A new project involving the use of drones by Japan Airlines (JAL) has been underway to test the potential of autonomous aircraft inspections through drone-based imagery for exterior aircraft inspections carried out at its maintenance facilities in Japan, which promises to bring about an innovation capable of cutting inspection work by 60%.
Donecle, a French manufacturer of autonomous aircraft maintenance drones, has partnered with JAL in launching the project, which involves the use of autonomous drones replacing the conventional manual visual inspections to take high-resolution aircraft photos to help mechanics to examine them, making it easier for airlines to conduct aircraft maintenance much faster while compensating for the future shortage of maintenance staff.
The move is the first of its kind in Japan since it is a practical maintenance verification project utilizing fully autonomous drones approved by aircraft manufacturer maintenance manuals to inspect the exterior of aircraft.
For travelers, the move might mean faster turnaround of aircraft and less time wasted due to maintenance delays in the future.
Why Does JAL Autonomous Drone Aircraft Inspections Matter For Travellers?
Aircraft maintenance is one of the most important parts of airline safety operations. Before aircraft return to service, maintenance teams must inspect external surfaces for possible issues such as damage, corrosion, cracks and paint deterioration.
Traditional inspections require engineers to physically examine large aircraft structures, often involving elevated platforms and scaffolding for difficult-to-reach areas.
JAL’s drone inspection project aims to make this process safer, faster and more consistent.
Key Traveller Benefits Expected From Drone-Based Aircraft Inspections
| Benefit | Impact On Travellers |
|---|---|
| Faster inspections | Could help aircraft return to service sooner |
| More consistent checks | Creates standardised inspection quality |
| Reduced maintenance workload | Helps address future technician shortages |
| Better digital records | Supports long-term aircraft condition tracking |
| Improved safety processes | Enhances maintenance monitoring |
The technology is not replacing aircraft engineers. Instead, it is designed to support mechanics by providing detailed digital information that helps them make maintenance decisions.
What Has Changed In JAL’s Aircraft Maintenance Process?
JAL and Donecle are introducing autonomous drones into the General Visual Inspection (GVI) process, a routine aircraft examination where mechanics check the outside of aircraft for visible issues.
Previously, engineers had to manually inspect the entire aircraft surface. Large aircraft require significant time because technicians must examine extensive areas, including high sections such as vertical stabilisers.
According to JAL, traditional inspections can take approximately five to 10 hours per aircraft, depending on requirements.
Traditional Inspection Compared With Drone-Based Inspection
| Category | Traditional Manual Inspection | Autonomous Drone Inspection |
|---|---|---|
| Inspection method | Engineers visually examine aircraft | Drone captures high-resolution images |
| Time required | Around 5–10 hours per aircraft | Around 2–3 hours including preparation and review |
| Working conditions | May require elevated platforms and scaffolding | Reduces need for working at height |
| Image records | Limited manual documentation | Digital image-based records |
| Inspection consistency | Depends on individual experience | Standardised flight paths and image capture |
The shift allows mechanics to focus more on analysis and maintenance decisions rather than time-consuming visual scanning.
How Does The Donecle Iris GVI Drone Work?
The drone used in the project is Donecle’s Iris GVI, a fully autonomous aircraft inspection drone developed in France.
The system uses advanced positioning and obstacle detection technology to automatically fly around aircraft following a planned inspection route.
The drone captures detailed images, which are then reviewed by mechanics through a dedicated digital application.
