Karpf Baby Kollision mit Telefonleitung bei Außenlandung in der Nähe von Heuheim, Schweiz
Am 7. Juni 1964 ereignete sich ein Vorfall mit einem Karpf-Flugzeugbau Karpf Baby in der Nähe von Heuheim, Schweiz. Der Pilot mit begrenzter Erfahrung musste einen Landeplatz wählen, der von Hindernissen umgeben war, nachdem er an Höhe verloren hatte. Während des Landeanflugs kollidierte das Segelflugzeug mit einer Telefonleitung, was zu erheblichen Schäden am rechten Flügel und leichten Verletzungen des Piloten führte. Der Pilot erlitt eine Gehirnerschütterung und war etwa einen Monat arbeitsunfähig. Der Bericht bestätigte, dass die Kollision während eines Versuchs einer Notlandung stattfand.
- Aerotow cross-country: The pilot aerotowed from Hausen a/A and began local soaring, following other gliders southeast toward Baar.
- Unnoticed height loss: While searching for lift near Baar, the pilot failed to notice in time that he had descended into sinking air and his altitude had reduced to about 400 m above ground.
- Low experience: The pilot had limited gliding experience (about 13 hours in 78 flights), which contributed to being surprised by the rapid height loss and late decision-making.
- Limited landing options: By the time the pilot decided to land, he was low over hilly terrain where the best field was unusable due to people haymaking, leaving only a marginal field surrounded by obstacles.
- Forced landing decision: With no prospect of regaining height and unable to return to the home airfield, the pilot committed to a forced landing in a small valley field bordered by power and telephone lines and nearby houses.
- Obstacle approach: During the final approach, the pilot pulled up to clear a high-voltage line, reducing airspeed so much that the glider became almost uncontrollable as he tried to avoid nearby houses and other obstacles.
- Crash - minor injury: The glider struck a telephone line, the right wing caught on a pole and the left wingtip hit the ground, causing substantial wing damage, and the pilot, believing he was in a high-voltage line, jumped 3–4 m to the ground and sustained a concussion and shock.
