NTSB narrative
During pushback, the airplane skidded approximately 14 inches, and sustained damage to the forward pressure bulkhead, forward longerons, and nose landing gear. Both flightcrew reported that the parking brake was released prior to pushback; however, review of the cockpit voice recorder did not reveal any reference to the parking brake being released. In addition, the captain and guideperson used non-standard phraseology when discussing the pushback. A larger and more powerful tug was used for pushback, rather than the preferred tugs for regional jet aircraft. The make and model tug used for the pushback was approved, with caution, at stations where a preferred tug was not available, such as the accident station on the day of the accident.
Probable cause
The captain's failure to follow company procedures, which resulted in pushback with the parking brake set. A factor was the larger than preferred tug.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
