What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Per witness statements, at approximately 11:55 local time flight 3996 was being marshalled to the jetway. The left hand wing walker (employed by pinnacle airlines) did not respond quickly enough to the aircrafts left wing approaching a tug. As a result the wing struck the tug approximately three feet from the wing tip. The wing walker never motioned to the marshaller to stop the aircraft.
