On 16 November 1959, the Antonov An-10 operating this flight crashed short of the airport runway while on final approach.

As the airliner approached Lviv, the weather was reported as temperature -1 degree C, humidity 97% with visibility at three km and the possibility of icing conditions.

Before reaching the inner marker, the aircraft descended out of the clouds and the crew switched to visual flight rules (VFR).

[1] Construction of the An-10 involved, serial number 9401402, was completed at the Voronezh aircraft factory on 5 June 1959 and it was transferred to the civil air fleet.

Testing eventually revealed that icing of the horizontal stabilizer created a supercritical angle of attack, that caused a sudden pitch down of the aircraft when the flaps are lowered to the maximum setting of 45 degrees.
