Incident Overview
The pilot of a single-engine airplane reported an incident during taxi on a grass airstrip. After landing, while taxiing, a gust of wind from the right caused the airplane to ground loop to the left. The pilot believed the gust originated from a powerline clearing that was perpendicular to the runway.
Sequence of Events
The airplane struck a fence during the ground loop. Initially, the damage was not considered substantial. However, a later, more thorough examination of the airplane revealed that the front spar of the right wing had cracked. No systems anomalies were found with the airplane.
Examination Findings
The post-incident inspection focused on the right wing, where the front spar crack was discovered. The crack was not immediately apparent during the initial assessment. The fence strike likely imparted loads that led to the structural damage, though the exact mechanism was not specified in the source.
Wind Conditions
The pilot specifically noted the gust of wind came from the right side. The powerline clearing perpendicular to the runway was identified as a potential source of the gust, but no further meteorological details were provided.
