Event Details
The pilot reported confirming that all landing gears were down and locked before landing. After what was described as a normal touchdown, the airplane began veering to the left. Despite the pilot applying right rudder input, the airplane traveled off the runway onto grass and collided with a runway light. The nose landing gear collapsed, and the airplane came to rest upright.
Examination Findings
Following recovery, examination of the airplane revealed that the right two-piece foot was fractured at the nose landing gear actuator attach location. NTSB examination of the right foot showed evidence of fatigue, which covered a 90-degree arc and approximately 55 percent of the 0.07-inch wall thickness of the foot.
Maintenance Information
Service Bulletin (SB) 1103B, which is not mandatory for the operator of the accident aircraft and had not been complied with, calls for repetitive inspections of the engine mount for cracks in the area where the fatigue crack was located.
