Commercial Aerial Application Aircraft Nosed Over After Loss of Direction Control on Sod Strip (N57706)

Altheimer, AR, US

On June 16, 1990, a Piper PA-36-400 (registration N57706) operated by AG Air Inc. was involved in an aviation accident near Altheimer, AR. Investigators recorded the probable cause as: The pilot's loss of directional control during the landing roll on a sod surface, which resulted in a ground loop and nose-over. The pilot's claim of brake failure was not substantiated by the investigation. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 3 related events involving the same aircraft type or operator are linked below.

A commercial pilot lost directional control during a downwind landing on a private sod strip, ground-looping and nosing over. Braking was attempted but deemed ineffective by the pilot.

What happened

During an aerial application operation, a commercial pilot attempted to land downwind on a private sod airstrip. As the aircraft touched down, the pilot lost directional control of the airplane. The aircraft ground-looped across the surface before veering off the runway and coming to rest in a nose-over attitude.

Following the accident, the pilot reported that he attempted to regain control of the aircraft by applying braking pressure. However, he stated that he felt as though he had no brakes available during the critical phase of the landing roll.

The investigation

NTSB investigators examined the aircraft and the circumstances surrounding the incident to determine the mechanical status of the braking system. Despite the pilot's assertion regarding brake failure, the investigation failed to reveal any evidence of a brake malfunction or mechanical defect that would have prevented effective braking.

Probable cause

The pilot's loss of directional control during the landing roll on a sod surface, which resulted in a ground loop and nose-over. The pilot's claim of brake failure was not substantiated by the investigation.
