In the Board’s words — the closest cases
  • DCA19CA0792019-01-28 · Airbus A320 · Frontier Airlines
    loss of control of the tug by the driver during pushback operations as a result of the contaminated ramp, angle of the towbar, and the airplane engines being at idle thrust.
  • DEN08LA1512008-09-07 · BEECH 1900D
    The ground crew's failure to ensure airplane clearance from the building while parking the airplane. Contributing to the accident was the flight crew's unprofessional behavior and the lack of marshaling procedures for the ground crew.
  • ERA12CA0382011-10-07 · MCDONNELL DOUGLAS AIRCRAFT CO MD-88 · DELTA AIR LINES INC
    The tug driver's inadequate control of the tug while maneuvering the airplane during pushback.
  • WPR11LA3002011-05-31 · BOEING 757-222 · United Airlines
    The ground crewmembers’ failure to follow proper procedures for removing a stuck or jammed tow bar, which resulted in a ground crew injury.
  • CEN14LA4302014-08-09 · BOMBARDIER CL600 2D24 - 900 · MESA AIRLINES INC
    Failure of the tow bar shear pin, which resulted in the tug operator’s loss of control of the airplane during pushback operations. Contributing to the accident was the tug operator’s inability to communicate to the flight crew to apply the airplane’s brakes.

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).
