2006-10-11 Accident · Delta, CO Damage: Substantial Minor injury NTSB · DEN07CA007
Reported aircraft: Huff Acro Sport I — a different aircraft that carried the N511SH registration before this airframe.
Probable cause: 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.
