Narrative:
After mayor work and checks of the a/c the pilot took-off for a test-flight. After lift-off the left wing touched the ground and the a/c crashed. The unconscious pilot was taken to a hospital. Subconsciously he talked about the aileron. He died some days later.
It was found that the aileron-cables had been installed the wrong way around. During checks by different persons the fault was not discovered.
Cause: wrong installation of aileron-cables.
"La majorité de la commission est toutefois d'avis que le "dernier contrôle" que doit faire chaque pilote qui s'installe dans un avion ne doit pas necessairement inclure le contrôle du sens de la direction des mouvements des ailerons même si un tel contrôle aurait pu être effectueö sans grandes difficultés."
