Analysis

The airplane impacted the runway while performing an S-turn maneuver while landing. The pilot reported he was following another airplane on final approach to runway 17 and had to perform S-turns to increase spacing. He noted that runway 17 was narrower than he was accustomed to, and the perceived aircraft altitude was higher than it actually was. The pilot reported there was no mechanical malfunction or failure.
