Probable cause
Fatigue cracking of the left main landing gear leg, which resulted in a gear collapse during landing.
NTSB analysis
The certified flight instructor stated that he and the pilot receiving instruction were practicing landings in the tailwheel-equipped airplane. He said that during a wheel landing, with the pilot receiving instruction manipulating the flight controls, the airplane's left main landing gear collapsed, and the airplane skidded to the left and contacted a taxiway sign. The instructor reported that the wind was calm at the time of the accident. Postaccident metallurgical examination revealed that the left landing gear fractured at its inboard end due to fatigue cracking and corrosion damage.
