Delta, CO, USA
N511SH
Huff Acro Sport I
A crew was working on the parallel taxiway near the runway edge. The pilot taxied past the construction area and took off on runway 21. After about 30 minutes of flying, the pilot returned to the airport and made some touch-and-go landings. Another airplane entered the traffic pattern and announced he would be landing in the opposite direction on runway 03. The pilot yielded and also landed on runway 03. To avoid the construction crew, he maneuvered the airplane to the left of runway centerline. He noted that his airplane was "a short-coupled biplane," and that forward visibility in a conventional (3-point) attitude was limited. This caused him to get too close to the runway edge, and the left main landing gear went off the left side of the runway and into soft, muddy soil. The airplane swerved to the left, went through some high sage brush, struck a large rock, spun around and nosed down.
On October 11, 2006, approximately 1045 mountain daylight time, a Huff Acro Sport I, N511SH, piloted by a commercial pilot, was substantially damaged when it departed the runway and struck a large rock during landing at Blake Field (AJZ), Delta, Colorado.

The local flight originating at Delta approximately 1015. According to the pilot's accident report, a crew was working on the parallel taxiway near the runway edge. The pilot taxied past the construction area and took off on runway 21. After about 30 minutes of flying, the pilot returned to the airport and made some touch-and-go landings. Another airplane entered the traffic pattern and announced he would be landing in the opposite direction on runway 03. The pilot yielded and also landed on runway 03.

This caused him to get too close to the runway edge, and the left main landing gear went off the left side of the runway and into soft, muddy soil. The airplane swerved to the left, went through some high sage brush, struck a large rock, spun around and nosed down. The airport manager examined the airplane and reported that, in addition to the sheared landing gear, the wing spar was broken.
the pilot's failure to select a touchdown point a safe distance from the construction crew, and his failure to maintain directional control of the airplane. Contributing factors in this accident included the pilot's limited forward visibility when the airplane was in a 3-point attitude, the soft terrain, and the rock.
