Analysis narrative
The pilot of the tailwheel-equipped airplane departing for the first time from the 750-ft-long, private grass field. During the initial climb, the right main landing gear contacted a steel fence post at the end of the runway. The airplane pitched nose down, yawed, and rolled slightly to the right. The pilot corrected with left aileron and rudder control, but the airplane cartwheeled and impacted a small shed. The airplane sustained substantial damage to both wings and the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
