In the Board’s words — the closest cases
  • DCA17IA0202016-10-27 · BOEING 737 7L9 · Eastern Airlines Group, Inc.,
    The first officer's failure to attain the proper touchdown point and the flight crew's failure to call for a go-around, which resulted in the airplane landing more than halfway down the runway. Contributing to the incident were, the first officer's initiation of the landing flare at a relatively high altitude and his delay in reducing the throttles to idle, the captain's delay in manually deploying the speed brakes after touchdown, the captain's lack of command authority, and a lack of robust training provided by t…
  • DCA18IA0262017-11-29 · BOEING 737-932ER · Delta Air Lines
    The flight crewmembers’ failure to properly monitor the airplane’s flightpath, which caused the approach to become unstabilized and resulted in the airplane’s descent below the decision altitude while misaligned with the localizer course. Contributing to the incident were the first officer’s delay in setting go-around thrust after the captain called for the go-around and the captain’s failure to take control of the airplane after go-around thrust was not immediately set, both of which caused the airplane to come wi…
  • WPR10LA1342010-02-13 · BOEING 737-7H4 · SOUTHWEST AIRLINES CO
    The pilot’s abrupt airplane pitch change maneuver. Contributing to the accident was the flight crew’s failure to maintain the heading specified by the air traffic controller, which would have avoided the near collision course with an unidentified airplane that triggered the traffic alert and collision avoidance system resolution advisory.
  • DCA23LA1722022-12-19 · BOEING 777 · UNITED AIRLINES INC
    The flight crew’s failure to manage the airplane’s vertical flightpath, airspeed, and pitch attitude following a miscommunication about the captain’s desired flap setting during the initial climb.
  • DCA14IA0372014-01-13 · BOEING 737 7H4 · SOUTHWEST AIRLINES CO
    The Flight crew's failure to properly identify the airport and runway of intended landing. Contributing to the incident was the flight crew's failure to comply with procedures for use of navigation information and visual cues to verify the airport and runway of intended landing and the air traffic controller's issuance of erroneous airport geographic information without including the location of proximate airports.

This is the pattern in the NTSB’s own record across similar accidents — which findings it cited, what it coded, what it recommended. It is drawn from the record, not written about this case, and it never assigns blame: investigations exist to prevent the next accident (ICAO Annex 13).
