NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot reported that he confirmed all landing gears were down and locked before landing. After a reported normal touchdown, the airplane started veering to the left. He applied right rudder input but 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 of the airplane following recovery revealed the right two (2) piece foot was fractured at the nose landing gear actuator attach location. NTSB examination of the right foot revealed evidence of fatigue, which covered a 90-degree arc and approximately 55 percent of the .07 inch wall thickness of the foot. 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.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The inadequate design of the engine mount by the manufacturer, resulting in collapse of the nose landing gear.
