On June 12, 2003, a Boeing Stearman E75 (registration N6030V) was involved in an aviation accident near Casa Grande, AZ. Investigators recorded the probable cause as: The pilot's inadequate compensation for the wind conditions, and his failure to maintain aircraft control resulting in an inadvertent ground loop. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An airplane entered a ground loop on landing after a crosswind gust lifted the right wing, causing a veer and wingtip strike. The aircraft came to rest inverted. Weather reports indicated gusty crosswinds.
