1987-04-16: Boeing A75N1 (N63915) — Warren Walkinshaw — Argusville, ND

Argusville, ND, US

On April 16, 1987, a Boeing A75N1 (registration N63915) operated by Warren Walkinshaw was involved in an aviation accident near Argusville, ND. Investigators recorded the probable cause as: The pilot's failure to maintain adequate airspeed during a go-around maneuver in gusty crosswind conditions, resulting in an aerodynamic stall and subsequent collision with the ground. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot carrying fertilizer stalled the aircraft while executing a missed approach due to a missing flagger, resulting in minor injuries and ground impact.

What happened

The pilot departed with a load of 46-0-0 fertilizer intended for agricultural application. Upon arrival at the target field, the pilot determined that the ground flagger was not in position to guide the operation. Consequently, the pilot initiated a go-around maneuver.

During the turn onto the crosswind leg, which involved a 90-degree change in heading, the aircraft experienced an aerodynamic stall. The pilot attempted to recover from the stall but was unable to regain sufficient altitude or control authority before the aircraft impacted the terrain.

The investigation

Environmental conditions at the time of the incident included winds from 300 degrees at 19 knots with gusts reaching 26 knots. These wind conditions likely contributed to the difficulty in maintaining airspeed and control during the low-altitude maneuver.

Findings

The pilot sustained minor injuries in the accident. The sequence of events indicates that the stall occurred during a critical phase of flight at low altitude, leaving insufficient time for recovery.

Probable cause

The pilot's failure to maintain adequate airspeed during a go-around maneuver in gusty crosswind conditions, resulting in an aerodynamic stall and subsequent collision with the ground.
