Category: Accident
A Heron aircraft approached Fuenterrabia at 900m altitude, circling to reduce speed for a runway 06 approach. The aircraft overran the runway into a slough due to ineffective braking caused by a leak in the pneumatic system, originating from the landing gear selector.

The incident occurred near the Bidasoa River estuary.
Description
The Heron aircraft approached Fuenterrabia normally at an altitude of 900 m. The pilot circled the field to lose height for a runway 06 approach. Touchdown was at about 150 m past the threshold at high speed. Braking action proved ineffective and the aircraft overran the runway into a slough in the estuary of the Bidasoa River. It appeared that a leak in the pneumatic system caused the brakes to be ineffective. PROBABLE CAUSE: “The total discharge of the air system bottles, owing to the internal leak in the landing gear selector, prevented brake functioning.”
Primary Cause
Leak in the pneumatic system of the landing gear selector caused brake failure.Leak in the pneumatic system of the landing gear selector caused brake failure.Share on:
