During a landing attempt on runway 30, the pilot lost directional control, causing the aircraft to ground loop and tip upside down. Wind conditions were measured at 200 degrees at 14 knots, resulting in a crosswind component within the manufacturer's limits.

Event Description

The pilot was attempting to land on runway 30. During the landing, directional control was lost, and the aircraft 'ground looped and tipped upside down.' No further details regarding injuries or damage were provided.

Wind Conditions

Recorded wind was 200 degrees at 14 knots. According to Aviat Aircraft, Inc., the A-1's maximum demonstrated crosswind component is 15 mph (13 knots). Consulting the Crosswind Component Chart, it was determined that the pilot was confronted with an almost direct left crosswind, specifically a 10-degree left quartering tailwind. Under these circumstances, there was a tailwind component of 2 knots and a crosswind component of 13 knots, which is less than the maximum crosswind component specified by the manufacturer.

Alternative Runway

In addition to runways 12-30, the airport has a second, longer runway: 03-21. Landing on runway 21 would have presented a 10-degree left crosswind and would have provided a 13-knot headwind component and a 2-knot crosswind component.
