Damage to commercial aircraft external structures ◦ Lightning ◦ Hailstorms ◦ Foreign object damage ◦ Operational damage (air bridge, supply vehicles etc)
Aircraft unavailable ½ day or longer
Requires inspection at base or remote locations ◦ Inspection involve use of gantry and staging ◦ On site engineer not always available ◦ Repair difficult away from a MRO facility

Commercial in Confidence
Detecting the ‘small’ damage ◦ Accuracy <1mm resolution (missing rivets, dents, holes) ◦ Repeatability
Doing it safely ◦ Operating close enough to the aircraft ◦ People (passenger, aircrew, ramp staff) ◦ Aircraft (movements, engines running etc) ◦ Regulation
Doing it without a significant training burden ◦ Automated Operation ◦ Reduce Close/Direct Visual Inspections
Building confidence ◦ Can sensor based data replace ‘hands on’ engineering
inspection?
