NTSB narrative
The pilot reported that, after a normal touchdown in crosswind conditions, the left main landing gear (MLG) began to shake and rattle. The shaking continued and became more severe as the airplane continued its landing roll, and the airplane subsequently began to veer to the left and exited the runway. As the airplane came to rest, the MLG spring separated from the fuselage, resulting in substantial damage to the left horizontal stabilizer and elevator.
A postaccident examination of the left MLG spring attach hardware fractured surfaces revealed that the left MLG U-bolt failed due to fatigue cracking and the MLG support bolt fractured within the shank due to shear loads.
Probable cause
The fatigue fracture failure of the left main landing gear U-bolt during landing, which resulted in the collapse and separation of the left main landing gear spring.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, cause areas. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
