What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Aircraft departed Dallas/fort Worth international (dfw) airport enroute to charlotte, north carolina (ctl). On climb out approximately 12,000 ft. the flight attendant notified the first officer (fo) that she had found a suspicious device in seat 25D. The captain told the flight attendant to move the device to the tail compartment of the aircraft. The captain declared an emergency and returned to dfw. Upon landing approximately 3000 ft. down the runway, the tail cone departed the aircraft. Investigation revealed the flight attendant failed to disarm the tail compartment door prior to opening. Upon landing fuselage pressures reduced and allowed the tail cone to fall away from the aircraft. The aircraft rear slide did not deploy.
