In the Board’s words — the closest cases
  • WPR10IA1352010-02-16 · EMBRAER EMB-120ER · SKYWEST AIRLINES INC
    The flight crew’s failure to maintain clearance from the jet bridge during taxi. Contributing to the incident was the ramp marshaller's diverted attention and failure to signal the flight crew to stop at the correct position.
  • WPR09IA0332008-11-07 · BOEING 737-700 · SOUTHWEST AIRLINES CO
    The tug driver's failure to maintain situational awareness during the push back operation.
  • DFW08IA0742008-03-01 · BOEING 737-7H4 · SOUTHWEST AIRLINES CO
    The failure of the taxiing flight crew to maintain an adequate clearance from the stationary airplane.
  • DCA25LA1202025-02-02 · BOMBARDIER INC CL-600-2B19 · AIR WISCONSIN AIRLINES LLC
    The tug driver’s failure to ensure the taxiway was clear of aircraft prior to crossing, resulting in a collision with the left wing of the taxiing aircraft. Contributing to the accident was the limited visibility of the aircraft due to ambient lighting conditions and the absence of the aircraft’s nose-gear light, which reduced the tug driver’s ability to detect the aircraft’s presence in time to avoid the collision.
  • WPR09FA0682008-12-28 · BOEING 757-351 · NORTHWEST AIRLINES INC
    The failure of the tug operator and wing walker of the other airplane to maintain clearance with this aircraft during the pushback process in dark night. Also causal was the ramp controller's misinterpretation of the other airplane's gate location and her improper clearance for both airplanes to simultaneously push back from nearly opposing gates.

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).
