According to the FAA, Air Canada A319 C-GBHR was damaged on July 7th while standing at the gate.
The blade of a concrete cutting machine came loose, stuck the wing of the A319 and ended its trajectory embedded in a luggage loader belonging to United.
Fortunately, nobody was hurt.
To be honest, I used to work for a company that did concrete cutting and I know what kind of blades they are talking about. These are giant round blades. They often aren't attached to the rest of the machine when you get there and you have to attach them yourself and tighten them. Obviously, the cutter operator didn't load the blade on right or tighten it down properly.
If it was one of those large concrete cutters such as those used on highways, the blade is about 12" and spinning at over 4000 rpm.. if one of those flew off the damage could be disasterous. This huge fast spinning blade striking a luggage cart would most like destroy the piece of luggage it hit (if there were any on it) and cause its contents to fly everywhere, most likely in a exploding fashion. Im sure if the driver of the cart heard one of these things hit his cart, I could see why it could sound like a small bomb went off

This type of work in the vicinity of parked aircraft is usually performed at night. The aircraft would have been empty, there would not have been any airline ramp workers in the vicinity, etc. The only personnel in the vicinity would usually be the contractor's personnel performing the work. We use concrete cutters nightly at IAD to perform pavement repairs or other construction work. It is never performed in the vicinity of aircraft during live flight operations. In fact, the closest they would be to a parked aircraft would normally be the vehicle service road adjacent to the gate. If the work is to be performed on the gate area, we would coordinate with the airline to have that gate empty. However, it is certainly possible that the blade traveled from an adjacent area such as a service road to strike the aircraft. As previously pointed out, you need to check your equipment and constantly think SAFETY SAFETY SAFETY. When you don't, it comes back to bite you sooner or later.
