Jantar überzieht im steilen Windensteigflug in 40-50 m AGL

Jena-Schöngleina, Germany PZL Bielsko Jantar

Bei einem Windenstart in Jena-Schöngleina wurde der Pilot eines PZL Bielsko Jantar tödlich verletzt; das Segelflugzeug wurde zerstört. Unmittelbar nach dem Abheben nahm der Jantar einen zu großen Anstellwinkel ein, den der Pilot nicht korrigierte. Die Fahrt fiel unter die Überziehgeschwindigkeit; der Jantar überzog, kippte über den linken Tragflügel ab, rotierte um beide Achsen und schlug ~100 m vom Start in leichter Rückenlage mit dem Bug voran auf. Technische Mängel wurden nicht festgestellt. Die Tauglichkeit war trotz Ausschlusskriterien in der Vorgeschichte bescheinigt worden; ob verminderte Reaktionsfähigkeit beitrug, blieb offen.

  1. Winch launch climb: During a winch launch for a planned thermalling flight, the glider climbed after liftoff from runway direction 200° at Jena-Schöngleina.
  2. Excessive pitch-up: Immediately after becoming airborne, the glider was flown into a climb with an excessively high angle of attack, resulting in an overly steep climb attitude.
  3. Low launch height: The developing abnormal attitude and speed occurred at a low winch launch height of about 40–50 m, leaving little altitude margin for recovery.
  4. No correction made: The pilot did not correct the excessive pitch and high angle of attack during the initial winch climb.
  5. Stall and wing drop: As the airspeed decreased below stall speed in the steep climb, the glider stalled and rolled off over the left wing, entering further rotation about both pitch and roll axes.
  6. Crash - fatal: From about 40-50 m height the glider struck the ground almost vertically, slightly inverted, about 100 m from the launch point; the pilot was fatally injured and the aircraft destroyed.
