A private pilot landing on a 600-foot gravel airstrip encountered a sudden 45 mph wind and downdraft, causing the airplane to strike the ground and nose over, resulting in substantial damage.

Overview

A certificated private pilot was landing to the south on a 600-foot-long gravel airstrip when the aircraft was abruptly forced down by a strong downdraft and gusty wind. The airplane sustained substantial structural damage to the lower fuselage, landing gear attach points, and wing spars.

Accident Details

According to the pilot, conditions appeared calm during the approach to landing. However, just before touchdown, the wind increased to an estimated 45 miles per hour from the south-southeast. A strong downdraft then pushed the airplane toward the ground. The main landing gear struck the airstrip, causing the airplane to nose down.
