In the Board’s words — the closest cases
  • DCA17LA1452017-06-23 · AIRBUS A321 · Delta Air Lines, Inc.
    The first officer's improper landing flare, which resulted in a hard, bounced landing, and the flight crew’s improper bounced landing recovery procedures.
  • DCA14FA0022013-10-23 · BEECH 1900C · ERA AVIATION INC
    The first officer inadvertently selecting the landing gear handle up after touchdown during the landing rollout. Contributing to the accident was the first officer's decision to reconfigure the airplane while still on the active runway.
  • 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…
  • DCA13CA0902013-05-11 · EMBRAER-EMPRESA BRASILEIRA DE ERJ 170-200 LR · SHUTTLE AMERICA CORP
    The flight attendant's decision to move two galley carts simultaneously that resulted in the second cart tipping over onto her foot.
  • DCA16CA1132016-03-05 · BOEING 767 34AF · UNITED PARCEL SERVICE CO
    the pilot flying's failure to maintain airspeed and correct pitch attitude. Contributing to the accident was the pilot's failure to maintain appropriate thrust after disconnecting the autothrottles. Also contributing was the first officer's failure to monitor the decaying airspeed and increasing pitch.

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).
