality: The facility achieved a 100% first-time quality rate and zero rejections for repaired blades.
  • Cost Savings: Eliminated travel expenses and minimized delays associated with expert relocation.
  • Enhanced Collaboration: The interactive platform ensured clear communication, reducing errors caused by misinterpretation.
  • Scalable Application: The success of AR Genie Remote Assist in fan blade repair provides a model for broader applications across engine maintenance operations.

Transforming the Aviation Maintenance Landscape

Augmented Precision:

AR Genie’s ability to overlay annotations directly onto the technician’s view ensures that even the most intricate repairs are executed with precision. This capability significantly reduces the margin for error in tasks involving tight tolerances, such as repairing composite materials or inspecting solder joints.

Faster Response Times:

By connecting experts and technicians in real-time, AR Genie eliminates delays caused by travel or scheduling conflicts. This immediacy is critical in addressing incidents like bird strikes or foreign object damage, where downtime can disrupt operations.

Scalable Solutions:

AR Genie’s modular design allows facilities to expand its functionality over time. For example, adding lidar-based 3D scans or thermal imaging enhances its applicability across various maintenance scenarios.

Empowering Technicians:

AR Genie transforms how technicians approach their work. With expert guidance readily available, even less experienced personnel can perform complex repairs confidently, bridging the skills gap in the aviation industry.
