Collision du Ka 4 Rhönlerche II avec une balise d'aérodrome lors de l'atterrissage à Fricktal Schupfart

Le 16 août 1970, un Ka 4 Rhönlerche II a heurté une balise de piste à l'aérodrome de Fricktal Schupfart. L'incident s'est produit après qu'un élève-pilote a perdu le contrôle lors de la phase d'atterrissage suivant une approche raide. L'appareil a subi des dommages importants, mais l'élève-pilote est resté indemne. Les conditions météorologiques étaient stables sans turbulence, et aucun autre appareil ne se trouvait à proximité lors de l'incident. Le rapport souligne l'absence d'une bande d'atterrissage cible comme un facteur potentiel de l'incident.

1. Solo landing approach: During his first solo flight at Schupfart, the student flew a normal circuit and turned onto final for runway 26 after descending to about 180 m AGL.
2. Steep glissade with brakes: On final the student initiated a right sideslip (glissade) and simultaneously extended the airbrakes, producing an unusually steep approach path over the maize field.
3. Low solo experience: The student was in the early phase of solo training with limited solo time and this was his first solo landing at Schupfart.
4. No landing reference: No target landing strip or landing T was laid out on the airfield, reducing visual landing guidance for the student.
5. Loss of composure low: At about 8 m above the maize field the student, surprised by the rapid arrival in ground proximity, became disoriented and reported that he 'lost his head'.
6. Improper flare and rollout: He retracted the airbrakes and pushed the glider down slightly right-wing-low, touching down about 40 m before the runway and rolling at high speed off the landing line toward the runway edge markers without visible corrective steering.
7. Crash - no injury: The glider continued uncontrolled and collided with the concrete runway edge marker, heavily damaging the aircraft while the student remained uninjured.
