An aircraft engine is not repaired. It is disassembled, inspected, measured, and rebuilt from the inside out. Every major shop visit involves removing the fan module, splitting the core, extracting the high-pressure compressor and turbine rotors, inspecting each blade with a borescope or white light scanner, measuring every disk and seal against OEM limits, and reassembling the entire module stack within tolerances measured in thousandths of an inch. The process takes weeks. It costs between $2 million and $12 million depending on the engine model and workscope. And it is the subsegment of aviation MRO where robotics adoption delivers the highest return per automated minute — because an engine on the shop floor is an engine not earning revenue, and every day saved on a shop visit is a day added to an airline's fleet utilization. The largest engine OEMs — GE Aerospace, Rolls-Royce, and Pratt & Whitney — are not experimenting with robotics in their MRO networks. They are industrializing them.

Five Engines, One Robotics Imperative: The Platform Comparison
The five most commercially significant large turbofan engines in service today each operate under different MRO economics, but the robotics technologies being deployed across their shop floors are converging on a shared set of capabilities: AI-assisted borescope inspection for hot-section blades, robotic white light scanning for disk and seal measurement, automated rotor stacking for HPC and HPT modules, and collaborative systems for receive-in-check documentation. The engines differ in architecture and workscope frequency, but the automation toolchain serving them is increasingly common.

Every Engine on the Shop Floor Is a Tracked Asset. Every Robotic Inspection System Should Be Too.
iFactory registers every borescope robot, white light scanner, HPC assembly cobot, and test cell measurement system as a managed asset with PM scheduling, calibration tracking, software version control, and inspection audit trails.
Borescope Robotics: AI-Assisted and Automated Inspection Across the Engine Core
Borescope inspection is the most frequently performed and most labor-intensive MRO task on every engine model. Each shop visit requires visual inspection of HPC rotor blades, HPT stage 1 and stage 2 blades, combustor liners, and turbine vanes — accessed through inspection ports using flexible or rigid borescope probes. The inspection generates thousands of images per engine that must be reviewed, compared against OEM limits, and documented. Three parallel technology tracks are automating this workflow across the major engine platforms.

Disassembly and Assembly Robotics: The Shop Floor Automation That Cuts Weeks from Engine Throughput
The most significant productivity gains from engine MRO robotics are not in inspection. They are in the physical disassembly and assembly of engine modules — the tasks that historically required skilled mechanics to lift, align, torque, and measure components weighing hundreds of kilograms. The deployments across Pratt & Whitney, GE Aerospace, and ST Engineering demonstrate that the highest return automation targets are the repetitive, precision-critical assembly steps that occupy the most labor hours per shop visit.
Deployment Spotlight
Pratt & Whitney Alfred Robot — HPC Rotor Assembly, Eagle Services Asia
Named Alfred by the technician who conceived it, this six-axis robot at Pratt & Whitney's Eagle Services Asia facility in Singapore assembles high-pressure compressor rotors for the PW1100G-JM GTF engine. The concept originated in 2021 from a technician's observation that the 14-hour HPC module assembly process could be automated. Design review completed in 2022, and the fully operational automated cell was running by 2023. Alfred works double shifts: prepares rotors, places them in an industrial oven for thermal expansion, cools them, and transfers them to the hydraulic stacking system. The result: assembly time cut by 50%, man-hours reduced by 87.5% from 8 hours to approximately 1 hour per rotor. Three operators were freed for higher-value tasks such as rotor balancing. Alfred is now being scaled across Pratt & Whitney's 17 active GTF MRO network sites.

Traditional borescope inspection requires a trained technician to manually guide a flexible or rigid borescope probe through each inspection port, capture images of each blade, and visually compare each image against OEM limits stored in paper or digital manuals. The technician's skill level directly determines inspection quality and consistency. For a GEnx HPC with 18 stages, the process takes approximately 3 hours per engine. AI-assisted borescope inspection, as deployed by GE Aerospace with Waygate Technologies and by Rolls-Royce with the Intelligent Borescope Method, uses three key technologies: Menu Directed Inspection with semi-transparent image overlay templates that guide the technician to capture each blade image at the correct angle and distance; AI-based Automated Defect Recognition that analyzes captured images and flags potential defects with 33.6% higher True Positive Rate than manual review; and automated 3D measurement tools that quantify defect geometry without requiring the technician to switch tools. The result is a 50% reduction in inspection time and more consistent documentation across different inspectors and facilities.

The Services Technology Acceleration Center, opened near Cincinnati, Ohio in late 2024, is GE Aerospace's dedicated facility for developing and proving MRO robotics and automation technologies before deploying them across the company's global MRO network. It is the result of a five-year joint effort between GE Aerospace Research in Niskayuna, New York and the Global Automation and Robotics Center in Bromont, Quebec. The first production technology deployed from STAC is the AI-guided white light robot inspection system, which uses two articulated industrial robots with white light optical scanners to inspect high-precision parts such as turbine disks. The second-generation system uses line-scan cameras that produce a video-like stream for real-time analysis. The system assigns numerical values to anomalies including dents, cracks, corrosion, and fretting, and creates a digital record accessible in the cloud. The goal, as stated by GE's Services Technology Leader, is to mount a part, hit go, and let the system run while the technician performs other tasks. STAC is part of GE Aerospace's $1 billion MRO investment programme announced in 2024, with $250 million allocated in the first year alone across facilities in the United States, South America, Europe, Middle East, and Asia Pacific. Book a Demo to see how iFactory manages robotic inspection assets across multi-facility MRO networks.
iFactory registers every robot, cobot, and automated inspection system in an engine MRO facility as a managed asset with a complete lifecycle record. For each system — whether it is a Pratt & Whitney Alfred HPC assembly robot, a GE Aerospace white light scanner, a Waygate Mentor Visual iQ+ borescope with AI defect recognition, or an ST Engineering automated sealant applicator — iFactory maintains the manufacturer PM schedule, calibration interval, software version history, sensor validation records, and operational uptime log. When a borescope AI model is updated, the software version is logged and the update deployment is tracked. When a white light scanner requires calibration, the PM work order is generated automatically and the calibration certificate is attached to the asset record. For MRO facilities operating under EASA Part 145, FAA, or AS9100 quality systems, iFactory provides the documented audit trail that every robotic inspection system is maintained to the same standard as the engine components it inspects.
