Pilot Loses Control During Go-Around in Gusty Winds (N9138T)

Dry Bay, AK, US

On September 23, 1986, a Cessna 180 (registration N9138T) was involved in an aviation accident near Dry Bay, AK. Investigators recorded the probable cause as: The pilot's loss of control during a go-around due to encountering a downdraft in gusty winds with velocities varying from zero to 50 knots. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot lost control of the aircraft during a go-around maneuver due to gusty winds and a downdraft, resulting in an inverted impact with the ground.

What happened

The accident occurred at an airstrip where weather conditions were characterized by significant wind variability. At the time of the incident, the pilot reported that wind velocities fluctuated dramatically, ranging from calm conditions to gusts reaching 50 knots. The pilot elected to initiate a go-around procedure during the approach phase of flight.

During the execution of this maneuver, the aircraft encountered a downdraft. This sudden change in airflow caused the pilot to lose control of the aircraft. The plane rolled inverted and subsequently struck the ground. No specific aircraft registration or model was provided in the source text for this report.

The investigation

The available source material does not contain detailed mechanical examination results or findings from a formal investigation board. The account relies primarily on the pilot's report regarding the environmental conditions and the sequence of events leading to the loss of control.

Findings

The primary factors contributing to the accident were the gusty winds and the downdraft encountered during the go-around. The extreme variation in wind speed, from zero to 50 knots, created challenging flight conditions that exceeded the pilot's ability to maintain control of the aircraft during a critical phase of flight.

Safety message

This incident highlights the dangers of attempting go-arounds in highly variable wind conditions. Pilots must be aware that sudden downdrafts and gust shears can rapidly lead to loss of control, particularly when flying at low altitudes near airstrips without precise weather monitoring.

Probable cause

The pilot's loss of control during a go-around due to encountering a downdraft in gusty winds with velocities varying from zero to 50 knots.
