An aircraft experienced a ground loop during landing at RAF Chalgrove, resulting in damage beyond repair. The pilot escaped the accident without injury.

What happened

The incident occurred during the landing phase at RAF Chalgrove. While attempting to touch down, the aircraft suffered a ground loop, causing it to leave the intended runway alignment and come to rest off-course. Following the event, the airframe was assessed and declared damaged beyond repair. The pilot remained unhurt throughout the sequence of events.

Findings

The primary mechanical issue identified was the loss of directional control during the rollout, characteristic of a ground loop. This phenomenon typically arises when aerodynamic lift is lost while the aircraft is still rolling at high speed, leading to instability in the nosewheel steering geometry. No specific contributing factors such as weather conditions or mechanical failures prior to touchdown were detailed in the available records.

Probable cause

Loss of directional control during landing resulting in a ground loop.
