Safety Notice for UP Ascent 4 and Mana

On few Ascent 4 the glider went into a condition similar to deep stall after big ears maneuver was carried out (high sink rate also after releasing ears), or when brakes were pulled too far on slow speed a deep stall tendency was determined. Most of these incidents have occurred with gliders flown at low to medium take-off weights. None of these incidents have led to an accident, however, as a precaution; this safety notice must be implemented immediately.
