As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ON 11 APRIL, 2018, AMERICAN EAGLE FLIGHT #3470 DECLARED AN EMERGENCY ON APPROACH TO O'HARE INTERNATIONAL AIRPORT, DES PLAINES, IL (KORD).

THE FLIGHT WAS FROM COLUMBUS OHIO (KCMH) TO O'HARE (KORD). THIS WAS THE INTENDED ROUTE OF THIS FLIGHT AND THERE WAS NO DIVERSION. THE AIRCRAFT WAS A BOMBARDIER CRJ-702ER, REGISTRATION N527EA.

THERE WAS A THIRD PILOT IN THE JUMP SEAT, ^PRIVACY DATA OMITTED^ WHO HAD ALREADY LEFT BEFORE INSPECTOR ^PRIVACY DATA OMITTED^ ARRIVED.

THE CREW WAS ON APPROACH TO ORD WHEN THEY SMELLED SMOKE IN THE COCKPIT. BLUISH, OILY SMOKE WAS COMING OUT OF THE CAPTAIN'S SIDE VENT. THE FLIGHT ATTENDANT ALSO SAID SHE SMELLED SMOKE IN THE CABIN. THERE WAS NO SMOKE CAUTION OR WARNING ALERT IN THE FLIGHT DECK. THE CREW DONNED THEIR OXYGEN MASKS, DECLARED AN EMERGENCY, PERFORMED THE APPROPRIATE CHECKLISTS AND CONTINUED THE APPROACH.

THE CREW SHUT DOWN THE AIRCRAFT ON TAXIWAY P3. THE PASSENGERS DISEMBARKED THE AIRCRAFT AND WERE TAKEN BY BUS TO THE TERMINAL. THERE ARE NO KNOWN INJURIES. THE AIRCRAFT WAS THEN TOWED TO G17.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft 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. For accidents, the NTSB's own investigation is the fuller record.
