Incident Overview
A pilot conducting short field full stop landing practice at another airstrip later approached Stanley airport. After a low pass to assess wind conditions, the pilot chose to land with a quartering tailwind estimated at eight to ten knots.
Landing and Brake Failure
The aircraft touched down within the first one-third of the runway. Upon applying the brakes, the pilot reported no response. Approximately two-thirds of the way down the runway, the flight instructor also applied the brakes from the right seat. At some point, the parking brake was engaged as well. Despite these efforts, the aircraft continued beyond the runway end, collided with a fence, traveled down an embankment, nosed over, and came to rest inverted.
Post-Accident Inspection
After the aircraft was recovered and righted, maintenance personnel inspected the brake system. The hydraulic fluid had drained out while the aircraft was inverted. Following the addition of brake fluid, the brakes were found to be functional.
