1992-11-14: Glaser-dirks DG400 (N360GG) — Gary B. Gammal — Calistoga, CA

Calistoga, CA, US

On November 14, 1992, a Glaser-dirks DG400 (registration N360GG) operated by Gary B. Gammal was involved in an aviation accident near Calistoga, CA. Investigators recorded the probable cause as: THE FAILURE OF THE BRAKES DUE TO A SEPARATION OF THE BRAKE CABLE FOR UNDETERMINED REASONS. A FACTOR IN THE ACCIDENT WAS THE TAILWIND CONDITION DURING THE LANDING ROLLOUT. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

During a landing with a 15-knot tailwind, the pilot found no brake resistance. The experimental glider overran the runway and was steered into a commercial building. Investigators found a separated brake cable.

Incident Overview

A pilot landed an experimental glider with a 15-knot tailwind on the approach end of the runway, as reported by the pilot and confirmed by ground witnesses. When the pilot applied the brakes to stop the glider, no resistance was felt on the brake control handle and the glider failed to slow down. Realizing he could not stop before overrunning the end of the runway, the pilot steered the aircraft toward a wooden wall of a commercial building rather than allowing it to continue toward a chain-link fence.

Inspection Findings

An FAA airworthiness inspector examined the experimental glider and found that a 1.6mm steel cable, which runs between the cockpit brake handle and the main wheel brake actuator, had separated. The inspector reported that the reason for the cable failure could not be determined.

Aircraft and Operational Details

No additional information about the glider's type, registration, date, location, or occupants was provided in the source. The time of day, weather conditions beyond the reported tailwind, and any injuries or damage to the aircraft or building were not specified.
