LN: 1125 Engines: 3x JT8D-9A 845 First flight: 06/05/1975 (22 years 10 months) Total airframe hrs: 59069 Written-off: 09/02/1998 Accident report: Status: Final Date: Monday 9 February 1998 Time: 09:54 CST Operator: American Airlines AAL Crew: Fatalities: 0 / Occupants: 6 Passengers: Fatalities: 0 / Occupants: 115 Total: Fatalities: 0 / Occupants: 121 Airplane damage: Substantial Airplane fate: Written off (damaged beyond repair) Location: Chicago-O'Hare International Airport, Illinois (ORD) USA Phase: Approach (APR) Nature: Domestic Scheduled Passenger Departure airport: Kansas City International Airport, Missouri (MCI/KMCI), USA Destination airport: Chicago O'Hare International Airport, Illinois (ORD/KORD), USA Flight number: 1340 Narrative: American Airlines AAL Flight 1340 crashed short of the runway while on a coupled instrument landing system (ILS) category II approach to runway 14R at Chicago-O?Hare. The approach was normal until the aircraft passed through 200 feet above ground level (agl), where the airplane started a pitch oscillation that grew in time. The airplane descended below the ILS glide slope, then climbed above it, and finally descended below it again, impacting the ground 300 feet short of the runway threshold. Upon impact, the airplane slid over the threshold and then off the right side of the runway, where it came to rest.. The weather at the time of the approach was ceiling overcast at 100 feet, 1/2-mile visibility in freezing fog, temperature and dew point were 28 degrees F. The runway 14R RVR was 1,400 feet variable 1800 feet. PROBABLE CAUSE: "The failure of the flight crew to maintain a proper pitch attitude for a successful landing or go-around. Contributing to the accident were the divergent pitch oscillations of the airplane, which occurred during the final approach and were the result of an improper autopilot desensitization rate." Follow-up - safety actions: NTSB issued 7 Safety Recommendations
