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
  • DCA09IA0172008-12-14 · BOMBARDIER CL-600-2B19 · AIR WISCONSIN AIRLINES CORPORATION
    the failure of the maintenance personnel to properly complete the installation, and the inspection personnel to conduct the proper functional test, of the left main landing gear uplock assembly.
  • CEN15LA1402015-02-10 · EMBRAER ERJ 190 100 IGW · US AIRWAYS INC
    An undetermined malfunction of the nosewheel steering control module, which resulted in the nose landing gear being jammed in the gear bay. Contributing to the accident was the improper rigging of the nosewheel steering feedback sensors during installation.
  • 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.
  • ENG22FA0092022-02-04 · BOEING 737-8K2 · Sun Country Airlines, Inc.
    The fatigue failure of the right main landing gear initiated by liquid metal embrittlement by cadmium at arc burn locations in the outer cylinder tooling hole area. The arc burns were likely the result of operator error during stylus cadmium plating operations during overhaul.
  • ENG08IA0252008-04-27 · BOEING MD-11 · FedEx Ecpress
    The Center Landing gear (CLG) strut failed due to intergranular (IG) cracking resulted from a contamination of the surface from the chemical used to clean that area prior to painting.

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).
