He elected to immediately land the airplane in the grass safety area adjacent to the runway.

Examination of Landing Gear

The spring steel left main landing gear assembly was fractured approximately 5 inches from the fuselage attach point. An examination of the landing gear assembly was performed by the NTSB Materials Laboratory, which revealed that the gear leg fractured due to fatigue that initiated from pits on the lower surface of the leg.
