The Cessna 180A pilot had been cleared to land long on the runway at Anchorage, Alaska, as requested. However, he became aware of a faster airplane that would be landing behind his plane, so he decided to land closer to the approach end so that he could exit the runway about midfield instead.
He reported that the new landing location resulted in an encounter with turbulence and a left crosswind from the lingering jet blast from a Boeing 747 that departed from an adjacent runway. The airplane veered sharply right during the wheel landing and ground-looped.
The air traffic controller had included a “caution jet blast” advisory in the pilot’s landing clearance, and FAA guidance states that pilots conducting operations under visual flight rules are expected to adjust the flightpath, as necessary, to avoid wake encounters.
The NTSB determined the probable cause as the pilot’s loss of directional control during a wheel landing.
