Shortly after having landed on asphalt Runway 27, the pilot applied the brakes but, rather than providing a progressive braking action, the brakes began to “snatch” and the pilot released them. A few seconds later the right undercarriage collapsed and the pilot lost directional control. The aircraft departed the right side of the runway before coming to a stop having turned through 180°. The pilot was uninjured and vacated the aircraft unaided.
Inspection of the aircraft showed that the right drag link had failed, causing the right undercarriage to collapse and move aft into the path of the propeller. The pilot considered that the drag link had broken due to an excessive load being placed upon it when the brakes were applied.
