What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Struck by baggage tug while parked with passengers for deicing. Lights on. Windshield tug obscured by glycol spray. (.4) the airplane was standing second in line to be de-iced with position and anti-collision lights illuminated, when it was struck from behind by a baggage tug. The tug impacted the trailing edge of the left wing in the vicinity of the left wing tip. The tug driver said he completed two trips past the de-ice pad prior to the collision. Each time the tug was sprayed with de-ice solution (glycol), obscuring the windshield. When the driver attempted to clear his view with the windshield wiper after the first trip, the wiper broke off. He said, 'I couldn't see anything because of the glycol...I was on the ramp road. I couldn't see out the tug [and] never seen the aircraft. I ran into the wing.' Examination of the tug by airport police and company mechanics revealed the wiper was no longer installed. The lights and brakes were operational. According to a company training manual, 'never operate ground service equipment that is not functioning properly or in need of repair. Immediately report any vehicle in this condition to a supervisor so that corrective action can be taken.'
