What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
In a training flight for the commercial certificate, a Cessna 180 performed a three-point landing on runway 12 at San Carlos Airport. Rolling out after landing, the pilot and instructor encountered a crosswind gust from the right and did not provide enough aileron and rudder control input soon enough to prevent a ground loop which was confined within the runway width. Left wing, left horizontal stabilizer, and hub of left main wheel all contacted the surface. The changing wind was directly from the plane's right at 10 knots with gusts to 18 KTS.
