In the Board’s words — the closest cases
  • CEN11IA3792011-06-07 · BOMBARDIER INC CL-600-2B19 · SKYWEST AIRLINES INC
    The failure of the right main landing gear (MLG) to extend normally, which resulted from the combination of a slightly worn uplock pin, the operation of the hydraulic pumps below their specified operating pressures, and contamination within the landing gear hydraulic system. Also causal to the accident was the failure of the right MLG to extend manually using the alternate gear selector handle due to the improper use of lubricant within the alternate release handle assembly, which prevented the handle from remainin…
  • DCA13FA1482013-09-01 · BEECH 1900D · GREAT LAKES AVIATION LTD
    Failure of the left main landing gear actuator internal lock to engage in the locked position for undetermined reasons.
  • 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.
  • 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.
  • ENG10IA0552010-09-28 · BOMBARDIER CL600 2B19 · SKYWEST AIRLINES, Inc.
    The failure of the left main landing gear (MLG) to extend normally and manually for reasons that could not be conclusively determined.

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).
