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
  • DCA20LA0472019-12-23 · BOEING 737-824 · United Airlines
    Maintenance personnel’s excessive grinding of the left main landing gear’s aft trunnion pin during its initial overhaul, which caused heat damage to the base metal and led to the fatigue crack that caused the pin to fail during the accident flight. Contributing to the accident was the failure of maintenance personnel to detect the excessive grinding during the initial overhaul and the fatigue crack during the subsequent overhaul.
  • DCA23FA4172023-08-21 · BOEING 737-890 · Alaska Airlines
    Maintenance personnel’s excessive grinding of the left main landing gear’s aft trunnion pin during machining, which imparted heat damage to the base metal and led to the fatigue cracking that caused the pin to fracture during landing.
  • ENG09IA0142009-09-08 · BOEING 737 · Southwest Airlines, Co.
    The failure of the right main landing gear inboard axle due to fatigue cracking as a result of fretting damage in one of the brake mounting bolt holes.
  • DCA20LA1382020-08-19 · Boeing 767 · Federal Express
    The left main landing gear’s failure to extend due to the separation of the brake rod retaining hardware from the aft inboard wheel for reasons that could not be determined based on the available evidence.
  • 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).
