Accidente de un SZD-8ter ZO durante la aproximación en el aeródromo de Montricher, resultando en la muerte del piloto
El 4 de agosto de 1976, un SZD-8ter ZO se estrelló durante una aproximación en el aeródromo de Montricher en Suiza. El piloto, realizando un vuelo de entrenamiento, perdió el control durante un giro base, lo que provocó que el planeador entrara en pérdida y chocara contra el suelo casi verticalmente. El piloto sufrió heridas mortales y la aeronave fue destruida. La investigación oficial identificó una velocidad y altitud insuficientes, junto con condiciones de viento racheado, como factores contribuyentes al accidente.
- Aerotow training flight: The pilot conducted a local training flight in the Jaskolka after aerotow departure from Montricher and, having found no usable lift, returned to the airfield to land.
- Low experience on type: The pilot had modest overall gliding experience and limited time on the Jaskolka type, reducing his margin for handling errors in the circuit.
- Gusty crosswind joran: A joran wind with moderate to strong gusts and associated turbulence was blowing across runway 21, increasing the risk of airspeed fluctuations during approach.
- Low, slow circuit: Witnesses observed the glider flying the landing circuit at a relatively low height and with apparently low airspeed, leaving little reserve of speed and altitude.
- Stall in base turn: While turning right onto base leg for runway 21, the glider experienced a loss of airspeed and stalled.
- Spin develops low: The stall immediately developed into a spin with about one and a half turns, with the glider descending steeply and control responses appearing sluggish or ineffective to witnesses.
- Crash - fatal: With insufficient height to recover from the spin, the glider impacted a field nearly vertically and was destroyed, fatally injuring the pilot.
