From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

The flight crew conducted the post-deice checks and received clearance to taxi from air traffic ground control and was asked to pull out expeditiously onto taxiway g ahead of a B777. The flight crew began to taxi and felt the aircraft collide with something. The flight crew stopped the aircraft and contacted the deice team on the radio.
