1999-08-12: Grumman American AA-5A (N9775U) — Wayton, AR

Wayton, AR, US

On August 12, 1999, a Grumman American AA-5A (registration N9775U) was involved in an aviation accident near Wayton, AR. Investigators recorded the probable cause as: The pilot's inadequate compensation for wind conditions, and his failure to maintain clearance with trees during a go-around. Factors were the gusty wind condition, and the high density altitude. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot encountered a wind gust during a go-around, causing the airplane to contact trees and terrain. The approach was turbulent, and density altitude was elevated.

Accident Overview

The accident involved an airplane that contacted trees after being hit by a strong wind gust during a go-around maneuver. The pilot reported that the approach to a 1,900-foot turf runway was very turbulent, prompting an addition of approximately 8 knots to the approach speed. During the landing flare, the airplane began to float, leading the pilot to initiate a go-around. The engine response was described as normal by the pilot.

Sequence of Events

Shortly after initiating the go-around, a strong gust of wind struck the airplane. This caused the aircraft to contact trees and subsequently the terrain. The pilot did not report any mechanical anomalies with the engine or controls prior to the wind gust.

Weather and Density Altitude

A weather observation facility located 45 nautical miles northwest of the accident site reported, seven minutes before the accident, winds from 210 degrees at 10 knots, a temperature of 102 degrees Fahrenheit, and an altimeter setting of 29.82 inches of mercury. The density altitude at the accident site was calculated to be 4,529 feet, indicating reduced aircraft performance due to high temperature and elevation.

Pilot Statement

The pilot stated that the approach was turbulent, leading to the addition of airspeed. During the flare, the airplane floated, and a go-around was initiated. The engine response was normal. The pilot did not specify any other factors or conditions contributing to the accident.

Investigation Findings

The investigation determined that the airplane contacted trees after encountering a wind gust during the go-around. No other causes or contributing factors were identified in the source material.
