From my research I've found that (correct me if i am wrong):
Structure inspection (in B,C and D Checks) including (visual, thermography, ultrasonic inspections) looking for structure damage of different type of composit materials (like cracks, dis-bonding, delamination, water ingestion, holes, dents ... etc) in commercial airliners specially wide body aircraft takes alot of time, labor and cost.
So why isn't it done by robots which should be more time efficient, accurate and reliable? in a way that robots can do simple but mandatory inspection tasks allowing operators to focus on more skilled tasks (like engine work) reducing the overall plane down time !
Is there any robotic inspection systems exists that I didn't hear about?
How beneficial to airlines would it be to have a robotic system that would assist operators in the inspection process (in terms of time and cost) ?
