A teaching device, not a verdict: what the record would have looked at, next to what the Board found.

In the Board’s words — the closest cases
  • ERA09IA0562008-11-16 · DeHavilland DHC-8-311 · Piedmont Airlines
    The mechanical overload of the nosewheel steering links for undetermined reasons, which resulted in nose landing gear rotation and its subsequent wedging within the wheel well structure.
  • DCA15IA0892015-03-14 · BOMBARDIER INC CL 600 2C10 · GOJET AIRLINES LLC
    The nose landing gear’s failure to fully extend due to missing and damaged fastening hardware on the drive arm assembly.
  • DCA25LA2752025-07-26 · BOEING 737-8 · American Airlines, Inc.
    The failure of the airplane’s left main landing gear tires and wheels during the takeoff roll due to the thermal relief plugs melting and releasing tire pressure, which resulted in abnormal airplane handling characteristics and led the flight crew to reject the takeoff at high speed.
  • ENG09IA0092009-07-15 · BOEING 737-3B7 · US AIRWAYS INC
    The failure of the left hand main landing gear was caused by heat induced cracks resulting from abusive grinding/polishing of the chrome plate that was applied during the last overhaul.
  • ENG08IA0422008-10-01 · BOEING 737 · Southwest Airlines, Co.
    The right nose landing gear axle's failure from intergranular and fatigue cracking due to an earlier bearing failure.

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).
