In the Board’s words — the closest cases
- 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.
- 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.
- DCA10IA0212010-01-10 · AIRBUS INDUSTRIE A319-131 · UNITED AIR LINES INC
A mechanical failure of internal components of the right main landing gear door actuator resulting in the flight crew being unable to fully extend the right main landing gear using the normal and alternate procedures. Contributing to this incident was a circular reference in the company Flight Manual in which the Landing Gear Gravity Extension checklist referred back to the Landing Gear Unsafe Indication After Extension checklist rather than the Landing Gear - Partial Gear or Gear Up Landing checklist.
- 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.
- 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.

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).
