| Confidence Rating: |  Accident investigation report completed and information captured |
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.
